Saya memerlukan design antenna 2.4ghz microstrip antenna bersama metamaterial

Hello, As the title says, I would like to add some sort of antenna to the HM-10 BLE 4.2 module in order to increase it's range, so the bluetooth is discoverable at bigger distances. Looking to increase the range by 5-10 meters only, nothing big. I need someone that understands antenna design and has experience improving the range of bluetooth modules. Thank you! Marius

I want a CST microwave suite expert to design an antenna. The antenna will mostly be used for microwave brain imaging. Desired antenna with increased bandwidth.

Brain phantom model is used to design antenna which is efficient compared to others. CST is used to design antenna. Better antenna is desired. Only Indians please.

You have to review our antenna and its positioning along with optimizing it for better performance.

Need a design with calculations for a tower arm on a tower for an antenna located 5 feet from the tower. The design should use galvanized square tubing with 2-inch galvanized round tubing welded on the end.  The round tubing will form a small vertical "T" to attach the vertical antenna. The project would require a simple drawing for the welder and tower climber and the basic calculations to mount a 12 lb VHF antenna.  The antenna is rated at 200 MPH.  The exposed area of the antenna is 1.3 Sq Ft. Lateral thrust is 50 lbs at 100 mph. I would like an Engineer with experience in structural support to do the design and shop drawing however this does not need to be stamped by a professional engineer. I...

I am looking to create a company logo design for my new company Jackal Entertainment. The company is in the television and film industry and so I am looking for a logo that incorporates either a TV or a film projector, that also has two humans within it (this could be two humans being the knobs on the TV and the antenna, or the two legs and the circles of the film reel inside the camera). An example of a logo I have for my music company - Music & You - may help to highlight what I mean by the inclusion of two humans in the logo. Then alongside the logo, I would like the company name Jackal Entertainment on two lines with the width of the second line matching the width of the first line.

This is a pcb modification project which was done about a year ago. A new external antenna needs to be added in this pcb , so modification requires according to the specification.

Hi, i am looking for someone who write a code between esp32- da module and RTL8201l ethernet phy and work as https client. i observed that esp32-DA pin 25 which should be EMAC_RXD0 doesn't exposed which is used for Antenna the task is map this EMAC_RXD0 to some other pin.

Thank you for your time to read in entirety & understanding. You must be very adept with embedded systems HW/FW/Antenna, UHF RFID board designing. A reasonably accurate TOF (Time of Flight) timing calculation for each RFID read/write transaction over the air is desirable. UHF range (US, Europe, AUS, Asia. US is 1st.) RAIN tags (over 100) read quickly, simultaneously over long distance (over 5 meters) via latest GEN2 protocol. Save each transaction with timestamps, RSSI value, outgoing, incoming raw, decoded messages, to a point closest to antenna and a quick retrieval of the log, realtime data etc. to host. Impact of variability of OS timings, electronic processing, latency etc. be minimized as time criticality and repeatable accuracy of responses to host is...

i want to design and develop an antenna for telemedical application. simulation using CST

Typically an antenna consists of an arrangement of metallic conductors ("elements"), electrically connected (often through a transmission line) to the receiver or transmitter. Antennas act as transformers between conducted waves and electromagnetic waves propagating freely in space.

...materials - The project will be paid in just ONE milestone at the END of successful tests - Due date for your PCB design will be 10.01.2023 - Due date for your code will be 31.01.2023 - If you fail with any of these dates, the project might be canceled from my side with no compensation. The reason for that is, that even in case you provided me with the electrical connections, this won't help me at all because I need the code to test them: the project consists of both parts together, electrical design AND code and both must mandatorily be supplied and successfully tested in order to consider the project as finished.

I have a working PCB designed in Altium. Since we will do all future work in KiCAD, this project needs to be converted to KiCAD 6.0. The PCB has a MCU that receives data from two SPI radio modules and relays the data to USB, Ethernet and Bluetooth for further processing on a PC. The PCB also has two RGB LEDs, battery management, barometer, GPS module with active antenna detection, speaker and a few other features. The attached BOM contains almost all components. The PCB size is 63x87 mm. It's a conventional four-layer PCB with two power planes. The resulting KiCAD project will have identical schematics. The CAD footprints, layout and outline will also be identical. CAD routing is not necessary to do, since any future work will require the routing to be changed anyway. The wo...

A low frequency (few kHz) switching mechanism is incorporated into the MPR. Using the switch, the reflector gain (AM Modulation) can be controlled by switching the MPR antenna elements between two states: ● The switch is OFF - When illuminated by RF power, the MPR collects the incident power and delivers it back at maximum gain. ● The switch is ON - MPR reduced reflected RF power by -3dB or more. By connecting the antenn...

We are using a Software Defined Radio (SDR) device in UHF frequency range (around 915MHz) to read the Radio Frequency (RF) messages sent and received between a RFID Reader and a Passive Gen2 RFID Tag over the air. The SDR’s antenna and the RFID Reader’s antenna are adjacent to each other. The RFID reader transmits a request message and the RFID tag responds. The RFID Reader software on a windows computer, connected to RFID Reader via ethernet or USB serial, reports both request and response correctly and are human readable. SDR Device, connected to same computer on a separate software, is also reporting the transactions with timestamp on a separate software. We see the SDR Device's messages output in our software with time stamp, but the messages are not...

Hi Bulent V., I noticed your profile and I see that you created a EV1527 based RF Receiver PCB. I am looking for a EV1527 based 433Mhz Transmitter schematic (preferably through EasyEDA) that I can use through third party websites like JLCPCB. The purpose is similar to creating a remote like the Amazon link EV1527 based RF Receiver PCB. I am looking for a EV1527 based 433Mhz Transmitter schematic (preferably through EasyEDA) that I can use through third party websites like JLCPCB. The purpose is similar to creating a remote like the Amazon link Let me know if you've a ready-to-use schematic available including the antenna positioning in the PCB. Thanks

Service of a Freelancer having CST 2022 Installed is needed.

Development of a PCB that has one ESP32 one WiFi and one Lora chip. As well as a POE Power supply and a 24V Power supply. Antenna selectable for either the Lora or the WiFi. USB Pin connecter to Programm the ESP. And Pin connector Rails to connect to the ESP Pins (Input Output) Using KiCAD for the Development would be nice but not mandatory. Creating BOM LIst of all Components and checking avalibility on the Market. I attach some samples this is about what we need but this Development does not work and it is not very good made but maybe it helps to understand what we need.

This is experimental project where we need to send Alpha numeric data to our hardware this hardware has antenna so the data from computer software goes to hardware and from there to antenna. We already have antenna designe so this hardware send alphanumeric data along with frequency to antenna.
