rf - Using a 434MHz PCB Trace Antenna


Further to this question: 434MHz PCB Trace Antenna Design.


If I select a suitable 434MHz PCB antenna design and make two of them, what is the minimum extra circuitry I would require in order to de able to transmit a simple square wave from one to the other over a short distance (e.g. 30cm) ?


(10Hz Square wave) -> (Circuit A) -> (PCB Antenna 1) -> (PCB Antenna 2) -> (Circuit B) -> (10Hz Square wave out)


What could I use for circuits A and B? In this application, I would value simplicity, size and cost over reliability.


Could I literally use a crystal oscillator with enable input for A, and something like an AM radio for B?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
