First of all forgive me for my mistakes, English is not my main language.
I want to design a custom pcb (i'm not an expert just a hobby), I have a working breadboard circuit of an micro controller and rf reciver and transmitter, MCU + 433mhz(rx) + 433mhz(tx) +315mhz(rx) + 315mhz (tx)
In order to receive rf remotes 433/315 codes and re-transmit them on demand.
My problem is that every module needs it's on antenna,
That means 4 DIFFERENT antennas.... (!!!!)
I do not want 4 spiral big antennas on m pcb, So i need to design a trace antenna on the pcb, Is it possible to combine all antennas together, Or i need to trace on the pcb 4 different antennas?
A. 4 trace anthennas (433rx+433tx+315rx+315tx)
B. 2 trace anthennas (433rxtx + 315rxtx)
C. 1 antenna (433+315) is it even possible?
As i said, i'm no an expert, what is the right approach to it, in order for: 1. good design+ good reception, 2. minimum space on the pcb (need to be small).
Will one of you professionals can guide me what length and size and how should the trace antenna supposed to look like.
Thanks allot!, Your help means the world to me.
The modules are : H3V4F 3V 433Mhz (433 RX) H34B 3v 433mhz (433 TX) H3V4E 3V 315Mhz (315 RX) H34A 3v 315mhz (315 TX)
