Hi thanks for the reply, I've been simulating various antenna designs on HFSS, all on FR4 PCBs, and yes i see that the gain is limited. The bigger problem seems to be that the bandwidth is very small. I have tried the truncated corners design due to its simplicity and single feed line, but i...
I am trying to design a circularly polarized patch antenna to operate at 915MHz for an RFID reader. I intend to print the design on a PCB, as that sounds like a reasonable solution, and cheap which is a constraint. The antenna needs to be circularly polarized, and have a (max-allowed) gain of...
