Hello, this is an HFSS simulation of IEEE paper 'Circularly Polarized Square Patch Antenna with Square Slots for RFID
Reader Applications' written by 'N. Gautam* (1), P. Deo (2), A. Mehta(1), D. Mirshekar-Syahkal(2), P.J. Massey and H.
Nakano(3)'.
This paper discussed the development of a circularly polarized RFID Patch antenna at 880Mhz. For some reason, I cannot attain the dip at the accurate frequency. Can some one please look into this?
I can post the paper here too if its not against the rules.
