Hi all,
im stimulating a 880-990MHz and 1.71 -2.17Ghz cellular PIFA pcb antenna with CST.
once done with the antenna structure, S11 and total eff. look good.
but im seeing abnormal high number(spike) at lower side for radiated efficiency. can anyone know what the root cause and how to fixed it.
thanks.
