I am looking to study HFSS and PIFA design I would like to design a pifa with dimensions of 38mm by 20mm at a height of 7mm from the pcb that is mounted on a plastic carrier. Does anyone have any HFSS design or similair that i can study. It would be much appreciated. the frequency to be covered is 880-960 Mhz and 1710 to 1990 Mhz
you should search pifa in the search bar. some of the pifa examples are there. also, there are a couple of books by wong that you should look up. he also put out a number of papers on pifas. look for the books in the ebook section.
