Re: PIFA Design
Hi, I am currently working on my bachelor proyect which consists of an antenna for a handheld device which works on the frequency ISM band of 902-928 Mhz. I've read a lot of internal antennas and I've concluded that the best antenna would be a PIFA antenna.
My problem is that, with my lack of experience, I cannot figure how would be the antenna mounted(constructed) on the PCB. For example, how does the shorting plate and the feed source connect to both the PCB and the antenna? (using SMA, coax)
Another doubt that I have is that the PCB actually consists of four layers, in which the bottom layer and one of the internal layers are both ground planes. Would the fact of having two ground planes affect the performance of the PIFA?
Thanks a lot for your help!
