This letter presents a highly integrated power amplifier (PA) antenna with the capability of frequency tuning. A planar inverted-F (PIFA) is used to directly match PA transistor. mitigates lossy output matching network in PA-integrated (PAIA). In order achieve wide tuning range, combination capacitors loaded at PIFA control input impedances so that can be maintained The analysis and design proc...
