A theoretical study on ‘Planar Inverted F Antenna Technology’ is performed. Several research works done on PIFA are categorized and discussed. All the available theoretical, experimental and numerical method based analysis techniques are reviewed. Presence of PIFA in the category of low profile antenna in various application areas is reported. Effect of finite ground plane in wireless antenna applications...
A compact circularly polarized (CP) vertical patch antenna is presented that employs a microstrip to slot-line transition for a wideband operation. The antenna is composed of two vertical patches, which are shaped as helix to obtain a broadband CP performance. The loop structure and the vertical overlap configuration lead to significant size reduction as much as 48% when compared to that of the printed...
