In recent decades, demand for compact size, wideband, highly efficient antenna is increasing rapidly for wireless applications. Nowadays PIFA antennas are very useful for compact size and ease of fabrication. But PIFA antenna suffers from narrow bandwidth and low gain. So to increase bandwidth and gain of an antenna EBG structured patch antenna is very much popular nowadays.
PIFA antenna is low profile and compact size antenna and it is mostly suitable for mobile phones. PIFA uses a shorting plate to reduce the size of the antenna but it also reduces the bandwidth. Although bandwidth can be adjusted by adjusting the spacing between the shorting plate and feed point and by varying size of the shorting plate. In this thesis, a PIFA antenna is designed for GPS application and this antenna also investigated using method of moment technique, which is one of the low-frequency numerical technique. This antenna has directivity 4.717 dB and fractional bandwidth 14 % approximately.
EBG structured patch antennas are very useful for RF and microwave frequency application. EBG structure provides high gain, directivity, and wide bandwidth. These types of structures are basically used for reducing the surface wave propagation of patch antenna, which is the reason for low gain and narrow bandwidth. In this thesis, a wideband microstrip patch antenna with EBG is designed for WiMAX (3.3 GHz – 3.8 GHz) applications. This antenna is resonating at 3.5 GHz, 3.8 GHz, and 4.29 GHz with fractional bandwidth 26.3 % ranges from 3.3 GHz to 4.35 GHz
