New Compact and Broadband Patch Antenna Configurations for Wireless ApplicationsAbstract
We present new compact patch antenna configurations with broadband capabilities for wireless applications. Analytical, simulation, and experimental work is performed on semi-circular and quarter-circular patch antennas with a shorting pin. The resonant frequencies and radiation fields of the dominant cavity modes of the shorted patch are derived. For the shorted semi-circular patch, the broadband operation is based on the efficient excitation of two staggered modes of the patch. It is shown that a relative bandwidth of 58% is achieved with a patch area that is only 13.6% of the central wavelength squared. The shorted quarter circular patch with the same radius as the half circular one provides a relative bandwidth of about 30%.
