Broadband slot cut shorted sectoral microstrip antennas

摘要

Slot cut variations of shorted sectoral microstrip antennas are proposed which yields bandwidth of more than 900 MHz (>75). Formulation in resonant length at modified shorted patch modes is presented. Frequencies calculated using them show close agreement with simulated results. Using proposed formulations, procedure to design slot cut shorted sectoral antennas at different frequency is presented, which gives wideband response. Thus, proposed work gives guidelines to design shorted compact antennas at any given frequency.
