A 2-Pin Loaded Patch as a Multiband Antenna for Wireless Communication
Abstract
A new microstrip patch antenna capable of dual or triple band operation is proposed. The patch is circular in shape and is loaded by two shorting pins having a certain angular separation of 2 alpha. The dominant cavity modes of the patch antenna are studied using a developed rigorous theory. It is found that the first three dominant modes of the loaded patch can act as good radiators with distinct resonant frequencies hence providing dual or triple-band operation. Salient mode characteristics such as the resonant frequency, radiation power, and the radiation quality factors are derived. Numerical results showing the dependence of these parameters on the angular separation angle 2 alpha and the patch geometry are presented and compared with several simulations obtained by Zealand IE3D software.
