Abstract :
The radiation pattern of aperture stacked patch (ASP) antennas is improved. In the proposed geometry, the patch shape is designed such that the effective propagation constant of the antenna is decreased and therefore pattern degradation due to higher order modes is eliminated. The results show that the operational bandwidth of the proposed structure is increased from 68% to 76% compared to the traditional ASP.
