The small bandwidth of microstrip antennas still remains their major drawback and continues to be a major concern. One method used to improve the bandwidth is to make the patch on a wedgeshaped substrate. Only experimental observation on this has been reported. The present work is on a rectangular antenna, whose nonradiating edge is on a plane that intersects the ground plane with an angle, θ. An expression has been derived for the resonant frequency in the dominant mode. The theoretical findings are supported by experimental observation.
Mishra et al. (1990) studied this question.
