Abstract

An alternative radiation stabilization method has been presented for patch antenna. With this method, side radiation could be suppressed when a conductor ring and a circular slot both with the width of a quarter wavelength are placed on the same layer and around patch antenna. An experimental structure has been simulated and the distance l from antenna part to conductor ring is optimized using parametric function of HFSS software. Measured results given in this letter obviously indicate that not only the side radiation from the boundary of substrate could be suppressed effectively, but also the antenna directivity could be adjusted and enhanced after this method has been carried out. Both simulation and measurement indicate that when the distance l is set to one guided wavelength(λg), side radiation could be suppressed the most effectively and the return loss of patch antenna is only slightly affected.
