Abstract :
This paper presents the impacts of the surface waves induced by the feeding microstrip patch antenna on the performance of EBG resonator antennas. It is found that the surface waves narrow down the radiation bandwidth, widen the half radiation beamwidth in the E-plane, leading to a considerable decrease in the directivity, which should be carefully treated and abstained in the design process.
