Abstract
This paper demonstrates a completely new technique to obtain high-selective filtering response of a rectangular dielectric resonator antenna (DRA). The proposed filtering antenna mainly composed of a rectangular DRA driven by a stair shaped slot on the ground plane and a feed line with multiple bandstop characteristics. Two pairs of band-rejection resonators with dissimilar resonant frequencies is integrated in the 50 Ohm microstrip line to generate four transmission zeros on either side of passband which offers the filtering response for the rectangular DRA. Just by inserting two identical pair of band-rejection resonators in feed below the ground plane, the proposed DRA exhibits a consistent broadside gain response in passband with skirt selectivity at both upper and lower band-edge with four radiation nulls. Three distinct resonance frequencies of TE111 mode are excited in close proximity within the DRA due to the different loading effect of band-rejection resonators in the feed, enhancing the operating bandwidth of antenna to 11.8%.
