Triple band two‐segment cylindrical dielectric resonator antenna with a novel microstrip feed for WLAN/WIMAX applications

Abstract: In this letter, a triple band two‐segment cylindrical dielectric resonator antenna with a partial ground plane is investigated. Proposed antenna is excited by a novel microstrip feed that having a microstrip line along with two ring patches. Proposed triple band antenna has been analyzed, studied, and optimized using Ansoft HFSS simulation software. Prototype of proposed structure has been fabricated and tested. Good agreement has been obtained between simulated and measured parameters. The proposed design ope… Show more

“…These radiators have a lot of advantages, such as capability to operate multiple operating bands, reducing multipath fading, and orientation insensitive. In open literature, there are three important methods available to create multiband features in dielectric resonator antenna, i.e., (i) grouping of DRA with other radiating elements, i.e., hybrid structure [3,4]; (ii) grouping of DRA with resonating element which is not directly connected to feeding structure [5]; (iii) multiple mode excitation in DRA [6,7]. Similarly, some of the research works have also been done in the area of dual-polarized/circularly polarized DRAs such as hybrid Z-shaped CDRA, aperture coupled RDRA, probefed CDRA and chamfered DRA, and rectangular DRA with square shaped slot [8][9][10][11][12].…”

“…The third technique, i.e., integrated antenna is very famous nowadays because it is a very simple method and also provides independent control over different frequency bands [10,11]. Sharma and Gangwar presented the combination of a dual-segment cylindrical DRA with annular ring shape microstrip line printed in order to obtain triple band operation [12]. Similarly, the same research group proposed a hybrid radiator, which is the grouping of annular ring metallic line and cylindrical DRA for multiband applications [13].…”

“…A triple band aperture coupled irregular pentagon shaped DRA has been proposed by Sharma and Brar but the isolation level of the given radiator is not quite high in the rejected bands (outside the operating band) . Similarly, a tri‐band dual ring shape patch fed dual segment CDRA has been proposed by Sharma and Gangwar, but the use of dual segment CDRA make the antenna more bulky . Bemani et al proposed a three segment rectangular DRA along with modified microstrip line feed with triple band characteristics.…”
