TLDR
In this paper, a cylindrical dielectric resonator antenna with multiband is proposed, which gives the appreciable gain and better radiation pattern at the resonant frequencies.Abstract:
In this paper, we design a cylindrical dielectric resonator antenna with multiband. In metallic printed structure, various methods are implemented to achieve multiband in patch antennas but they are not efficient in dielectric resonators. so we are employing a new type of method called a partially ground method in cylindrical dielectric resonator antenna (CDRA) structure which gives us multiple resonance at a single antenna. This CDR antenna suitable for multiband applications. Simulation results shows that the proposed antenna achieves an impedance bandwidth from 2GHz to 6GHz covering various wireless bands like WIFI, WLAN, WIMAX, Bluetooth. The proposed antenna design gives the appreciable gain and better radiation pattern at the resonant frequencies. The result has been validated in HFSS.read more

Multi-Band Cylindrical Dielectric Resonator Antenna for Wireless Applications
TL;DR: In this paper , an improved and well-designed dielectric resonator antenna that provides multiple frequency bands for wireless/ITS applications is presented. But the proposed antenna consists of an 1×2 even power splitter with a modified slotted ground made up of a star rectangular slot with an inner slotted ring and an outer partially-slotted ring to excite a HEM mode inside the dual resonating CDRA's.
