A Novel Design and Performance Analysis of High Gain Dual Band Dielectric Resonator Antenna Mounted with Horn

Article

Abstract

High profile rectangular dielectric resonator antennas (RDRAs) with length to height ratio of two or less are not suitable for low profile applications because of low usable bandwidth and poor gain of the RDRAs. This paper presents an improvement in the useable bandwidth and gain of the RDRAs using an horn mounted on the RDRA. The horn is fabricated with plastic sheet and painted with silver epoxy. It is observed that the RDRA mounted with horn achieves almost 100 % greater gain than that of RDRA without horn at the resonating frequencies and that too with good return loss. It is also observed that the impedance bandwidth is increased slightly. The simulation results show that the gain achieved using RDRA mounted with horn is 13.53 and 12.85 dBi while the 10 dB return impedance bandwidth is 4.4 and 5.9 % at 5.7 and 8.1 GHz respectively.
