Abstract

This paper documents a novel design of dual-band dielectric resonator antenna exhibiting circular polarization at a high-frequency band of (7.85 GHz-7.93 GHz) in addition to linearly polarized lower frequency band of (5.12 GHz-5.49 GHz) using new materials, sapphire and TMM13i for antenna design. Sapphire and TMM13i being resistant to physical change, the novel design is suitable for weather radar application as circular polarization reduces signal attenuation in adverse climatic conditions. A four-layered structure with sapphire and TMM13i stacked alternatively with aperture coupled feed is presented. Additionally, the corners of the patch have been truncated, and a slot has been etched in order to obtain the dual-band resonance and circular polarization respectively. The design is simulated using Ansys HFSS and fabricated for measurements. The VSWR (Voltage standing wave ratio) is measured to be less than two for both the bands. The simulated and measured gains of the antenna are 5.2 dB and 4.9 dB, respectively.
