Abstract
The proposed work depicts a compact Octuple Ridge Conical Horn (ORCH) antenna that can be utilized for Microwave Imaging (MI). The put forward ORCH is appended with a hemispherical dielectric lens to improve its gain and radiation properties. The proposed antenna achieves a bandwidth from 3 - 20 GHz with good return loss performance. The designed antenna obtains a maximum realized gain of 27.85 dBi at 20 GHz. The usage of the ORCH for MI applications is tested by checking its Specific Absorption Rate (SAR) readings in the Computer Simulation Technology (CST) simulation software. It is found that the SAR value complies with the international regulations. © 2023 IEEE.
