主　　题：Monopole antennas 

摘      要：The early detection of brain tumors presents significant challenges due to the complexity of the brain as well as the need for noninvasive diagnostic tools. This study introduces a novel antenna design optimized for noninvasive brain tumor detection. In this work, a cross slotted circular patch with a rectangular slot in the ground plane is designed in the simulator for brain tumor detection. The designed antenna operates from 1.76 GHz to 13.6 GHz with an impedance matching of greater than −10 dB. The antenna attains a peak gain of 5.8 dBi at 8 GHz. The antenna has been fabricated using the Monolithic Microwave Integrated Circuit (MMIC) technology and then tested in an anechoic chamber environment. The simulated and measured antenna performance parameters are found in agreement. The developed antenna has been used to image a target containing liquid inside a bottle covered by foam material. The liquid inside the bottle mimics the tumor material as its dielectric constant is comparable to a realistic tumor material. The target has been successfully reconstructed using the Delay and Sum (DAS) approach. © (2025), (Electromagnetics Academy). All rights reserved.
