Conference PaperA High Gain Flexible Antenna for Full Duplex System at 5.8 GHz with Defected Ground StructureHossain, Abdul Rakib; Aleksandrovich Mertvyy, Aleks; Tran, Nghi; Karacolak, TutkuA novel high gain full duplex flexible antenna using PET paper and foam is presented for 5.8 GHz. Two rectangular patches are placed on top layer whereas bottom layer has defected ground structure printed on it. Patches are fed with inset line feeding. This antenna works effectively from 5.75GHz to 5.81 GHz for full duplex purpose while maintaining a radiation efficiency of 98.6% and peak gain of 8.78 dB at 5.8 GHz. This antenna is believed to be first proposed antenna which is flexible and full duplex with such high gain while working at 5.8 GHz. It also has simple structure, low cost, light weight along with good isolation and gain, which eventually makes it a good candidate for 5.8 GHz full duplex applications.2022-09-01104623062022 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (AP-S/URSI)1040 to 1041https://doi.org/10.1109/AP-S/USNC-URSI47032.2022.98862462104513National Science Foundation
