Abstract

Purpose: The study and design of flexible patch antenna with different inset gap width fabricated on RT duriod 5880 substrate for fifth generation wireless application is presented in this article. The patch is composed of slits along the length and width separated by copper ground plane on backside and is directly fed by inset feed. The antennas resonated at multiband characteristics with better return loss (RL) suitable for fifth generation wireless and other indoor communication based applications. Radiation patters are nearly broadsided with a heart like shape for resonant band of frequency. 

Design/Methodology/Approach: The antenna is designed using a theoretical framework based on known equations as in literature. To construct and model the various antennas, the Computer Simulation Technology (CST) free student edition is employed.

Findings/Result: By the proposed simulated models, the slit based patch antenna design 1 has achieved dual band characteristics with bands namely: at fr1 = 4.5 GHz (with return loss up to -30 dB) having bandwidth 1.5% and fr2 = 10.5 GHz
(with return loss up to -26 dB) having bandwidth of 2.2%. Whereas, the design 2 has again dual resonances at lower and higher frequency bands with the reduced return loss up to -23 dB at fr1 = 4.5 GHz having bandwidth 1.5% and fr2 = 12.5 GHz with return loss up to -17 dB having bandwidth of 14%. Hence, the antenna design 2 has achieved the maximum bandwidth of 14% suitable for wireless applications, RADAR, Fixed-satellite services.

Originality/Value: The design of slits cut on patch by varying inset feed width gap on flexible substrate for 5G frequency band is investigated.
