Inset-fed Multiband Square Patch Antenna on Flexible substrate for Fifth-Generation Wireless Communication

Abstract

Purpose: Over a decade, the antenna has sparked considerable interest in the 5G frequency band in the wireless domain (covering industrial applications, home automation and mobile communication) because of its numerous advantages like compact, conformal to surfaces, easily integrated with the devices, etc. In general, an Antenna can be defined as a conductor which is exposed to space operable for a specific application. The purpose of the study is to design the Slotted patch antenna for 5G applications on a flexible dielectric substrate material which makes the antenna compact in its design aspect.

Design/Methodology/Approach: Initially, the antenna design is carried out using the theoretical framework based on the available equations. The microwave studio software - Computer Simulation Technology (CST) is used to create and model the different antennas. 

Findings/Result: Based on the simulated models, the slotted patch antenna design 5 has 2 bands namely: 3.25 GHz, the return loss is -17.47 dB, and 5.89GHz, the return loss is -21.37dB. Whereas design 6 has 4 resonant bands measured at 2.04 GHz, the return loss (RL) is -11.68 dB, at 5.80GHz, the RL is -22.36 dB, at 7.14 GHz, the RL is -28.71 dB and at 8.83 GHz, the RL is -13.36 dB. The maximum bandwidth achieved for slotted patch antenna design 5 is 5% and the maximum bandwidth achieved for slotted patch antenna design 6 is 8%. Whereas the design of Multi slotted patch antenna flexible substrate design 7 and design 8 has the maximum achieved bandwidth of 10 %.

Originality/Value: The design of slotted patch and multi slotted patch antenna using inset feed method on a flexible substrate for 5G frequency band.
