Inset fed horizontal wide u-shaped slotted microstrip antenna for multi-band operation

Abstract

A multi-band horizontal wide U-slotted patch antenna is proposed for wireless communication. Along with the horizontal wide U-slot, the proposed antenna also consists of four truncated corners along with inset feeding for proper antenna matching. The proposed antenna design has three distinct simulated resonating frequencies i.e., 4.7 GHz, 6.8 GHz and 9.8 GHz having-10 dB return loss band width as 111.1 MHz, 245.1 MHz, 998.6 MHz respectively while measured resonating frequencies are observed as 4.75 GHz, 7.1 GHz and 10.2 GHz having-10 dB return loss band width as 539.1 MHz, 410.6 MHz, 2.0834 GHz respectively. The proposed antenna results are examined using High frequency structure simulator tool and then verified through measured results . Thus, the proposed antenna is applicable for frequency bands like S band, C band and X band.
