Abstract

In this paper, design of a novel broadband Canonical Tetra Sleeve Cage Antenna is presented. This antenna is designed using distributed antenna matching techniques. It has canonical shaped antenna elements and coaxial sleeves. The designed antenna operates over a wide frequency range in UHF band with omnidirectional characteristics. The proposed antenna is simulated in CST Microwave Studio, fabricated, evaluated, and the results are presented. The simulated and measurement results are in agreement. It has VSWR < 1.9:1 in frequency bands 270-330 MHz and 930-1670 MHz. The maximum value of VSWR in 250-1850 MHz is 3.3:1. The measured gain of the antenna varies from 0.6 to 5.5 dBi in the frequency range of 250 MHz to 1850 MHz. The implementation of distributed matching techniques by using canonical shaped antenna elements and tetra sleeves results in reduction of the length of the antenna by 59.86% compared to the length of a half wave dipole antenna designed at the lowest frequency. The proposed antenna finds applications in defence and wireless communication systems as a transceiver antenna.
