The bandwidth expansion of double-horn antenna with a squared probe for wireless communication applications

This article is presented the bandwidth expansion of double-horn antenna with a squared probe for wireless communication applications by using the basic structure of a monopole antenna with a double-horn waveguide to increase the gain and spread the applied frequency in the desired spectrum. The entire structure of the antenna was fabricated on a metal sheet with a thickness of t = 0.2 mm. It was designed with the CST program to improve impedance bandwidth to support wireless communication devices and WiFi system. The results of measurement found that the antenna had an impedance bandwidth of 70.99% (1.59-3.34 GHz), which conformed to support wireless communication standard.
