Abstract

This article presents the design of a compact dual wide-band microstrip antenna. It also describes the simulation of its operation and provides the results of electrical parameter and radiation characteristics measurements. The designed antenna is intended to operate in two ranges. The first covers frequencies from 3.8 to 8 GHz and all the U-NII antenna ranges (U-NII-1, U-NI-2A, U-NII-2B, U-NII-2C, U-NII-3, U-NII-4, U-NII-5, U-NII-6, U-NII-7, U-NII-8) defined in the IEEE-802.11a standard (5.150 to 7.125 GHz). The other covers frequencies from 11.34 to 20.64 GHz and the Ku band (from 11.7 to 12.7 GHz). The performance of the antenna, developed using CST Microwave Studio and Matlab software, was verified through simulation. Then, a prototype was manufactured and was subjected to measurements in an anechoic chamber. Results of the simulation and the measurement campaign were compared against six other dual-band antenna designs available in the literature. Comparison of the parameters of the proposed design and characteristics of other antennas with a similar profile, selected from the literature, shows that the operating bandwidth of the proposed solution with respect to the S\textsubscript{11} parameter is the largest, reaching 88.13% for the lower operating band and 59.93% for the upper operating band.
