Abstract

A novel dual band patch antenna in a single layer substrate is investigated. The antenna structure developed combines the advantages of the CPW (coplanar waveguide) with the advantages of the aperture-coupled microstrip antenna, and simplifies the structure of the antenna by reducing the number of metallization levels, from 3 to 2, thereby making easier the integration of the active devices. One of the most promising aspects of the new antenna consists in the capability of matching the input impedance at two frequencies with a single feed point. It is worth noting that the use of two separated frequencies allows for the relaxation of the bandwidth requirements for each frequency. Such an antenna provides dual band with the same polarizations.
