Abstract :
A patch antenna with two rectangular elements is presented. The feeding mechanism introduces a phase shift between the elements excitation, as well as between the feeding points of each element. The Return Loss versus Frequency envelope which is then formed extends greatly as each feeding point contributes to the creation of a separate resonance. In this way, wideband operation at the 2.4 GHz WiFi band is achieved. Specifically, this new configuration exhibits a bandwidth of 84.69 MHz which is a fair improvement concerning the size - bandwidth tradeoff. The results are verified in terms of Return Loss, VSWR, Input Impedance, Antenna and Radiation Efficiency, all demonstrating compensatory behaviour.
