Abstract

The array covers the L-band and S-band range frequencies used for multifunctional applications and operate between 1.61 GHz and 2.492 GHz. The quad frequency antenna resonates at four frequencies 1.176 GHz, 1.575 GHz, 1.6 GHz, and 2.492 GHz, which cover the L-band and S-band frequencies. The configurations of both antennas are layered patches. Performance measurements of the two antenna arrays have been compared, including side lobe level, return loss, and gain. Both the antennas are fabricated using affordable, easily accessible FR4 Epoxy. By implementing thinning for both array antennas, gain values are observed, and good performances are obtained.
