Abstract

In this letter, novel designs of a triple-band linearly polarized patch antenna as well as a dual-band dually polarized patch antenna are proposed. A square slot is etched out along the diagonal of a conventional patch antenna, which is further loaded with a modified mushroom unit cell to achieve a triple-band operation. The lower-order modes are combined to achieve a circularly polarized mode, thus leading to the design of a dual-band dually polarized patch antenna. Both the triple- and dual-band prototypes of a modified mushroom loaded patch are fabricated to validate the results obtained in simulation. The results obtained in both the electromagnetic (EM) simulations and measurements are in good agreement.
