摘要：
A wideband microstrip patch antenna having a hexagonal radiating patch with linear and circular polarization is proposed for multiband applications. The radiating patch is perturbed with three slits and is shorted to ground using a copper pin. The perturbation of the radiating patch with three optimum slits enhances the impedance bandwidth. Shorting of the patch to the ground plane changes a portion of the radiated frequency band from linear to circular polarization. The unique feature of the antenna is that it exhibits both linearly polarized and circularly polarized properties in a single structure. It can be used for transmission and reception of differently polarized signals simultaneously. The probe-fed antenna has an impedance bandwidth of 1.29 GHz, 42.4 percent, from 2.4 to 3.69 GHz for |S11| <= -10 dB. It has a broadside radiation pattern with a gain of 3.7 dBi at 2.5 GHz and 5.9 dBi at 3.68 GHz.
