Abstract

In this paper enhancing bandwidth and size reduction mechanism that improves the performance of a conventional microstrip patch antenna on a relatively thin substrate (about ). The design adopts contemporary techniques; L-probe feeding, inverted patch structure with air-filled dielectric, and slotted patch. The composite effect of integrating these techniques and by introducing the novel slotted patch, offer a low profile, broadband, high gain, and compact antenna element. The simulated impedance bandwidth of the proposed antenna is about 23%. The proposed patch has a compact dimension of 0.543 ×0.276 (where is the guided wavelength of the centre operating frequency. The design is suitable for array applications with respect to a given frequency of 1.839-2.293 GHz.
