The accomplished DGS is included as a part of a whole in the ground plane under the patch antenna to improve its performances. An archetype of the antenna was simulated with the RT Duriod-5880 substrate and verified. A FEM based electromagnetic solver, Ansoft HFSS is used for analysis of the result. The proposed antenna is outlined to operate over frequency range from 10.75 GHz to 17.3 GHz. Various measurable factors are acquired which

Having advantages like low-profile, low weight, high efficiency, conformable to planar and nonplanar surfaces, simple and inexpensive to forge using modern printed-circuit technology, when mounted on rigid surface it is mechanically robust, consistent with MMIC designs in terms of resonant frequency, polarization, pattern and impedance is very versatile [2]. Accordingly microstrip antennas are a class of miniaturized antennas. Microstrip antennas are planar resonant caries. They leak from their edges and emit rays. Microstrip antenna in its simplest pattern is as shown in Figure 1. They are comprised of a metallic patch on a grounded substrate. One side of it composed of a dielectric substrate of radiating patch with a ground plane on the other
