Improving the Performance Parameters of Microstrip Patch Antenna by using HFSS
Journal Title: INTERNATIONAL JOURNAL OF COMPUTERS & TECHNOLOGY - Year 2014, Vol 13, Issue 11
Abstract
A high-directivity patch antenna with broadside directivity is appealing, since a constrict beam can be obtained without the need of using an array of antennas. Hence, the solution becomes barer as there is no need for a complicated feeding network. In this senate, this paper presents a novel patch antenna design with high directivity in the broadside direction by using HFSS. The proposed finite element method is employed to design the rectangular microstrip patch antenna. The patch is divided into symmetrical rectangular pieces and has a small overlap area among them. This averts optimized geometries where rectangular pieces have only an infinitesimal connection. Hence, the proposed method is robust for manufacturing. The antenna functions in a higher order mode at 8.40 GHz, 16.5 GHz and the geometry fits inside a patch of 41mm £ 26mm on a substrate with a relative permittivity of 2.1 and a thickness of 1.75mm resulting in a gain of 9.94 dBi. The strength of this design is the use of FEM to select the optimized shape and the feeding place instead of a known shape and a fixed feeding place. The antenna has been fabricated and the simulation results are in good agreement with the measurements. These results in a less complicated design of a single high-directivity patch and enhance the gain and improve bandwidth.
