Microstrip antenna finds a great attention for the past four decades due to their low profile, low cost and ease of fabrication. This work presents a design and analysis of pentagon shaped patch antenna operating at 5.8GHz (WLAN frequency). Substrate plays a vital role in the design antenna in terms of Miniaturization and bandwidth broadening. The comparative study is made by choosing different substrates such as FR4 and Roger in the design of proposed antenna. The effect of changing substrate material for the given antenna is observed in term of its gain, directivity, return loss, VSWR and Bandwidth. Size of the antenna is 25×25×1.6 mm3 makes it convenient for wireless communication systems. High Frequency Structure Simulator (HFSS) software is used to simulate the proposed antenna design.

Abstract


Microstrip antenna finds a great attention for the past four decades due to their low profile, low cost and ease of fabrication. This work presents a design and analysis of pentagon shaped patch antenna operating at 5.8GHz (WLAN frequency). Substrate plays a vital role in the design antenna in terms of Miniaturization and bandwidth broadening. The comparative study is made by choosing different substrates such as FR4 and Roger in the design of proposed antenna. The effect of changing substrate material for the given antenna is observed in term of its gain, directivity, return loss, VSWR and Bandwidth. Size of the antenna is 25×25×1.6 mm3 makes it convenient for wireless communication systems. High Frequency Structure Simulator (HFSS) software is used to simulate the proposed antenna design.
