Gain enhancement in a novel square microstrip patch antenna using hybrid substrates

This paper presents a novel square microstrip patch on the hybrid substrate that includes a square an unbiased ferrite ring in the Rogers TMM4 substrate, initially at a distance of the one-quarter of the free space wavelength from the edges of patch. Using CST Microwave studio, the results of the patch antenna above a conventional substrate (i.e., Rogers TMM4 substrate without any ferrite ring) and above the hybrid substrate (Rogers TMM4 substrate with ferrite ring) are simulated and compared. The proposed microstrip path antenna resonates at the 5.8 GHz suitable for wireless local area network applications. By this substrates design there is enhancement in gain as well as bandwidth of microstrip patch antenna.
