In modern days, Microstrip patch antennas become more popular because of its fascinating features such as low cost, light weight, low profile planar configuration which can be effortlessly made conformal to host surface. In order to overcome the demerits of patch antenna like low gain, low efficiency, low directivity and narrow bandwidth, it is obligatory to implement patch antennas in array configuration by creating cuts in the ground, by increasing the height of patch, rising the substrate thickness and by decreasing the permittivity of the substrate. Percentage of bandwidth of the patch antenna can also be increased by the above mentioned techniques. Circuit board FR4 (Flame Retardant 4) is used for designing this patch antenna, since it has fabulous performance during the fabrication process. In this article, design of two layered electromagnetically coupled rectangular patch antenna with microstrip-line inset-fed with minimized return loss has been proposed for the wireless devices.
