U-Slot Microstrip Patch Antenna for Wireless Application
In this paper, the authors simulate and design a single u-shaped microstrip patch antenna with operating frequency of 5.5GHz. This type of antenna has to be designed using a substrate having a low dielectric constant in order to achieve low return loss. The microstrip antenna consists of the rectangular patch on the top of the dielectric substrate and over which a u-shaped slot has been made to reduce the size of the antenna. The reduction in the size of the antenna results in improved gain and the return loss of the antenna.
