Bandwidth Enhancement of Microstrip Array in Wireless Communication with Optimized Geometry

With improved technology for communication, antenna is an essential component. A single element antenna cannot satisfy the desire of the user. The antenna array is an alternative to this solution. In this paper, an antenna array has been designed for application in wireless communication. A triangular patch element is considered for 3 × 3 array antenna. These elements are placed around the central patch that is of rectangular and received the feeding. The work is emphasized on location geometry of the patches. The geometry of the patch is optimized using Genetic Algorithm techniques. It is found that the optimized antenna provides better result as compared to Unoptimized one in terms of bandwidth and return loss. Also, the radiation pattern is clearly observable. The bandwidth resulted as 2.5 GHz at the 15.5 GHz frequency with a return loss of 26.5 dB.
