Description
Summary:A dielectric loaded antenna is proposed in this paper for wireless communication applications. The proposed antenna has been optimized by using the covariance matrix adaptation evolutionary strategy (CMA-ES) optimization method to achieve the impedance bandwidth requirement of the upper band of wireless local area network (WLAN) band systems, and to introduce nulls in the radiation pattern at the undesired directions for interference cancellation purposes. The antenna has a compact size of 40 × 40 mm2. 3D electromagnetic simulation software, CST STUDIO SUITE is used to simulate the proposed antenna. To validate the performance of the proposed antenna, the antenna is fabricated and tested. A good agreement between simulation and measurement is obtained.
