A Novel Wideband Antenna with Added Bottom Rectangular Slabs for Gain Improvement

摘要

that makes it suitable for handheld applications. The antenna was featured with three rectangular slabs at the bottom layer in order to improve boresight gain performance over spectrum of operation. Moreover, the antenna produces semi omni directive radiation and has radiation efficiency more than 90 % over its bandwidth of operation. The antenna design along with simulation and experimental results are presented in this work.
