Title: Wideband dual-linear polarized microstrip patch antenna
Author: Smith, Christopher Brian
Abstract: Due to the recent interest in broadband antennas a microstrip patch antenna was developed to meet the need for a cheap , low profile , broadband antenna . This antenna could be used in a wide range of applications such as in the communications industry for cell phones or satellite communication . Particle Swarm Optimization was used to design the dual -linear polarization broadband microstrip antenna and impedance matching network . This optimization method greatly reduced the time needed to find viable antenna parameters . A dual input patch antenna with over 30 % bandwidth in the X -band was simulated using Ansoft's High Frequency Structural Simulator (HFSS ) in conjunction with Particle Swarm Optimization . A single input and a dual input antenna was then fabricated . The fabricated antennas were composed of stacked microstrip patches over a set of bowtie apertures in the ground plane that were perpendicular to one another . A dual offset microstrip feedline was used to feed the aperture . Two different layers were used for the microstrip feedline of each polarization . The resulting measured impedance bandwidth was even wider than predicted . The antenna pattern was measured at several frequencies over the antenna bandwidth and was found to have good gain , consistent antenna patterns and low cross polarization .
