Enhanced Bandwidth And Radiation Specifications Of U-Shape Multislot Antenna For Wimax Application

Abstract: Despite the many recompense of slot antenna, they do have some extensive drawbacks. One of the main limits with slot antennas is their essentially narrowband performance due to its resonant nature. With bandwidth as low as a the minority present; broadband applications using conventional patch designs are limited. So for the antenna size is reduced and bandwidth improvement U-shaped multislot antenna used. We are proposing a U-Shape multislot antenna to achieve the 2-3GHz frequency range.The simulation process has been done by using high frequency structure simulator (HFSS). The main properties of antenna such as bandwidth, return loss, VSWR , gain, radiation pattern has been analyzed.
