Base station antenna array is designed to cover frequency range from 1710 MHz to 2170 MHz. An entirely different antenna feed structure which consists of an L-plate capacitive feed, is developed and a parasitic patch is optimized to meet target design specifications. The antenna is +/-45° dual polarization with dedicated channels for each polarization. A prototype of the antenna element is built and measured to corroborate simulation results. The antenna array for BSA is designed to have an 18 dBi system gain with a VSWR less than 1.5 over the entire frequency band. © 2011 IEEE.
