Optimized Dual-Linear Polarization Frequency Scanning Microstrip Array Antenna for Cylindrical Polarimetric Phased Array Radar (CPPAR)

摘要

The design and simulation results of an optimized dual linear polarization frequency scanning microstrip antenna for CPPAR are presented. The antenna radiation pattern has been optimized to have matched horizontal and vertical polarization pointing angles at 2.8 GHz. The simulation results show that the beam pointing angle mismatch in the optimized antenna is less than 0.18° from 2.75 GHz to 2.85 GHz and is approximately 0.04° at 2.8 GHz, which are acceptable for weather measurement applications.
