A dual-polarized L-probe fed patch antenna with various ground plane dimensions and shapes were simulated. By putting the two flanges of the U-shaped ground plane in parallel to the E-plane (φ - 90°) and with suitable distance (0.21λ) to the probe, good isolation can be obtained. Reducing the width of the ground plane to maintain the isolation bandwidth and increase the horizontal beamwidth to 75° is also investigated.
