摘要：
A broadband probe-fed array antenna for Ku-band applications covering 10.7-12.75 GHz, a bandwidth of 2.05 GHz, is proposed. The array antenna adopted 4x4 configuration with a parallel branch feeding network to set up required equal current magnitudes and phases. The antenna element in the array utilizes a vertical pillar to reduce the surface wave loss and increase operation bandwidth. The bandwidth of the array was about up to 30 percent (from return loss); the radiating gain of the antenna system was about 16.3 dB. The gain flatness within the bandwidth was about +/- 1.25 dB; the aperture efficiency was about 38%.
