摘要：
A two-element array antenna using rectangle patch elements for UWB application is proposed. A novel Marchand balun is chosen as the feeding structure. This balun excites signals of Equi-amplitude and 180 degree phase difference. The radiation pattern of the antenna is omnidirectional at H-plane and bidirectional at E-plane. The measured VSWR is less than 2 over the frequency bandwidth (3-11 GHz). The simulated gain is 2.8-8.49 dB, especially increased at higher frequencies because of the array factor effect. The measured results are in good agreement with the simulated results.
