Abstract :
The design of a two-element quasi-Yagi antenna array with omnidirectional coverage is presented. The prototype array has a 50% bandwidth (|S11| les -10 dB) of 1.2-2.0 GHz. E-plane and H-plane radiation patterns of the single antenna element are shown at 1.3 and 1.7 GHz. The prototype two-element array exhibits an omnidirectional radiation pattern in the H-plane, with a maximum gain of 4.5 dBi at 1.3 GHz with ripples of less than 2.6 dB and 2.6 dBi at 1.7 GHz with ripples of less than 1.5 dB. The antenna has potential use in broadband mobile applications.
