Experimental evaluation demonstrates wide two-dimensional beam steering in a compact leaky-wave array, indicating efficient frequency-controlled antenna tracking.
A novel method to realize 2-D frequency scanning leaky-wave antenna (LWA) array with compact architecture feature is proposed in this paper. As the operating frequency is swept, beam scanning in E-plane depends on the intrinsic phase shift along the longitudinal direction of the LWA, while the progressively manipulated phase shift of the embedded feeding network along the cross-sectional direction results in the scanning behavior in the other coupled scan dimension (H-plane). To broaden beam scanning range, maximum beam pointing at the broadside direction is designed. Based on the above method, a 2-D frequency scanning LWA array is designed, fabricated and measured, the results show that the impedance bandwidth achieves 29.9% and the maximum gain is 19dBi. Besides, the scanning beam is capable of covering an area of 60°×180° (theta×phi) by changing frequency from 14GHz to 16.8GHz.
