Abstract

In this paper, a low-cost planar antenna array structure made of tapered dielectric image-line (DIL) radiators with a T-junction type feeding configuration is presented for Ka band frequency range. The radiation beam can be steered by changing the operation frequency. A beam deflection of 12deg in horizontal plane is achieved by 2 GHz change in the operation frequency. A 22 dB directivity is estimated for a 3-element array structure. The measurement results are presented and are compared with the simulation results.
