摘要

Based on a substrate integrated lens (SIL), a compact line source generator (LSG) for feedingcontinuous transverse stub (CTS) arrays with linear-polarized (LP) beam scanning and dualpolarized(DP) operations is presented in this paper. The SIL consists of metamaterial cellswith different sizes being arranged as concentric annulus and is printed on the center surfaceof two substrate layers. The SIL can convert the cylindrical wave generated by the feed probeof SIW-horn to the planar wave for feeding the CTS array. This rotationally symmetric SILcan be used conveniently to design LSG for feeding CTS arrays with the continuous beamscanning and DP operations, which has been verified by the fabrications and measurements.By simply rotating the SIW-horn along the edge of SIL, the 10-element LP-CTS array obtainsa measured beam scanning range of ±35° with the highest gain of 20.6 dBi. By setting twoorthogonal SIW-horns at the edge of the proposed SIL, the nine-element DP-CTS arraywith orthogonal radiation stubs is excited. The DP array obtains the gain of 20.3 dBi at thecenter frequency with the isolation of 28 dB and the cross-polarization level
