In this work, two compact quadrature phase shifters based on metamaterial transmission lines implemented by means of complementary spiral resonators (CSRs) have been designed, fabricated and measured. The structures consist on Y-junctions with output lines exhibiting 90° phase balance. The reported metamaterial-based devices present a size reduction of 64% and 77% as compared to the conventional one.
