Abstract
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.
