Planar Reflective Phaser and Synthesis for Radio Analog Signal Processing (R-ASP)
Lianfeng Zou, Qingfeng Zhang, Christophe Caloz
A planar reflective phaser based on an open-ended edge-coupled-line structure is proposed. This phaser is the first reported phaser that combines the benefits of high resolution, i…
