## Abstract This paper presents two types of phase shifters using parallel coupled lines as compact and broadband couplers. Phase shifts are enabled by varying the varactor capacitances or by switching the PIN diode ON/OFF. Both have shown about 40% bandwidth within ±3.5° phase error. While an adju

## Abstract In this article, a compact tunable periodically LC loaded phase shifter using left‐handed transmission line is presented. The unique nature of left‐handed transmission line metamaterials enables reduced size, compared to conventional loaded line phase shifters realized as right‐handed t
