Abstract :
This paper presents a parallel stubs structure with simple matching network which can provide a constant differential phase shift using uniform transmission lines that can realise a wide bandwidth of more than 120%. For demonstration purposes, two broadband phase shifters are designed, fabricated, and measured to give excellent performance for wireless local area network and ultra wide band applications respectively.
