Abstract :
Traditionally, the design of 3 dB coupler on microstrip is usually accomplished by the well-known Lange coupler. This paper presents a design of a 3 dB Wiggly line coupler using micromachining technology. And a 3 dB Lange coupler using the same technology is fabricated for comparing. Compared with the Lange coupler, the Wiggly line coupler has the better directivity, larger power capacity and better gain flatness. However, the site of the Wiggly coupler is larger than that of the Lange couple, and the requirement of the technology of the Wiggly line coupler is higher than that of Lange coupler.
