| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A new quarter-wavelength microstrip coupled lines coupler (MSCL) with partially narrowing the line width and slotting the other part to obtain tight coupling beyond machining limitations and high directivity simultaneously is proposed. And a new multi-element coupler using the proposed MSCL as the tightest coupling element is presented. A 10 dB multi-element coupler is designed, and excellent performances of the coupler fabricated, are shown, which are -10.3±0.9 dB coupling and greater than 20 dB isolation over 162 % of the bandwidth. It is verified that the proposed MSCL is efficient. | |
