| Popis: | In this article, a new compact branch-line coupler with third harmonics suppression using the meander T-shaped line is suggested. The meander T-shaped line works similar to a bandstop filter at the second and third harmonics frequencies. The size of the proposed coupler is 22.2 × 14.9 mm2, while a conventional coupler is 32.6 × 27.8 mm2. Thus, the proposed coupler is considerably smaller than the conventional coupler. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1382–1384, 2014 |
