摘要
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 x 14.9 mm(2), while a conventional coupler is 32.6 x 27.8 mm(2). Thus, the proposed coupler is considerably smaller than the conventional coupler.
