Miniaturized Single‐Layer Quasielliptic Response HMSIW Filter With Four Transmission Poles

International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
This study presents a miniaturized filter based on half‐mode substrate‐integrated waveguide (HMSIW) resonant cavities, a bent‐line resonator, and a composite right/left‐handed (CRLH) resonator. The filter employs two HMSIW resonant cavities, which effectively reduce its size and prevent the propagation of higher‐order modes TE120 and TE220 within the ...
