Optical Control Strategies for Advanced Reconfigurable Transmitarray Antennas Operating in mmWave
Next‐generation radar and wireless communication networks increasingly rely on reconfigurable transmitarray antennas (RTAs) to achieve high‐gain beamforming via real‐time phase adjustment. While conventional RTA designs frequently integrate PIN diodes for their rapid switching capabilities and reliable isolation, the associated biasing circuitry ...

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