摘要

本文介绍了用于超宽带毫米波（mmWave）工作的紧凑型多孔径耦合器，该耦合器采用人工磁导体（AMC），具有无辐射性能。椭圆形耦合孔径可在 50% 的带宽范围内实现高效运行，而固定椭圆形匹配贴片可用于任何耦合电平，以实现超过 -19 dB 的匹配电平。在 3 至 20 dB 的耦合范围内，15 dB 的指向性可实现最小的相位和振幅变化。通过对两条具有不同孔径配置的封装线路进行制造和测试，验证了其实用性和效率。

Ultra-Wideband Millimeter-Wave Tight and Loose Microstrip Aperture Couplers

Compact multiaperture couplers for ultra-wideband millimeter-wave (mmWave) operation are presented, employing an artificial magnetic conductor (AMC) for radiation-free performance. Elliptical coupling apertures are used to enable efficient operation across a 50% bandwidth, while fixed elliptical matching patches are employed for any coupling level to achieve matching levels exceeding −19 dB. Minimal phase and amplitude variation are achieved over 15 dB directivity within coupling ranges from 3 to 20 dB. Validation through fabrication and testing of two packaged lines with different aperture configurations confirms practicality and efficiency.
