在这封信中，提出了一种磁电（ME）偶极子天线，具有薄型、易于集成、宽带和高增益的特点。 ME偶极子由矩形贴片和金属通孔组成，嵌入在基板集成间隙波导（SIGW）上蚀刻的方形孔径中。特别是，ME偶极子由共面带状线馈电，该共面带状线在SIGW中设计，以实现0.19λg的低剖面（λg是中心频率处的波导波长）。测量结果表明，天线的10 dB阻抗带宽为29%，范围为22.4至30 GHz，平均增益为8.04 dBi。此外，天线发射稳定的辐射方向图，并通过远场测量进行验证。
In this letter, a magnetoelectric (ME) dipole antenna with characteristics of low profile, easy integration, wide band, and high gain is proposed. The ME dipole is composed of rectangular patches and metallic via holes, and is embedded in a square aperture etched on substrate-integrated gap waveguide (SIGW). In particular, the ME dipole is fed by a coplanar strip line, which is designed in SIGW to realize a low profile of 0.19λg (λg is the guide wavelength at center frequency). The measurements show that the 10 dB impedance bandwidth of the antenna is 29%, ranging from 22.4 to 30 GHz, with a mean gain of 8.04 dBi. Furthermore, the antenna emits a stable radiation pattern, validated by the far-field measurements.
