摘要

提出了一种宽带共面波导馈电锥形缝隙天线。采用微带-线-槽过渡结构激励槽辐射器。宽带性能是通过非周期连续缩放结构实现的。制作的天线原型具有61 × 25 × 0.16 mm3的紧凑尺寸。测量结果表明,该天线在超宽带(10 - 40 GHz)范围内的回波损耗优于10 dB。在该波段测量的峰值增益范围为6 ~ 12.5 dBi。宽带特性使该天线在5G宽带相控阵波束形成器和宽带成像系统应用中具有吸引力。

A Wideband High Gain Taper Slot Antenna for 5G Millimeter-wave Imaging System Application
This paper presents a wideband coplanar waveguide (CPW) feed taper slot antenna. A microstrip-line-to-slot transition structure is used to excite the slot radiator. Wideband performance is realized by the aperiodic continuously scaled structure. The fabricated antenna prototype features a compact size of 61 × 25 × 0.16 mm3. Measurement results show this antenna achieves better than 10 dB return loss within an ultra-wideband (10–40 GHz). The measured peak gain within this band ranges from 6 to 12.5 dBi. The wideband characteristic makes this antenna attractive in 5G wideband phased-array beamformer and wideband imaging system applications.
