提出了一种用于毫米波无线通信的微带-槽线过渡渐变槽天线。两个具有不同孔径宽度和长度的天线被制造在Teflon基板上（εr = 2.2，t = 10 mils），并且在55-63 GHz下，对于3.5 mm和1 mm的孔径，测量的S11 −8 dB分别具有11 dB和7 dB的增益。为了验证其在便携式毫米波系统中的性能，在天线的上方和下方放置了两个金属屏蔽层。结果表明，TSA保持良好的阻抗匹配和增益与金属平面高度为1-3毫米，取决于孔径。一个四元TSA阵列也证明了开关波束系统。
A tapered-slot antenna (TSA) with microstrip-to-slotline transition is demonstrated for millimeter-wave wireless communications. Two antennas with different aperture widths and lengths are fabricated on a Teflon substrate (εr = 2.2, t = 10 mils), and result in a measured S11 < −8 dB with a gain of 11 dB and 7 dB at 55–63 GHz for an aperture of 3.5 mm and 1 mm, respectively. To validate its performance inside portable mm-wave systems, two metal shielding planes are placed above and below the antennas. The results show that the TSAs maintain good impedance matching and gain with a metal plane height of 1–3 mm, depending on the aperture. A four-element TSA array is also demonstrated for switched-beam systems.
