We have fabricated 60GHz-band models of radial line slot antennas, slot arrays using radial waveguides, in order to apply for car warning radar and wireless LAN.We have obtained stable opreration of the 60GHz-band models using a thick ground plane and hard dielectric material to keep the height of the waveguide constant all over the antenna aperture. We have proposed a novel technique to excite cylindrical TEM wave in radial waveguide through a ring slot in order to fit well with a planar RF circuit such as a signal generator.We have also proposed a single-layr feed waveguide consisting of posts to excite a plane TEM wave in a rectangular parallel plate waveguide. The waveguide can be easily fabricate by making many via holes densely and metalizing them as the posts. We have confirmend the plane TEM wave excitation in the parallel plates by experiment using a 40GHz-band model.We have fabricated a 60GHz-band model of parallel plate slot arrays, where a plane TEM wave is excited by a NRD guide. We have also developed a 60GHz digital transceiver for wireless LAN,based on the NRD guide techonology. Both-way date transmission between two compuerst can be achieved simultaneously.

为了应用于汽车报警雷达和无线局域网，我们制作了60GHz波段的径向线缝隙天线模型，即径向波导缝隙阵列，我们使用厚的接地层和硬介质材料来保持波导高度在整个天线口径范围内保持恒定，从而获得了稳定的工作。本文提出了一种在径向波导中通过环形缝隙激励圆柱形TEM波的新技术，以适应平面射频电路（如信号发生器），并提出了一种在矩形平行板波导中激励平面TEM波的单层柱形馈电波导。通过密集地制造许多通孔并将它们金属化作为柱，可以容易地制造波导。用40GHz的平行平板模型实验证实了平面TEM波在平行平板中的激发，并制作了60GHz的平行平板缝隙阵列模型，其中平面TEM波由NRD波导激发。我们还开发了一个60GHz的无线局域网数字收发器，基于NRD指南技术。可同时实现两台计算机之间的双向数据传输。
