(1) A novel quasi-optical antenna mixer has been developed. The antenna mixer consists of a coplanar waveguide fed dual-frequency microstrip antenna and Schottky-barrier diode connected to the end of the guide. A novel beam scanning system in which the phase shifter is not used has been realized using the antenna mixer.(2) An image NRD guide (iNRDG) has been proposed as a low-loss guide in the millimeter-wave band. A transverse slot cut on the image plate of the iNRDG has been developed as a novel millimeter-wave antenna. To design the array of the transverse slot, an analysis and a measurement method of the normalized impedance has been developed.(3) A novel coaxial feed technique of the image dielectric waveguide (DIL) has been proposed. In addition, a transition between DIL and iNRDG has been investigated. The validity of the proposals has been confirmed using experimental results and FDTD analysis.(4) Behavior of parallel plate mode in a triplate-type slot-coupled microstrip antenna has been clarified through the use of the spectral domain moment method. A novel suppression technique of the parallel plate mode has been also investigated.(5) A novel printed slot array antenna, in which a backward excitation is employed, has been developed as an element of sector antenna for millimeter-wave wireless LAN systems. A rigorous design technique of the array antenna has been investigated. In the technique, the spectral domain moment method is used.

(1)研制了一种新型准光天线混频器。天线混频器由共面波导馈电双频微带天线和连接到波导末端的肖特基势垒二极管组成。利用天线混频器实现了一种不使用移相器的新型波束扫描系统。(2)镜像NRD波导（iNRDG）已被提出作为毫米波段的低损耗波导。一个横向开槽上的图像板的iNRDG已被开发作为一种新型的毫米波天线。为了设计横向缝隙天线阵，提出了一种归一化阻抗的分析和测量方法。(3)提出了一种新型镜像介质波导同轴馈电技术。此外，还研究了DIL和iNRDG之间的过渡。实验结果和时域有限差分法分析证实了该方法的有效性。(4)本文用谱域矩量法研究了三片式缝隙耦合微带天线中平行板模的特性。本文还研究了一种新的平行板模抑制技术。(5)提出了一种新型的印刷缝隙阵列天线，该天线采用后向激励，可作为毫米波无线局域网系统的扇形天线单元。研究了阵列天线的严格设计方法。该方法采用谱域矩量法。
