    • In a transceiver, on a top surface of a rectangular plate-shaped substrate, transmission radiating elements and receiving radiating elements are provided. The transmission radiating elements extend in the horizontal or lateral direction from the center of the substrate. The receiving radiating elements extend in the vertical or longitudinal direction from the center of the substrate. Inductors included in a matching feeding element are individually electromagnetically coupled to transmission-side feeding points that are inner end portions of the transmission radiating elements and receiving-side feeding points that are inner end portions of the receiving radiating elements. A transmission signal is transmitted with a wave polarized in the horizontal or lateral direction, and a signal having a vertical or longitudinal polarization direction is received.
    • 在收发器中,在矩形板状基板的顶表面上,设置有传输辐射元件和接收辐射元件。 透射辐射元件从基板的中心沿水平或横向方向延伸。 接收辐射元件从基板的中心在垂直或纵向方向上延伸。 包含在匹配馈送元件中的电感器单独地电磁耦合到作为接收辐射元件的内端部的发送辐射元件和接收侧馈电点的内端部的发送侧馈电点。 发送信号以水平方向或横向偏振的波发送,并且接收具有垂直或纵向偏振方向的信号。
