    • Disclosed herein is a dielectric waveguide antenna including: a dielectric waveguide transmitting a signal applied from a power feeder; a dielectric waveguide radiator radiating the signal transmitted from the dielectric waveguide to the air through a first aperture; and a matching unit formed in a portion of the dielectric waveguide and controlling a serial reactance and a parallel reactance to thereby perform impedance matching between the dielectric waveguide radiator and the air, in order to reduce reflection generated in the first aperture during the radiation of the signal through the first aperture. Reflection in the aperture is reduced through the matching unit having various structures, thereby making it possible to improve characteristics of the dielectric waveguide antenna.

    • An antenna comprises a first conductive layer, a second conductive layer and an LC resonance circuit. The first conductive layer has plural elements and is disposed adjacently to each other. The second conductive layer is disposed at a predetermined distance from the first conductive layer via a dielectric substrate. The LC resonance circuit comprises connection for electrically connecting the elements and the second conductive layer. The LC resonance circuit takes a resonance state in which impedance becomes high in the operating frequency of the antenna. Of the plural elements, a power feeding section is provided in each of any two adjacent elements. Power is fed to the power feeding sections during transmission so that signals of the operating frequency are opposite in phase, and signals of the operating frequency inputted to the antenna are outputted in opposite phase from the power feeding sections during reception.
    • 天线包括第一导电层,第二导电层和LC谐振电路。 第一导电层具有多个元件并且彼此相邻地设置。 第二导电层经由电介质基板与第一导电层隔开预定距离。 LC谐振电路包括用于电连接元件和第二导电层的连接。 LC谐振电路采用谐振状态,其中天线的工作频率中阻抗变高。 在多个元件中,在任何两个相邻元件中的每一个中设置供电部。 在发送期间将功率馈送到馈电部分,使得工作频率的信号相位相反,并且在接收期间输入到天线的工作频率的信号与馈电部分以相反的相位输出。
