车载用天线装置
摘要：
一种车载用天线装置，通过在基板上以导体图案设置阵列天线及传送线路而提供一种高增益且低成本的车载用直线极化波阵列天线装置。具备将设于电介质基板(20)的基于导体图案的多个偶极天线(31)排列而成的偶极天线阵列(30)、和设于电介质基板(20)的基于导体图案的平行双线的传送线路(40)，利用传送线路(40)向各偶极天线(31)供电。平行双线的传送线路(40)具有一对导体图案夹着电介质基板(20)而相对的结构。
摘要（英）：

Provided is an on-vehicle linear polarization array antenna apparatus that is low-cost and has a high gain, by forming an array antenna and a transmission line in conductor patterns on a substrate. The present invention is provided with: a dipole antenna array 30 in which a plurality of dipole antennas 31 formed by the conductor patterns provided to a dielectric substrate 20 are arranged; and two parallel transmission lines 40 formed by the conductor patterns provided to the dielectric substrate 20, wherein power is supplied to the dipole antennas 31 through the transmission lines 40. The two parallel transmission lines 40 have a structure in which the dielectric substrate 20 is interposed between a pair of opposing conductor patterns.
