    • In a broadband antenna unit including a ground plate, an antenna element disposed in the vicinity of an end of the ground plate, and a dielectric substrate for mounting the antenna element therein, the antenna element includes a folded plate-shaped monopole antenna portion having a U-shape in cross section, a first conductive element extending from a first location of the folded plate-shaped monopole antenna portion, and a second conductive element extending from a second location of the folded plate-shaped monopole antenna portion. The antenna element is disposed on the side of one side edge of the ground plate. The broadband antenna unit has a feeding point between the ground plate and the antenna element that is disposed at a feeding position apart from the one side by a predetermined distance.
    • 在包括接地板的宽带天线单元中,设置在接地板的端部附近的天线元件和用于将天线元件安装在其中的电介质基板,天线元件包括折叠的板状单极天线部分,其具有 U形截面,从折叠板状单极天线部分的第一位置延伸的第一导电元件和从折叠板状单极天线部分的第二位置延伸的第二导电元件。 天线元件设置在接地板的一个侧边缘的一侧。 宽带天线单元在接地板和天线元件之间具有馈送点,该馈电点设置在远离一侧的馈送位置预定距离处。
