摘要
提出了一种用于超宽带通信系统的扇形天线[j]。近藤等，2004 [H]。Nakano等人，2006]。扇形天线为卡式天线，其辐射元件与接地板在同一平面上。该卡式结构便于在个人计算机或移动电话手持设备内部的PC卡设备中使用扇形天线。随后，采用椭圆天线，其中[T]中的扇形单元。近藤等，2004 [H]。Nakano et al.， 2006]被椭圆形导电环取代，并与扇形天线的辐射特性进行了比较。[j]。Nakano等人，2005]。发现椭圆型和扇形天线具有相似的天线特性。
A folded elliptical antenna with a stop band characteristic
A fan-shaped antenna has been proposed for UWB communications systems [T. Kondo et al., 2004][H. Nakano et al., 2006]. The fan-shaped antenna is a card-type antenna, where the radiation element and the ground plate lie in the same plane. The card-type structure facilitates the use of the fan-shaped antenna in PC card devices for personal computers or inside mobile phone handsets. Subsequently, an elliptical antenna, where the fan-shaped element in [T. Kondo et al., 2004][H. Nakano et al., 2006] is replaced with an elliptically shaped conducting ring, has been investigated and its radiation characteristics have been compared to those of the fan-shaped antenna [S. Hattori et al., 2005] [H. Nakano et al., 2005]. It is found that the elliptical and fan-shaped antennas have similar antenna characteristics.
