摘要： An antenna is described. The antenna includes a planar circular structure. The antenna also includes a radiating element located at the center of the planar circular structure. The antenna further includes one or more parasitic elements located on a contour around the radiating element. The parasitic elements are aligned in parallel direction with the radiating element. The parasitic elements protrude from the planar circular structure. The antenna includes switches separating each of the one or more parasitic elements from ground. A switch in a first position creates a short between a parasitic element and ground. A switch in a second position creates an open circuit between the parasitic element and ground.
摘要翻译： 描述天线。 天线包括平面圆形结构。 天线还包括位于平面圆形结构的中心处的辐射元件。 天线还包括位于辐射元件周围轮廓上的一个或多个寄生元件。 这些寄生元件与辐射元件平行排列。 寄生元件从平面圆形结构突出。 天线包括将一个或多个寄生元件中的每一个与地分开的开关。 第一位置的开关在寄生元件和地之间产生短路。 处于第二位置的开关在寄生元件和地之间产生开路。
