Abstract
A reconfigurable radiation pattern loop antenna is presented in this paper. The loop antenna operates at 2.4 GHz (WLAN/ Bluetooth /LTE/UMTS) having an omnidirectional radiation pattern in the antenna plane. The reconfigurability is achieved using; primary loop antenna that is surrounded by secondary ones which are used to cancel the current and hence the radiation pattern in their direction. Accordingly, the radiation pattern can be altered from an omnidirectional to a directional one by controlling the secondary antennas.
提出了一种可重构辐射方向图环路天线。环形天线工作在2.4 GHz (WLAN/ Bluetooth /LTE/UMTS)，在天线平面上具有全向辐射模式。可重构性通过使用;主环路天线被次级环路天线包围，次级环路天线用来抵消电流，从而抵消它们方向上的辐射方向图。因此，可以通过控制次级天线将辐射方向图从全向方向图改变为定向方向图。
