辐射状的

At present, the wireless devices in general to bring the whole antenna, omni-directional radio antenna to the antenna axis, was "donut"-shaped radiation field; directional antenna is highly directional, in the small angle of radiation is totally outside the scope of signals ; the use of removable external antenna equipment can gain antenna, the antenna can not increase in the case of radiated power to increase communication distance.

目前的无线设备一般自带全向天线，全向天线电波以天线为轴，呈"面包圈"状向外辐射；定向天线具有极强的方向性，在小角度的辐射范围外是完全没有信号的；使用可拆卸天线的设备可以外接增益天线，可以在不增加天线辐射功率的情况下增加通讯距离。
