Panel antenna

The invention discloses a panel antenna. The panel antenna comprises a housing serving as an antenna reflection plate as well as an emission plate and a small emission plate which serve as emitters of the antenna, wherein the small emission plate is arranged at the front end of the emission plate and is fixed to the housing through a screw; a detection apparatus is arranged in the housing; and a wiring terminal is arranged at one end of the emission plate and is connected with the detection apparatus through a signal line. Compared with a general panel antenna with the same area, the panel antenna has the advantages that in a signal set of the panel antenna, a signal transmission distance is farther, and the antenna deforms slightly during use, so that signals are stable. 本发明公开了种平板天线，包括作为天线反射板的壳体和作为天线发射极的发射板及小发射板，所述小发射板设于所述发射板的前端，并通过螺丝固定于所述壳体上，所述壳体内设有检测装置，所述发射板的端设有接线端子，所述接线端子通过信号线连接所述检测装置。本发明的平板天线的信号集中，与同样的面积的普通平板天线的相比，信号的传输距离更远，在使用过程中天线产生变形小，从而能使信号稳定。
