| description | The invention provides an external antenna, an impedance matching network parameter debugging method of the external antenna and an antenna. The external antenna comprises a controller, a first capacitor, a second capacitor, a first inductor and a transmitting antenna, the controller is connected with the transmitting antenna through the first inductor, one end of the first inductor is connected with one end of the first capacitor, the other end of the first capacitor is connected with the other end of the first inductor through the second capacitor, and the other end of the first capacitor is grounded; the controller receives a transmitting signal of a transmitting source and inputs the transmitting signal to a pi type impedance matching network for 50-ohm impedance matching, and the matched transmitting signal is transmitted through the transmitting antenna, so that the transmitting signal is subjected to 50-ohm impedance matching before being transmitted, attenuation of the transmitting signal in the transmitting process of the external antenna is reduced, transmitting power of the transmitting signal is improved through the external antenna, it can be guaranteed that signal transmitting work of the external antenna is smooth, and secondary development caused due to the fact that the signal transmitting work can not be finished is avoided. |
