Indoor multi-band top-suction antenna for mobile communication

The utility model relates to an indoor multi-band top-suction antenna for mobile communication, and the operating frequency band can cover the bands of an 800 to 960 MHz and a 1710 to 2300 MHz and can be simultaneously used for the mobile communication usage of a plurality of bands of CDMAone, GSM, DCS, PCS, DECT, UMTS, IMT-2000, etc. The utility model comprises a printing type monopole radiating element, a loading metal sheet which is connected with the tail end of the radiating element and vertical with the radiating element, a circular grounding metal reflecting plate, and a micro-strip type impedance matching network which is composed of a microwave substrate and arranged on the top of the metal reflecting plate in parallel. The radiating element is vertically arranged on the top of the micro-strip impedance matching network. A rotational symmetric dielectric antenna cover is arranged on the top of the metal reflecting plate, and the radiating element, the loading metal sheet, and the micro-strip impedance matching network are enclosed in the rotational symmetric dielectric antenna cover. The utility model has the advantages of small size, beautiful appearance, low cost, and convenient installation and operation.
