Double polarized antenna system for base station of wireless telecommunication system

摘要

The antenna system includes several orthogonally placed microstrip lines and several parasitic coupling elements. A feeder network is coupled to the microstrip lines which receive electromagnetic signals. A board part is provided which is covered with a thin layer of conductive material. An emitter is provided near the board part. The electromagnetic signals are coupled through the board part and excite the emitter which generates electromagnetic fields. The electromagnetic fields generate currents in the parasitic coupling strips which generate second electromagnetic fields which cancel the first electromagnetic fields. Independent claims are also included for the following: (1) a method for receiving and transmitting electromagnetic signals; (2) a double polarized antenna with orthogonal pairs of microstrip lines of which the first microstrip line is provided in two sections which are connected via a bridge.
