Integrated antenna structure with linear polarization emission in arbitrary polarization direction capability

Abstract

An integrated antenna structure with linear polarization emission in arbitrary polarization direction capacity is provided. The integrated antenna structure includes a radiator, a first filter, a second filter and a 90-degree hybrid coupler. The radiator, a first filter and the 90-degree hybrid coupler are stacked in sequence. The radiator includes a first radiation part and a second radiation part. The first filter is coupling connected to the first radiation part. The second filter is coupling connected to the second radiation part. The 90-degree hybrid coupler is electrically connected to the first filter. The 90-degree hybrid coupler includes a first input terminal, a second input terminal, a first output terminal and a second output terminal. In response to a first signal and a second signal being fed into the first input terminal and the second input terminal respectively, the radiator emits a linear polarization signal according to the first signal and the second signal.
