摘要： A quadri-polarization diversity antenna system is disclosed.
According to embodiments of the present disclosure, an antenna system includes an antenna array including columns of first dual-polarized antenna units arranged on a first plane of an antenna panel and columns of second dual-polarized antenna units arranged on a second plane of the antenna panel. The first plane and the second plane form an obtuse angle with each other. The columns of the first dual-polarized antenna units are used to form a first beam with +/-45 ° polarizations, and the columns of the second dual-polarized antenna units are used to form a second beam with 0°/90° polarizations.

摘要： A radar device for automotive applications comprises a radar circuit configured to process a radar signal that has a first signal portion and a second signal portion, wherein the first signal portion occupies a first frequency band and the second signal portion occupies a second frequency band that is separate from the first frequency band. An antenna device of the radar device comprises a first and second antenna element that are both coupled to a common signal port of the radar circuit and the radar device is configured to route both the first signal portion and the second signal portion via the common signal port between the radar circuit and the antenna device. The antenna device is a frequency selective antenna device that transduces the first signal portion via the first antenna element and not via the second antenna element and that transduces the second signal portion at least via the second antenna element.

摘要： This application provides a microstrip antenna and an electronic device. The microstrip antenna includes a radiator and a first feed and a second feed that are configured to feed a radio frequency signal, and a first feedpoint and two second feedpoints are disposed on the radiator. The first feedpoint is located at a central position of the radiator, and the first feedpoint is electrically connected to the first feed, and is configured to feed a radio frequency signal into the radiator, to excite the radiator to generate a TM 02 mode. The two second feedpoints deviate from the central position of the radiator and are spaced apart from the first feedpoint. The second feed is electrically connected to the second feedpoints through an adjustment circuit. The second feedpoints are configured to feed a radio frequency signal into the radiator, and the second feedpoints excite, by using the adjustment circuit, the radiator to generate a TM 10 mode, so that the radiator has performance of a dual-microstrip antenna. The microstrip antenna provided in this application resolves a technical problem of a high SAR value of an existing microstrip antenna.
