Abstract: The present invention relates to the communications field, and in particular, to an antenna system. The antenna system includes: a transmit antenna, a receive antenna, a radome above the transmit antenna and the receive antenna, and a reflector within the radome, where a signal received by the receive antenna after a transmitted signal of the transmit antenna is reflected by the reflector offsets an intra-frequency interference signal generated because the transmitted signal of the transmit antenna is directly received by the receive antenna. As a result, according to the embodiments of the present invention, the intra-frequency interference signal of the transmit antenna to the receive antenna may be eliminated without increasing the number of antennas and a distance between antennas.

Abstract: The present invention relates to an antenna, which includes a feeding part and a radiating part. By using the feeding part and the radiating part that are perpendicular to each other and use dielectric substrates, not only a volume of a normal radiation antenna is reduced, but also a substrate integrated waveguide directly radiates energy outwards, thereby improving operating bandwidth of the antenna.
