Full-duplex antenna and mobile terminal
First Claim
1. A full-duplex antenna, comprising:
- a receive antenna;
a first transmit antenna disposed on a first side of the receive antenna, wherein the first transmit antenna is a directional antenna and wherein a reverse direction of a main lobe of a radiation pattern of the first transmit antenna points to the receive antenna; and
a second transmit antenna disposed on a second side of the receive antenna, the second side opposite the first side, wherein a distance between the second transmit antenna and the receive antenna is equal to a distance between the first transmit antenna and the receive antenna, wherein the second transmit antenna is a directional antenna, and wherein a reverse direction of a main lobe of a radiation pattern of the second transmit antenna points to the receive antenna;
wherein a first polarization direction in which the receive antenna receives a signal transmitted by the first transmit antenna and a second polarization direction in which the receive antenna receives a signal transmitted by the second transmit antenna are perpendicular to each other.

Abstract
A full-duplex antenna includes a receive antenna, which is an omnidirectional antenna. A first transmit antenna is disposed on one side of the receive antenna and is a directional antenna. A reverse direction of a main lobe of a radiation pattern of the first transmit antenna points to the receive antenna. A second transmit antenna is disposed on the other side of the receive antenna. A distance between the second transmit antenna and the receive antenna is equal to a distance between the first transmit antenna and the receive antenna. The second transmit antenna is a directional antenna, and a reverse direction of a main lobe of a radiation pattern of the second transmit antenna points to the receive antenna.
