Problems solved by technology

In such a system, both the antenna and the transceiver need an external matching network to match the feeder, which makes the entire system bulky and heavy, especially the loss caused by the feeder and matching network will greatly reduce the transmission of the signal efficiency

Abstract

The invention discloses an FDD antenna based on a dual-mode resonator. The FDD antenna comprises a square patch with a square groove, a stacked parasitic square patch, a first short-circuit patch and a second short-circuit patch loaded on the inner edge of the square patch, an emission channel feed probe, a reception channel feed probe, a reflection floor, an emission port, a reception port, an emission channel feed network, and a reception channel feed network. The square patch is printed on the top surface of a middle medium substrate, the parasitic square patch is printed on the top surface of an upper medium substrate, the reflection floor is printed on the top surface of a lower medium substrate, and the emission channel feed network and the reception channel feed network are printed on the bottom surface of the lower medium substrate. Designed is the antenna serving as a feed network and having a frequency division duplex function through induction of a dual-mode resonator. The antenna enables emission and reception to be conducted at the same time, and electromagnetic waves for emission and reception by the antenna are linearly polarized electromagnetic waves.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an FDD antenna based on a dual-mode resonator. Background technique [0002] As a device for transmitting and receiving electromagnetic waves, an antenna is an indispensable key component in a wireless communication system. The antenna itself is reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. In the early wireless communication systems, the antenna needs to be raised by a bracket to obtain a long communication distance. Due to the large volume and weight of the wireless transceiver, in order to reduce the weight of the elevated antenna, the antenna and the transceiver are usually separated. Such as radio frequency switch, circulator, directional coupler and duplexer, etc. to separate the signal transmitted to the transmit channel of the antenna and the signal of the receive channel received by the antenna....
