The invention discloses an antenna device, and the device comprises a reflection wave-absorbing structure, a first antenna array, a second antenna array, a first shielding plate and a second shielding plate; the first antenna array is arranged on the first shielding plate, and the second antenna array is arranged on the second shielding plate; the included angle formed by two vectors with the maximum radiation direction of the first antenna array and the second antenna array as the direction is not smaller than 90 degrees and not larger than 180 degrees, and the reflection wave-absorbing structure is arranged on the first shielding plate and / or the second shielding plate and used for reflecting and absorbing electromagnetic waves. Through the scheme provided by the invention, surface electromagnetic waves can be reflected and absorbed on a surface electromagnetic wave coupling path, and effective attenuation of coupled electromagnetic waves is realized, so that the isolation degree between two antenna arrays is remarkably improved.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to an antenna device. Background technique [0002] Integrated access and backhaul links (IAB) is one of the vigorously developed solutions for 5th generation (5G) network construction in order to obtain higher coverage capabilities and improve resource utilization. Since the transmitter (transmitter, TX) and the receiver (receiver, RX) work at the same site, high transceiver isolation is a necessary condition to reduce interference and ensure the quality of access and return signals. Especially in the same-frequency full-duplex mode, the spectrum utilization rate is higher, and the requirements for isolation are more stringent. [0003] The isolation can be achieved mainly by improving the isolation of the antenna array and canceling in the digital domain. However, due to the limited ability of digital cancellation and the high cost, how to greatly improve th...
