Problems solved by technology

[0004] While having a common antenna solution (multi-band antenna) is great from a network point of view, from an antenna designer's point of view, there are various challenges, such as low-band radiators—often shielding Higher-band radiator (due to its large size) - will resonate at higher-band operating frequencies and degrade the antenna's higher-band radiation pattern

Abstract

An antenna apparatus and a base station are provided wherein the antenna apparatus includes a first radiator configured to radiate a low frequency signal and a second radiator configured to radiate a high frequency signal, the first radiator including at least one first stub and at least one second stub; one end of the first branch is connected to a first connection point on the first radiator, and the other end of the first branch is a free end; one end of the second branch is connected to a second connection point on the first radiator, and the other end of the second branch is a free end; the sum of the length of the first branch, the length of the second branch and the length of the first radiator between the first connection point and the second connection point is determined according to the wavelength corresponding to the predefined high frequency. The applied stubs create one or more new current paths, thus changing the resonant mode of the induced current on the low-band radiation arms at the high band.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to an antenna device and a base station. Background technique [0002] An antenna is a conversion member that can convert a guided wave on a transmission line to an electromagnetic wave in free space, or vice versa. [0003] Today, with the development of wireless communication networks, the base station antenna architecture is becoming more and more complex. The allocation of new frequency bands and striving to have a common scheme (ie, one antenna serving all frequency bands and all network generations) has resulted in densely distributed arrays of "variety-band radiators" on the base station antenna reflectors. [0004] Although from a network point of view it is very good to have a common antenna solution (multi-band antenna), from an antenna designer's point of view there are various challenges such as low-band radiators - often obscuring Higher-band r...
