Abstract

The invention provides a miniaturized dual-frequency nested antenna. A through hole is formed in the middle part of a low-frequency dielectric substrate and thus a low-frequency antenna has an annularhollow structure and a high-frequency antenna is arranged in the annular structure, so that the positions of the low-frequency antenna and the high-frequency antenna are overlapped partially and thusthe horizontal dimension is reduced. Moreover, vertical side plates are arranged around the low-frequency dielectric substrate and the surface of the low-frequency dielectric substrate is covered bya horizontal radiation metal patch, so that the horizontal dimension of the low-frequency antenna is reduced and the radiation surface of the low-frequency antenna is increased. Furthermore, verticalradiation metal patches with L-shaped grooves are arranged at the peripheral directions of the side plates and the L-shaped grooves play a role of optimizing the bandwidth. Therefore, the wireless signal transceiving system and the miniaturized dual-frequency nested antenna have the following beneficial effects: the frequency band requirement is met and the size is reduced effectively.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a miniaturized dual-frequency nested antenna. Background technique [0002] Under the new-generation mobile communication system, multiple systems and multiple systems coexist. Therefore, antennas that coexist in multiple frequency bands have become the main mode of current base station antennas. With the continuous upgrading of communication systems, new frequency bands are required to be configured. Therefore, it is necessary to match the base station antenna suitable for the new frequency band. For example, with the development and maturity of Wimax, LTE and other technologies, it is necessary to expand new frequency bands (ultra-wideband), and then it is necessary to match the ultra-wide frequency band (806MHz-960MHz) and ultra-wide frequency band (1710MHz-2700MHz) composed of radiating oscillators. Broadband base station antenna. [0003] At present, the r...
