Abstract

The present invention provides an antenna structure and a terminal. The antenna structure includes: a metal plate having a first surface and a second surface which are disposed opposite to each other,wherein metal plate is provided with receiving grooves which are adjacent to the first surface; spiral radiators installed in the receiving grooves which are in insulation arrangement with the metalplate, wherein each spiral radiator is provided with a feed end configured to connect with a feed source. According to the scheme, the problems are solved that a millimeter wave antenna disposed on the terminal occupies more space and does not facilitate the design challenge of miniaturization and the whole machine integration in order to achieve multi-band, large bandwidth, and high gain in the prior art .

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an antenna structure and a terminal. Background technique [0002] At present, millimeter-wave antennas mostly use antenna-in-package (AiP) technology, which integrates millimeter-wave array antennas, radio frequency integrated circuits (RFICs) and power management integrated circuits (PMICs) into one module. Wherein, the antenna units constituting the millimeter wave array are mainly patch antennas (patch), Yagi-Uda antennas (Yagi-Uda) or dipole antennas (dipole). These antenna units are relatively narrow-band antennas. For example, the relative bandwidth percentage of a conventional patch generally does not exceed 8%, but millimeter-wave frequency bands often require dual-band or multi-band and large bandwidth, which brings great impact to the antenna design. challenge. [0003] Among them, in order to meet the requirements of dual-band, multi-band, and multi-b...
