Abstract

The embodiment of the invention discloses an antenna device and electronic equipment. The antenna device comprises a non-metal dielectric plate, an antenna and a plurality of electromagnetic band gapunits, wherein the antenna and the plurality of electromagnetic band gap units are arranged on the non-metal dielectric plate, and the plurality of electromagnetic band gap units are arranged around the antenna according to a first array mode; and the electromagnetic band gap units are used for suppressing surface electromagnetic wave transmission of the non-metal dielectric plate. Therefore, by arranging the electromagnetic band gap unit array around the antenna, for all incoming wave directions and antenna polarization directions, the electromagnetic band gap unit array can inhibit surface electromagnetic wave transmission of the non-metal dielectric plate and eliminate interference of surface electromagnetic waves of the non-metal dielectric plate on the antenna, so that detection of anarrival angle is irrelevant to antenna polarization, then the detection error caused by different antenna polarizations is eliminated, and the detection precision of the arrival angle is improved.

Description

technical field [0001] The present application relates to communication technology, and in particular to an antenna device and electronic equipment. Background technique [0002] Existing positioning technologies generally identify the direction of arrival of electromagnetic waves, that is, the angle of arrival, based on the phase difference of received signals between antennas. However, since the environmental loading conditions will affect the detection accuracy of the angle of arrival, it is necessary to correct the angle of arrival according to the current environmental loading conditions. Thus, the detection accuracy of the angle of arrival is ensured. [0003] However, this scheme of correcting the angle of arrival according to the environmental loading conditions needs to pre-store the phase difference curves under various loading environments, so as to identify the loading environment according to the phase difference, but this method has a large misjudgment, and can...
