Abstract: Embodiments of this application provide an antenna apparatus and an electronic device. The antenna apparatus is provided with a non-resonant unit and a feed unit, to respectively feed a radiation unit and a non-resonant unit. Through feeding power distribution design, the non-resonant unit can assist in exciting a floor characteristic mode. In addition, since a size of the non-resonant unit is much smaller than an electrical length required for resonance of an antenna on this frequency band, the non-resonant unit does not generate a resonance curve on a resonance curve and has no resonance point, to improve radiation efficiency of the antenna without generating new resonance, so as to improve a use effect of a user.

Abstract: An array antenna is provided with a plurality of radiating patches, wherein each of the patches, operates in one frequency band along one direction and in a different frequency band along a second direction orthogonal to the first direction. The signals from each radiating patch are coupled to two delay lines, which traverse over a variable dielectric constant plate. A voltage potential is controllably applied to each delay line to change the dielectric constant of the VDC plate in the vicinity of that delay line, thereby introducing delay in signal travel. In order to isolate the voltage potential from the two orthogonal delay lines applied to each radiating patch, at least one of the delay lines is connected to a coupling patch, which capacitively couples the RF energy to the radiating patch.

Abstract: This disclosure describes techniques that enable individual antenna arrays of a base station node to transmit digital information via a plurality of frequency bands. More specifically, a remote radio unit (RRU) may include a first set of antenna arrays and a second set of antenna arrays. Each set of antenna arrays comprise antenna elements that are configured for use with different frequency bands. In this way, the RRU, via the first and second sets of antenna arrays, may be configured for simultaneous use with different frequency bands.
