摘要： An antenna apparatus and a radio communications device are disclosed. The antenna apparatus includes a circuit board and a plurality of radiators. The plurality of radiators are all located on the circuit board. The plurality of radiators form at least one radiator array. Each radiator array includes a first column of radiators and a second column of radiators. In each radiator array, a polarization direction of the first column of radiators is perpendicular to a polarization direction of the second column of radiators, and radiators in the first column of radiators and radiators in the second column of radiators do not overlap. An end of each radiator in the first column of radiators points to a target location range of an adjacent radiator in the second column of radiators.

摘要： A quasi-omnidirectional antenna and a signal transceiver are provided. The quasi-omnidirectional antenna includes a housing having a metal rear cover facing a boundary of an installation area and a front cover disposed opposite to the metal rear cover. A forward facing antenna is disposed in the housing and is configured to radiate in a direction away from the metal rear cover. First and second side antennas are disposed in the housing, with the first side antenna and the second side antenna being oppositely disposed on two sides of the forward facing antenna. Each side antenna includes a metallic ground that is signal-connected to the metal rear cover. An overlapping area extends between the radiation area of each side antenna and a radiation area of the forward facing antenna.
