Abstract: 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.

Abstract: A dual-band antenna and a wireless communications device, where the dual-band antenna includes a first antenna arranged on a first printed circuit board (PCB), a second antenna arranged on a second PCB, and a reflection panel. An operating frequency band of the first antenna is a first frequency band. An operating frequency band of the second antenna is a second frequency band. The first frequency band is higher than the second frequency band. The second PCB is disposed between the first PCB and the reflection panel. The reflection panel includes an artificial magnetic conductor. A resonant frequency band of the artificial magnetic conductor includes the second frequency band. The first frequency band is outside the resonant frequency band. The dual-band antenna has a small size.

Abstract: An antenna assembly and a wireless access device are provided. The antenna assembly includes a first antenna part and a second antenna part. A first port, a first radiation arm, a first ground point, and a first bearing part of a bearing plate form the first antenna part. A second port, a second radiation arm, a second ground point, and a second bearing part of the bearing plate form the second antenna part. The first radiation arm is configured to radiate a radio frequency signal received by the first port, and transmit a received radio frequency signal to the first port. The second radiation arm is configured to radiate a radio frequency signal received by the second port, and transmit a received radio frequency signal to the second port. An anti-interference path passing through the bearing plate exists between the first port and the second port.
