    Abstract: An antenna with swappable and selective radiation direction includes a first arm, a second arm electrically connected to the first arm, a third arm is electrically connected to the first arm, a first impedance tuning circuit coupled to the second arm for connecting the second arm to a ground or a first matching component according to a control signal, and a second impedance tuning circuit coupled to the third arm for connecting the third arm to the ground or a second matching component according to the control signal. By tuning impedance of the antenna, the antenna operates in a first mode corresponding to a first radiation direction or a second mode corresponding to a second radiation direction.

    Abstract: The invention provides an antenna module of improved performances; the antenna module may comprise a plurality of first antennas for signaling at a first band, and a plurality of second antennas for signaling at a second band different from the first band. Each said first antenna may comprise a main radiator which resonates at a mode-one frequency and a mode-two frequency different from the mode-one frequency; and the main radiator may be configured such that the mode-one frequency may be in the first band, and the mode-two frequency may not be in the first band and the second band.

    Abstract: The invention provides an antenna for multi-broadband and multi-polarization communication, which may include a plurality of radiators configured to jointly function as one or more dipoles, and a plurality of parasitic elements. Each radiator may be configured to contribute to resonances at two or more nonoverlapping bands, and may comprise an arm and a ground wall connecting the arm and a ground plane. The arm may comprise an arm plate and a folded arm. The ground wall may comprise a meandering portion causing a distance between the arm and the ground plane to be shorter than a length of a current conduction path along the ground wall between the arm and the ground plane. On a geometric reference surface, a projection of each parasitic element may extend between two gaps which clamp a projection of an associated one of the radiators.

    Abstract: A multi-antenna system is provided. The multi-antenna system includes a first antenna, a second antenna, a tunable circuit, and a frequency-divisional circuit. The first antenna is utilized to implement signals of a first frequency band. The second antenna is utilized to implement signals of a second frequency band. The second antenna is different from the first antenna, and frequencies of the second frequency band are greater than frequencies of the first frequency band. The tunable circuit is utilized to switch the signals of the first frequency band. The frequency-divisional circuit is utilized to suppress harmonics caused by the tunable circuit.
