Abstract: A multi-band antenna array includes a plurality of first antennas for resonating at a first band, and a plurality of second antennas for resonating at a second band. A frequency of the second band is higher than a frequency of the first band. Locations of the plurality of first antennas project to a plurality of grid-one positions on a surface; locations of the plurality of second antennas project to a plurality of grid-two positions on the surface. Among the grid-one positions, a second grid-one position is nearest to a first grid-one position by a first distance along a first direction. Among the grid-two positions, a first grid-two position and a second grid-two position are closest two to the first grid-one position. The first and second grid-two positions are separated by a second distance along a second direction; and, the first direction and the second direction are nonparallel.

Abstract: A communication device includes an antenna, a frequency dividing circuit, and at least one variable impedance circuit. The frequency dividing circuit has a common port coupled to the antenna and at least one output port. The frequency dividing circuit is configured to divide a frequency range received from the common port into a plurality of frequency sub-ranges and output at least one of the frequency sub-ranges respectively at the output port. Each variable impedance circuit is coupled between a corresponding output port of the frequency dividing circuit and a first reference voltage. Each variable impedance circuit provides a respective variable impedance value switched between different respective impedance values.
