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.

Abstract: A millimeter wave antenna device includes an antenna array, a first parasitic element and a second parasitic element. The antenna array includes m×n antennas and is disposed in an antenna area. The first parasitic element is disposed beside a first side of the antenna area. The second parasitic element is disposed beside a second side of the antenna area. None of the first parasitic element and the second parasitic element overlaps with the antenna area.

Abstract: A communication device for detecting an object includes a power module, an antenna array, a first sensor pad, a second sensor pad, and a control unit. The antenna array is excited by the power module, and is configured to provide a first beam group and a second beam group. The first sensor pad is disposed adjacent to the first side of the antenna array. A first capacitance is formed between the first sensor pad and the object. The second sensor pad is disposed adjacent to the second side of the antenna array. A second capacitance is formed between the second sensor pad and the object. The control unit controls the power module according to the first capacitance and the second capacitance, so as to selectively apply at least one power backoff operation to the first beam group and/or the second beam group.
