Abstract: An antenna structure includes four antenna arrays spaced apart from each other. Each of the four antenna arrays has four antennas. A first phase difference between any two adjacent ones of the four antennas is 90 degrees, so that the four antennas can jointly generate a first circular polarization. The four antenna arrays have a common center point, one of the four antennas of each of the four antenna arrays adjacent to the common center point is defined as a shared antenna, and the four shared antennas jointly form a shared antenna array. A second phase difference between any two adjacent ones of the four shared antennas is 90 degrees, so that the four shared antennas can jointly generate a second circular polarization that has a same rotation direction as the first circular polarization.

Abstract: An antenna structure includes a first conductor, a high-frequency blocking unit, and a second conductor. The first conductor includes a feeding segment, a coupling segment spaced apart from the feeding segment, and a DC blocking unit connected between the feeding segment and the coupling segment. The high-frequency blocking unit is connected to the coupling segment. The second conductor is spaced apart from the first conductor and couples with the coupling segment. An end of the second conductor is connected to a ground, and the second conductor is provided without connecting any capacitance member and any inductance member. The coupling segment is used as a capacitor electrode for detecting an external object. When the coupling segment is in a capacitor electrode mode, a capacitance value between the coupling segment and the external object is variable according to a distance between the coupling segment and the external object.

Abstract: A dual-polarized antenna structure is provided. The dual-polarized antenna structure includes an insulating substrate, two first antennas, two second antennas, a coupling unit, and two feeding points. The two first antennas are disposed on two sides of the insulating substrate, respectively. The two second antennas are disposed on the two sides of the insulating substrate, respectively. Each of the two second antennas includes two sub-antennas. In any one of the two sides of the insulating substrate, a region defined by orthogonally projecting two sub-middle segments of the two sub-antennas onto another one of the two sides of the insulating substrate overlaps with a main middle segment of the first antenna.

Abstract: A mobile communication device includes an assembly, an antenna module disposed on the assembly, and a metal cover detachably fixed on the assembly. The antenna module has an internal segment and an external segment connected to the internal segment. The internal segment is arranged in a space surrounded by the metal cover and the assembly and is entirely shielded by the metal cover in a thickness direction. The external segment is disposed on a short side surface of the assembly and is arranged outside the space. The external segment does not contact the metal cover. Thus, the metal cover of the mobile communication device of the instant disclosure can be provided without extra design.

Abstract: A three-dimensional antenna structure is applicable to a transmission frequency band, and includes an insulating carrier, an M number of first antennas, an M number of microstrip lines, a second antenna, and a grounding element. The M microstrip lines are electrically coupled to the M first antennas. The second antenna is electrically coupled to the M first antennas through a connection point of each of the M microstrip lines, and has an M−1 number of line segments. Any end of each of the M−1 line segments correspond in position to one of the connection points of the M microstrip lines. A length of each of the M−1 line segments is 1/M times a wavelength corresponding to a center frequency of the transmission frequency band. The grounding element is electrically coupled to the M first antennas through the M microstrip lines.

Abstract: A low-frequency antenna module includes two switching units, a first matching circuit, a second matching circuit, and a low-frequency antenna. Each of the two switching units includes an electrical connection point, a first switching point, and a second switching point. The first matching circuit is electrically connected to the two first switching points, the second matching circuit is electrically connected to the two second switching points, and the low-frequency antenna is electrically connected to one of the two electrical connection points. The two switching units are synchronously operated to electrically connect the two electrical connection points to the two first switching points or to the two second switching points. Thus, the low-frequency antenna can be applied to match the first matching circuit in a first low-frequency band or the second matching circuit in a second low-frequency band different from the first low-frequency band.
