摘要： An antenna assembly includes at least two active or main radiating omni-directional antenna elements arranged with at least one beam control or passive antenna element used as a reflector. The beam control antenna element(s) may have multiple reactance elements that can electrically terminate it to adjust the input or output beam pattern(s) produced by the combination of the active antenna elements and the beam control antenna element(s). More specifically, the beam control antenna element(s) may be coupled to different terminating reactances to change beam characteristics, such as the directivity and angular beamwidth. Processing may be employed to select which terminating reactance to use. Consequently, the radiator pattern of the antenna can be more easily directed towards a specific target receiver/transmitter, reduce signal-to-noise interference levels, and/or increase gain. A Multiple-Input, Multiple-Output (MIMO) processing technique may be employed to operate the antenna assembly with simultaneous beam patterns.

摘要： An antenna device and a beam direction adjustment method are provided. The antenna device includes an antenna element, a metal element, and a substrate. The antenna element and the metal element are separately disposed on the substrate at a preset distance. A ground point of the metal element is fastened on a pad of the substrate, and the ground point is on a side of the metal element close to the antenna element. A first reverse current opposite to an antenna current generated by the antenna element is obtained through coupling on the side of the metal element close to the antenna element, and a second reverse current opposite to a substrate current generated by the substrate is obtained through coupling at a lower part of the metal element that is in contact with the substrate.

摘要： A rectangular substrate provided in a radio communication terminal includes a built-in antenna and a grounded conductor functioning as a current control conductor. The antenna is placed in the vicinity of one short side of the substrate, and the current control conductor is placed in a vicinity of the other short side of the substrate. When the substrate has, for example, a half wavelength, the current control conductor changes an effective length of the substrate to reduce a high-frequency induced current generated in the substrate. Therefore, the deterioration of the antenna characteristics influenced by the human body can be prevented. The invention is applicable to the radio communication terminal having two casings movably connected by a connector.

摘要： In a compound portable terminal which supports two communication standards using different frequencies when an antenna is prepared for each communication standard, radio interference occurs in two antennas, and there is a possibility that bit errors increase. To avoid this possibility, there is a problem that two antennas need to be separated from each other as far as possible. To solve this problem, two elements are disposed in the vicinity of each other, a feeding terminal and a ground terminal are disposed in one of the elements, and a ground terminal is disposed in the other element. The other element has no feeding element. When transmission is performed from the feeding terminal, an induced current is produced in the element having no feeding terminal, and each element is excited by individual resonance frequency, and operate as antennas.
