    摘要： A multiband base station antenna having improved beamwidth is disclosed. The disclosed antenna comprises: a reflective plate; a plurality of first low-band radiators arranged on the reflective plate along a first column; a plurality of second low-band radiators arranged on the reflective plate along a second column, which is parallel to the first column and is spaced from the first column; a plurality of high-band radiators arranged on the reflective plate; and a plurality of vertical choke members arranged, between the first column and the second column, in the direction parallel to that of the first column and the second column, wherein the vertical choke members comprise a first substrate, a meander line is formed on the first substrate, and a metal line is formed under the first substrate. According to the disclosed antenna, beamwidth distortion of each radiator, caused by interference between the radiators, can be prevented, and proper isolation characteristics between the radiators can be ensured.

    摘要： An antenna device includes a ground electrode, a feed element, and a parasitic element. The ground electrode has a substantially non-square rectangular plane shape that includes a first side extending in a first direction and a second side extending in a second direction orthogonal to the first direction. The feed element has a substantially rectangular plane shape and is formed in such a way that each side of the feed element becomes parallel to the first direction or the second direction. The parasitic element is formed in such a manner as to face a side of the feed element parallel to the first side. The feed element is configured to radiate a first polarized wave that excites in the first direction and a second polarized wave that excites in the second direction. The length of the first side is longer than the length of the second side.

    摘要： An antenna apparatus includes an antenna, a first matching circuit and a second matching circuit, which are connected to the antenna, and an antenna switching apparatus, which is connected to the first matching circuit and the second matching circuit. Within the same time, only one of the first matching circuit and the second matching circuit is in operation. Operating frequency-band signals of the first matching circuit and the second matching circuit on the antenna are switched by the antenna switching apparatus, so as to be used at staggered times, thereby ensuring that operating frequency-band signals of the first matching circuit and the second matching circuit can be normally used in different scenarios, and effectively improving a performance of the antenna.
