A multi-frequency antenna includes a first antenna element, a second antenna element, a connection element, a third antenna element and a shorted element. The connection element is connected between the first antenna element and a neighborhood portion of the third antenna element. A feeding point is located in or nearby a first junction between the connection element and the first antenna element or located in the connection element. The shorted element is connected between the second antenna element and the grounding plane. The shorted element extends from a second junction between the second antenna element and the third antenna element to the grounding plane. The first conductive path that extends from the feeding point to the other end of the shorted element is substantially equal to a second conductive length that extends from the feeding point to the free end of the first antenna element.

Multi-frequency antenna

An antenna array has a ground plane, a plurality of spacers, a radiating patch array and a feeding member. The spacers are mounted on the ground plane. The radiating patch array is mounted on the spacers, is separated from the ground plane at an interval and has three pairs of radiating patches. Each radiating patch is parallel to the ground plane and has a sub radiating patch formed on and inclined away from the ground plane. The inclined sub radiating patches and the interval increase gain of the antenna array.

Antenna array

An antenna array unit is provided by the present invention. The antenna array unit includes: a ground, a feeder cable, a first signal feeding member, a plurality of second signal feeding members, a plurality of third signal feeding members, a plurality of first rectangular radiating members and a plurality of second rectangular radiating members. The first rectangular radiating members have first and second non-radiating sides, two radiating sides able to generate a coupling effect with a radiating side adjacent thereto. The second rectangular radiating members have first and second non-radiating sides, two radiating sides and able to generate a coupling effect with a radiating side adjacent thereto. The present invention is characterized in that at least one current disturbing member is formed at each non-radiating second side of the plurality of the first and the second rectangular radiating members and adjacent to the nearest radiating side generating the coupling effect.
