Embodiment Construction
[0031] Embodiments of the present invention will be described in detail below in conjunction with examples.
[0032] The radiating unit of the present invention uses the Vivaldi antenna principle, such as figure 1 As shown, there are gradient gap slots 3 for transmitting and receiving radiation signals at its four corners, two gradient gap slots distributed diagonally form a group, and two groups of gradient gap slots are arranged orthogonally. Folding along the dotted line in the figure reduces the occupied horizontal area and reduces the aperture of the radiation unit, which is 0.3-0.4 times the working wavelength.
[0033] figure 2 yes figure 1 The radiating unit is deformed after being partially folded along the dotted line. The radiating unit has a bowl-shaped structure. Edge 2, between two adjacent folded edges 2 is a gradual gap groove 3.
[0034] Two groups of orthogonally arranged gradient gap slots are respectively fed by two feed units 4, and feed PCB boards ca...

The invention discloses a communication antenna and a radiation unit thereof. Gradient gap grooves used for transmitting and receiving radiation signals are formed in four corners of the radiation unit, the two gradient gap grooves which are diagonally distributed are in a group, and the two groups of gradient gap grooves are orthogonal arranged and fed by means of two feeding units, the central part of the radiation unit is a flat central platform, and four sides of the radiation unit are turned up to the same side to form folded edges. The communication antenna comprises a reflecting plate and the radiation unit arranged on the reflecting plate and operating at a low frequency, wherein a high-frequency radiation element is arranged on the central platform of the radiation unit. The radiation unit has the advantages of small aperture and light weight, can significantly reduce the size of the antenna, can ensure the radiation performance index of the antenna and meets the needs of customers. The communication antenna and the radiation unit thereof are applied to a multi-frequency antenna, have small influence on a high-frequency oscillator, and are especially suitable for a multi-frequency base station antenna with a low-frequency unit and a high-frequency unit arranged in a nested array.
Description
technical field [0001] The invention relates to a communication antenna, in particular to a bowl-shaped small-diameter radiation unit and a communication antenna using the radiation unit. Background technique [0002] The radiation unit is the main part of the antenna, it can radiate and receive electromagnetic waves, so as to realize wireless communication. The dual-polarized radiating unit can realize space diversity, and can work in the transceiver duplex mode at the same time, greatly reducing the number of antennas and occupying space. The size and height of the radiating unit directly affect the size of the antenna. At present, customers have higher and higher requirements for the miniaturization of the antenna size. However, the existing radiating units generally have large caliber and high height, which leads to the large size of the antenna and cannot satisfy customer's request. Therefore, how to reduce the aperture of the radiation unit is an urgent problem to be...
