Embodiment Construction

[0033] In order to make the objects, technical solutions and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are intended to explain the present invention and is not intended to limit the invention.

[0034] See figure 1 The first embodiment of the present invention provides an antenna unit 100 comprising a ground layer 10, a second dielectric plate 20, a second polarization assembly 30, a first dielectric plate 40, and a first polarization assembly 50. The first polarization assembly 50 and the second polarization assembly 30 are stacked over the ground layer 10. The first polarization assembly 50 and the second polarization assembly 30 are used to generate orthogonal polarization. The first dielectric plate 10 and the second dielectric plate 20 are superposed, and the second dielectric plate 20 is dis...

Abstract

The present invention provides an antenna unit and an array antenna, wherein the antenna unit includes a ground layer and a first polarized component and a second polarized component stacked on the ground layer; the first polarized component includes a first radiating part, a first feeding line disposed on a side of the first radiating part close to the ground layer, and a first coaxial line sandwiched between the first feeding line and the ground layer; the The first radiating part includes a first pole and a second pole arranged at intervals along the first direction; the second polarization component includes a second radiating part, which is arranged on a side of the second radiating part away from the ground layer The second feeder line and the second coaxial line interposed between the second radiating part and the ground layer; the second radiating part includes third poles and fourth poles arranged at intervals along the second direction Pole, the first polarizing component and the second polarizing component are used to generate orthogonal polarization. The array antenna includes the aforementioned antenna unit.

Description

[Technical field] [0001] The present invention relates to the field of communication technology, and more particularly to an antenna unit and an array antenna. 【Background technique】 [0002] Currently in millimeter bands, there is less research on two-frequency and bipolar. 28GHz and 39GHz have a narrow bandwidth of 28GHz, and the form is too complex, and the cross-polarization of bipolarization is still poor, and there is a certain disadvantage in volume. [Summary] [0003] The present invention provides an antenna unit and an array antenna to solve the presence of existing dual-band and bipolarization antennas. [0004] In order to achieve the above object, the present invention provides an antenna unit including a ground layer and a first polarization component and a second polarization assembly over the ground floor; the first polarization The assembly includes a first radiation portion disposed at the first feed line near the ground plane and a first coaxial line between t...
