Problems solved by technology

[0015] Therefore, there is a problem that the major axis 300 of the +45° polarization produced by the dipole assemblies 100, 102, 104, 106 is shifted to the right of the +45° axis 302, as shown in FIG.
As a result, it is difficult to radiate the main beam in the desired direction
In particular, such shifting phenomenon of the radiation pattern in the low frequency band is more severe than that of the radiation pattern in the high frequency band

Abstract

An antenna for compensating a phase of a current passing to a dipole member so as to prevent a shift phenomenon of a radiation pattern is disclosed. The antenna includes dipole members, and a feeding section connected to the dipole members, and configured to have at least two feeding points for providing current inputted from an outside device to the dipole members. Here, a first feeding point of the feeding points is connected to a second feeding point of the feeding points, the current is provided to the second feeding point through the first feeding point, and at least one of a slit and a projection member is formed to one or more of the dipole members.

Description

technical field [0001] Exemplary embodiments of the present invention relate to an antenna, and more particularly, to an antenna that compensates a phase of a current flowing through a dipole member to prevent a shift phenomenon of a radiation pattern. antenna. Background technique [0002] An antenna transmits or receives electromagnetic waves by radiating a radiation pattern, and generally has the following structure shown in FIG. 1 . [0003] Fig. 1 is a plan view of a common antenna. [0004] 1, the antenna produces dual polarization (dual polarization), and includes a first dipole assembly 100, a second dipole assembly 102, a third dipole assembly 104, a fourth dipole assembly 106, and a feeding section (feedingsection) 108. [0005] The feed section 108 has a first feed point 130A, a second feed point 130B, a third feed point 130C, a fourth feed point 130D, a first connection line 132A, and a second connection line 132B. [0006] The first feeding point 130A is con...
