An antenna for enhancing characteristic of a beam with reducing PIMD is disclosed. The antenna includes a reflection plate, at least one first choke member disposed on one side of the reflection plate, an insulated member disposed between the reflection plate and the first choke member, thereby separating the first choke member from the reflection plate, wherein the insulated member is an insulator, and a connection member configured to connect electrically the first choke member to the reflection plate through the insulated member, wherein the connection member is a conductor.
Description
technical field Exemplary embodiments of the present invention relate to an antenna having a choke member, and more particularly, to a PIMD-reduced antenna connecting a choke member to a reflection plate. Background technique The antenna transmits / receives electromagnetic waves by radiating a radiation pattern, and generally has the following structure shown in FIG. 1 . FIG. 1 is a perspective view showing a general antenna. In FIG. 1 , the antenna includes a reflector 100 and a radiation device 102 . The reflection plate 100 has a shape bent in a certain direction as shown in FIG. 1 , and includes a base member 100A and a bending member 100B. The radiation devices 102 are sequentially arranged on the reflection plate 100 . The antenna outputs a beam in a given direction using a radiation pattern radiated from the radiation device 102 . A phase shifter (not shown) is formed on a second surface opposite to the first surface of the reflection plate 100 on which the r...
