1. An antenna, comprising:
an antenna body that includes a plurality of first antenna elements, which are disposed along a first straight line; a hollow conductor, disposed in the antenna body, which conductor extends between the first antenna elements; wherein the first antenna elements are implemented as openings extending between the hollow conductor and a surface of the antenna body, wherein the antenna is configured to radiate a signal in one spatial direction, the spatial direction being a function of a frequency of the signal, and wherein the antenna body has an electrically insulating material, which is coated with a conductive material; and a plurality of antenna columns, wherein each antenna column includes a plurality of fifth antenna elements, wherein each antenna column is oriented perpendicularly to the first straight line, wherein in each antenna column, all the fifth antenna elements of the antenna column are coupled to a respective one of the first antenna elements via a coupling structure, and wherein each antenna column is configured as a microstrip antenna, and wherein the fifth antenna elements are configured as patch elements. |
