US 11,114,765 B2 · Dipole antenna structure

Abstract

The present invention provides a dipole antenna structure including a planar antenna element and a reflection plate which is directly under the planar antenna element. The planar antenna element includes a main radiator and secondary radiators. The main radiator is a rectangular metal sheet in which a rectangular opening and two convex portions are provided. A gap is provided between the two convex portions which bisect the rectangular opening into two rectangular portions of equal size, and the gap connects the two rectangular portions. The secondary radiators are arranged on the short sides of the planar antenna element. The antenna is simple in structure, convenient to produce and install, high in signal reception quality, wide in signal coverage, and can enhance signal reception in the UHF band to improve stability of the signal reception.
