Abstract

The invention discloses a planar folded dipole antenna. The planar folded dipole antenna is of three-layer structure. The first layer is a substrate, the second layer comprises a radiation unit, a first metal line, a second metal line, a first signal feed-in portion, a second signal feed-in portion, a first loading unit, a second loading unit, a third loading unit, a fourth loading unit, a fifth loading unit, a sixth loading unit, a seventh loading unit and an eighth loading unit, and the third layer is an insulation layer. The radiation unit is arranged in the middle of the surface of the substrate in a rectangular or approximately rectangular manner, and the width of each side is 1 / 40 of the resonant wavelength.

Description

technical field [0001] The invention relates to the technical field of planar antennas, in particular to a planar folded dipole antenna. Background technique [0002] The folded vibrator is one of the commonly used wire antennas. Its most common structure is a narrow rectangular ring, where the length of the wide side is much smaller than the length of the long side, and the feed is at the center of the long side, and the length of the long side is taken as half of the wavelength , The characteristic impedance is about 300Ω. When the folded vibrator is made of a wire antenna into a planar antenna, it cannot be simply modified, and the problem that the impedance characteristic cannot be maintained in a wide frequency band must be solved. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a planar folded dipole antenna capable of maintaining impedance characteristics in a wide frequency band. [0004] In order ...
