Abstract

The invention provides a dual-band wideband electronic small antenna. The electronic small antenna comprises a pyramid structure, an earthing metal column, a circular floor structure and a coaxial feeder, wherein the pyramid structure comprises a pyramid part, a pyramid tail-end horizontal unfolding part and an arc-shaped roof; the pyramid tail-end horizontal unfolding part is formed at the tail end of the pyramid part; the arc-shaped roof is loaded on one side, opposite to the pyramid part, of the pyramid tail-end horizontal unfolding part; the pyramid structure is connected with one end of the earthing metal column through the pyramid tail-end horizontal unfolding part; the earthing metal column is positioned on the same side as the pyramid part of the pyramid tail-end horizontal unfolding part; the other end of the earthing metal column is connected with the circular floor structure; the earthing metal column is provided with a truncation crack; a lumped circuit is loaded in the truncation crack, and comprises a resistor and an inductor which are in series connection with each other; a first through hole is formed in the center of the circular floor structure; the coaxial feeder penetrates through the first through hole, and is in contact with the top end of the pyramid part for feeding. The electronic small antenna is suitable for popularization and application in the field of antennas.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-frequency broadband electrically small antenna. Background technique [0002] The antenna size of a wireless communication device is generally related to the wavelength corresponding to its working frequency band. If a monopole-type antenna is used, at least 1 / 4 of the antenna length of the wavelength is required to generate resonance, so the size of the monopole-type antenna is usually large. In practice, multiple antennas are usually placed at the same time, and when the space for installing the antennas is limited, the electromagnetic interference between the monopole antennas will affect the communication quality. [0003] In the prior art, miniaturized antennas can overcome the above defects, such as electrically small antennas. When the electrical dimension T of the antenna is less than 1, it can be called an electrically small antenna, and the electrically small a...
