Abstract

The invention discloses a reconfigurable axe-shaped dual-mode monopole antenna comprising a dielectric plate, a hollow-out metal plate, an axe-shaped monopole structure and an SMA head. The hollow-out metal plate is attached to an upper surface of the dielectric plate, and the axe-shaped monopole structure is attached to a lower surface of the dielectric plate. A step-shaped hollow-out slit is etched on the hollow-out metal plate. An axe-shaped transverse portion of the axe-shaped monopole structure comprises an antiparallelogram metal plate. The SMA head is arranged on the dielectric plate, the axe-shaped monopole structure is electrically connected with a feeding end of the SMA head, the hollow-out metal plate is electrically connected with a ground end of the SMA head. An upper portion of a tip of the antiparallelogram metal plate is provided with a metal pad, the metal pad is in ground connection through a through hole, and the metal pad is connected with the tip of the antiparallelogram metal plate through a lumped capacitance. The two resonant modes of the reconfigurable axe-shaped dual-mode monopole antenna of the present invention can achieve independent tuning, and the resonance mode is reconfigurable.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a reconfigurable ax-shaped dual-mode monopole antenna. Background technique [0002] In order to facilitate the large-scale promotion and application of communication terminals and radio frequency identification systems, the economic cost and size of the terminal or system are crucial considerations. As an important part of the antenna, it must be All require multi-frequency, broadband, and miniaturization. The monopole antenna in the prior art has two resonance modes, one resonance mode is generated by the longitudinal structure of the monopole antenna, and the other resonance mode is generated by the transverse structure of the monopole antenna. At present, the monopole antenna design can effectively adjust the frequency bandwidth of the antenna by adjusting its horizontal and vertical dimensions reasonably. However, it is basically difficult for the current monopole an...
