Abstract

The invention discloses an axe-shaped dual mode monopole antenna. The axe-shaped dual mode monopole antenna comprises a medium board, a hollow-out metal plate, an axe-shaped monopole structure and an SMA head, wherein the hollow-out metal plate fits an upper surface of the medium board, the axe-shaped monopole structure fits a lower surface of the medium substrate, a step-shaped hollow-out slit is formed on the hollow-out metal plate through etching, the axe-shaped monopole structure comprises a bar-shaped vertical portion and an axe-shaped transverse portion, the bar-shaped vertical portion of the axe-shaped monopole structure is perpendicular to long edges of the lower surface of the medium board, the axe-shaped transverse portion of the axe-shaped monopole structure comprises antiparallelogram metal plates symmetrically arranged at two sides of the bar-shaped vertical portion of the axe-shaped monopole structure, the SMA head is arranged on the medium board, the axe-shaped monopole structure is electrically connected with a feed end of the SMA head, and the hollow-out metal plate is electrically connected with a ground end of the SMA head. The axe-shaped dual mode monopole antenna is advantaged in that independent tuning of two resonance modes can be realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an 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 antenna to effe...
