Abstract

The embodiment of the invention discloses a dipole antenna array, comprising a driving dipole and at least two parasitic dipoles arranged on the same substrate; Wherein the parasitic dipole is arranged on both sides of the driving dipole or on the same side of the driving dipole, the length of each parasitic dipole is the same, and the length extension direction of the driving dipole is parallel to the length extension direction of each parasitic dipole. Compared with the prior art, the embodiment of the invention can realize steep filtering frequency response and has wide impedance bandwidthby introducing an equal-length parasitic dipole to both sides or either side of the driving dipole.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a dipole antenna array. Background technique [0002] In recent years, the rapid development of wireless communication systems has stimulated novel antenna technologies with multifunctional properties. Since, in some cases, external signals can be unusually strong compared to in-band signals, wireless communication systems require antennas with a certain degree of anti-jamming capability. [0003] Among them, the dipole antenna is widely used because of its simple structure, low cost and high efficiency. At present, there are many research works on the use of parasitic elements to improve the performance of dipole antennas, such as increasing the gain or expanding the impedance bandwidth. However, this type of dipole antenna will inevitably change the far-field radiation characteristics of the antenna, and it is difficult to achieve a steep Filtered frequency response, so...
