The radiation structure of the second low-frequency dipole arm 43 and the second high-frequency dipole arm 42 connected by the dipole arm 41 is convenient to adjust the impedance of the antenna to increase and can adjust the impedance of the dual-frequency antenna to increase the first dipole part 2 and The bandwidth of the radiation frequency band of the second dipole part 4 makes the performance of the antenna more stable.
In some specific embodiments, at least one of the two opposite sides of the substrate 1 is provided with a reflector 6, that is, no matter which side of the substrate 1 is provided with a vibrator group, it can be placed on the substrate according to actual needs. 1 is provided with a reflector 6 to improve the omnidirectional effect of the antenna.
[0038] It can be understood that the connector 3 can transmit the electricity of the feeding device or the feeding network to the multiple first vibrator parts 2 of the vibrator group, so that the multiple first vibrator parts 2 can work together as a radiation structure, To enhance the radiation performance of the antenna. When feeding power, the antenna can generate resonance in the high-radiation frequency band and low-radiation frequency band, so that the antenna can simultaneously realize the functions of high-frequency strong orientation and low-frequency weak orientation. Specifically, when the first high-frequency dipole arms 22 and the first connecting dipole arms 21 of the multiple first dipole parts 2 are both working, and the first low-frequency dipole arms 23 are all stopped working, the vibrator group can real...
