Abstract:
Disclosed are a dual-band antenna and an unmanned aerial vehicle. The dual-band antenna comprises a substrate, a coaxial line, a grounding member, a first radiator, a second radiator, and a sleeve radiator. The substrate comprises a first surface. The coaxial line comprises an inner conductor and an outer conductor insulated from the inner conductor. The grounding member is disposed on the first surface and is electrically connected to the outer conductor. The first radiator is disposed on the first surface and is electrically connected to the inner conductor. The first radiator is spaced apart from the grounding member. The second radiator is disposed on the first surface and is electrically connected to the grounding member. The first radiator is spaced apart from the second radiator to couple and feed the second radiator. The sleeve radiator is sleeved outside the coaxial line and one end of the sleeve radiator is electrically connected to the outer conductor. The dual-band antenna disclosed in the present invention can cover two antenna bands of 900 MHz and 2.45 GHz simultaneously, has good omnidirectional radiation performance in the two bands of 900 MHz and 2.45 GHz, and can effectively simplify the structure of the antenna and reduce the size of the antenna.
