摘要： A directional antenna and a communication device are provided. The directional antenna includes an active element and a first reflector. The active element includes a first element and a second element, an operating frequency band of the first element is a first frequency band, and an operating frequency band of the second element is a second frequency band. An equivalent electrical length of the first reflector is equal to or slightly greater than one half of a wavelength of the first frequency band, the first reflector includes a first resonant circuit, the first resonant circuit includes a first capacitive part and a first inductive part that are connected in parallel, a resonance frequency of the first resonant circuit is within the second frequency band, and an equivalent electrical length of a part other than the first resonant circuit in the first reflector is less than one half of a wavelength of the second frequency band. In the directional antenna and the communication device in this application, the first reflector can perform directional reflection on an electromagnetic wave sent by the first element, so as to increase a gain of the directional antenna in a reflection direction.
