Abstract: An antenna includes a director-reflector unit, which includes two radiation elements, and a switch, and a main element configured to transmit and receive a signal. Total electrical length of the two radiation elements is greater than one half of a wavelength corresponding to an operating frequency band of the antenna, and electrical length of either of the two radiation elements is less than one half of the wavelength corresponding to the operating frequency band of the antenna. The two radiation elements are coupled using the switch and the director-reflector unit is used as a reflector and configured to reflect the signal transmitted and received by the main element when the switch is switched on, and the two radiation elements are decoupled and the director-reflector unit is used as a director and configured to direct the signal transmitted and received by the main element when the switch is switched off.
