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.

10. An antenna, comprising:
-
a main element configured to transmit and receive a signal; and at least one director-reflector unit coupled to the main element and comprising; a first radiation element; a second radiation element, a total electrical length of the first radiation element and the second radiation element being greater than one half of a wavelength corresponding to an operating frequency band of the antenna, and both an electrical length of the first radiation element and an electrical length of the second radiation element being less than the one half of the wavelength corresponding to the operating frequency band of the antenna; and a switch, one end of the first radiation element being coupled to one end of the second radiation element using the switch and the at least one director-reflector unit being 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 first radiation element being decoupled from the second radiation element and the at least one director-reflector unit being used as a director and configured to direct the signal transmitted and received by the main element when the switch is switched off. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
