Abstract: A sum and difference mode antenna includes a first radiator, a second radiator, a first excitation source, and a second excitation source. The first radiator includes a first segment, a second segment, and a gap formed between the first segment and the second segment, and the first excitation source is configured to feed the first radiator, so that currents in the first segment and the second segment both flow in a first direction. The second radiator includes a third segment, a fourth segment, and a fifth segment. The third segment and the fourth segment are symmetrically distributed on two sides of a connection end of the fifth segment, and the second excitation source is electrically connected to a feed end of the fifth segment to feed the second radiator.
