An antenna includes: a radiation patch; a feed line having a first stage through which power is fed to the radiation patch, and a second stage connected to a feed terminal; a transformer disposed between the radiation patch and the first stage of the feed line and configured to match an impedance of the radiation patch with an impedance of the feed line; and a filter connected in series between the first stage and the second stage of the feed line and configured to filter resonances generated at frequency bands corresponding to integer multiples of a frequency applied to the radiation patch.
