Abstract
Provided is an antenna unit capable of suitably increasing a 3 dB beamwidth. An antenna unit includes a single feed antenna provided on a dielectric body, and a pair of parasitic antennas provided on one side and another side of the single feed antenna in the dielectric body, and the feed antenna includes a feed line, and a feed body portion including a radiation element supplied with power through the feed line, the pair of parasitic antennas each include a parasitic body portion that has substantially the same shape as the feed body portion, pitches between the feed antenna and the pair of parasitic antennas are substantially equal to each other, and the pitches are each within a range from 0.4λ+{(λ/2)×n} to 0.6λ+{(λ/2)×n} inclusive, where λ denotes a free space wavelength (n is an integer that is 0 or more).
