An antenna device includes a dielectric substrate having a first surface on which an antenna part is formed and a second surface on which a base plate is formed. The antenna part has one or more antenna patterns configured to act as radiating elements. The antenna patterns resonate in one or more resonance directions to incident waves having an operating frequency of the antenna part, thereby generating emitted waves having polarized waves different from those of transmitted/received waves which are transmitted/received by the antenna part. For each of the resonance directions, the antenna patterns include at least one line pattern having a width which is narrower than the total width of the antenna patterns in a direction perpendicular to the resonance direction.

An electronic device may include first and second antennas formed from respective first and second segments of a housing. The first antenna may have a first feed coupled to the first segment by a first switch and coupled to the first segment by a first conductive trace. The second antenna may have a second feed coupled to the second segment by a second switch and coupled to the second segment by a second conductive trace. The first segment may be separated from the second segment by a single gap, a data connector may pass through the second segment, and the antennas may selectively cover a low band. Alternatively, the first segment may be separated from the second segment by a third segment and two gaps, the data connector may pass through the third segment, and the first and second antennas may concurrently cover the low band.
