Surface-mount antenna and communication apparatus using the same

摘要

A surface-mount antenna includes a dielectric substrate having a rectangular parallelepiped shape and a radiation electrode having a meandering pattern disposed on the surface of the dielectric substrate. The radiation electrode includes at least two meandering electrode units formed with different meander pitches, the at least two meandering electrode units being connected in series, and the radiation electrode being formed over at least two faces among a front face, a major surface, and a end surface of the dielectric substrate. With the above-described construction, the radiation electrode is allowed to transmit and receive electromagnetic waves in at least two different frequency bands.
