Surface-mount antenna and communication device with surface-mount antenna

摘要

A first radiating electrode 5 and second radiating electrode 6 are formed on an upper face 2c of a dielectric base 2 of a surface-mounted antenna 1, and a rectifying circuit 7 is formed on a side face 2b where radiating electrodes 5 and 6 are not formed. This facilitates configuration of a desired rectifying circuit 7 appropriate for the surface-mounted antenna 1, and rectification of the surface-mounted antenna 1 is facilitated. Also, since the rectifying circuit 7 is formed on the side face 2b of the dielectric base 2, effects of the rectifying circuit 7 on the first radiating electrode 5 and second radiating electrode 6 on the upper face 2c can be reduced. Accordingly, high gain and increased bandwidth of the surface-mounted antenna can be obtained.
