1. A surface-mount antenna for being connected to a radio-communication high-frequency circuit to operate as an antenna, comprising:

  • a radiation electrode formed on a base member, wherein one end of the radiation electrode serves as a feeding portion for being connected to the radio-communication high-frequency circuit, and the other end of the radiation electrode is an open end, the radiation electrode having a width which increases from the feeding portion toward the open end, a band-like feeding electrode formed on the base member and connected to the feeding portion of the radiation electrode to serve to connect the feeding portion to the radio-communication high frequency circuit, and a ground electrode formed on the base member and disposed on at least one side of the feeding electrode so as to define a spacing with the feeding electrode, and the spacing between the ground electrode and the feeding electrode is smaller than a width of the feeding electrode.
