1. A surface mount antenna comprising:

  • a substrate; and

    a radiation electrode disposed on the substrate and arranged to perform an antenna function;

    wherein the radiation electrode is disposed on four continuously connected surfaces of the substrate including a top surface, a bottom surface, and two shorter edge surfaces of the substrate, thereby defining a configuration in which the radiation electrode essentially surrounds an outer circumference of the substrate;

    a slit is formed in the radiation electrode in a direction intersecting an outer circumferential direction of the substrate and extends across the whole width of the radiation electrode; and

    at least one of two electrode ends located close to each other with the slit interposed therebetween is cut for adjusting the resonance frequency of the radiation electrode.
