摘要：An antenna structure includes a radiation conductor made of a metal plate thatis supported by legs provided upright on a surface of a dielectric substrate and is spaced

apart from the surface. The radiation conductor is circularly shaped such that the contourof the radiation conductor conforms to the outer periphery of the dielectric substrateand such that the radiation conductor includes an open portion. One of the legs functionsas a feeding terminal and the other functions as a grounding terminal, whereby theradiation conductor operates as a dipole antenna. The radiation conductor has slots foradjusting impedance. Impedance can be adjusted by changing the length of the slots.
