Abstract: A compact antenna enabling to produce high gain is based on an antenna main body is constructed in such a way that a plurality of resonance sections, each having parallel-connected respective inductance sections and capacitance sections, are electrically connected in series, and a frequency adjusting capacitance section is connected electrically in series between a ground section at the ground potential and an exit end of the antenna main body. The resonance sections are constructed so that that the characteristic frequency curves overlap one another at least in the width portion to enable the antenna man body as a whole to resonate at substantially one resonance frequency, which is higher than the normal vibration frequency at which each resonance section resonates.

Abstract: An antenna is provided to improve the gain and to eliminate various negative effects caused by a surrounding environment in which the antenna is mounted, such as the effects caused by neighboring metal plates and the like, while providing an antenna structure to facilitate its assembly into various communication devices. The antenna emitting radio waves at a center frequency has an antenna main body and a grounding line section connected to the ground-side of the coaxial cable for supplying power to the antenna main body. The grounding line section starts from a reference point and extends in a loop so as to surround the antenna main body, and portions of the conductor line are severed so as to provide a first end terminal and a second end terminal so that the length of the conductor line from the reference point to the first end terminal corresponds to one quarter of a wavelength of the center frequency or its integral multiple.
