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.
An antenna comprised by an antenna main body having a plurality of resonance sections connected electrically in series, wherein each resonance section has an inductance section and a capacitance section connected electrically in parallel and resonates at an normal vibration frequency;
A method for making an antenna comprising:
