摘要： Disclosed is an antenna using a reactive element that is capable of individually controlling the respective resonance frequencies and resonance bandwidths. The antenna includes a radiator electrically coupled with a feeding point, a first reactive element electrically coupling a first point and a second point of the radiator, and a second reactive element electrically coupling a third point and a fourth point of the radiator. Here, the reactive elements are each coupled to the radiator in parallel, and because of the reactive elements, the antenna is made to have higher-order resonance frequencies that are not integer multiple in relation to a fundamental resonance frequency.
