Abstract
A communication apparatus and method, an antenna apparatus, and a communication system that prevent reduced communication characteristics are disclosed. In one example, a coupled antenna element positioned in the vicinity of a communication apparatus is detected, adaptation of impedance is controlled on the basis of the detection result, and wireless communication is performed via the coupled antenna element with the adapted impedance. In addition, an antenna element is excited by a wireless signal from a communication apparatus positioned in the vicinity of the antenna element, and this communication apparatus is notified of being positioned in the vicinity of this antenna element.
