摘要： Disclosed is an antenna desensitization system and a method for designing an antenna desensitization system. The system and method are operative to provide a configuration and positioning of an antenna desensitizer element, with respect to an antenna, to overcome a frequency detuning experienced during operation of such antenna. The antenna desensitizer element comprises one or a combination of more than one decoupling components selected from the group of a frequency selective surface, an electromagnetic band gap structure, a ferromagnetic material, an anisotropic material, a nanomaterial, a dielectric material, and a conductive material. The system and method are particularly suitable for reducing the antenna frequency detuning effects caused by an external agent, such as a user or operator of a mobile electronics device, during operation of such device.
