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.

An electric composite detection antenna is disclosed. The antenna includes two RF antenna disposed on two sides of the circuit system of the electronic device, and a RF compensation system is disposed in the circuit system and includes an inductive sensing coil, and the induction coil can detect signal attenuation of any RF antenna subjected to external interference, so as to generate a detection signal. The RF compensation system can notice the control unit, to quickly drive any antenna matching circuit to switch to the RF antenna which is not interfered, or to quickly adjust antenna power or adjust the matching value of the RF antenna between the external environment, so that the preset electronic device can perform the stable transmission RF signal through the RF antenna without external interference, and maintain better power for RF signal transmissions.

A Wireless Electricity Distribution System (WEDS) and method is provided in the present invention. The apparatus includes a transmitter that transmits a microwave radiation beam towards a receiver. The transmitter includes a source of electricity, an electricity to microwave converter and a reflectarray antenna having a emitter horn and reflect aperture. The receiver includes a rectenna antenna providing a power conditioner. Alternatives include multiple beam transmitters, modular construction, intermediate relay redirectors, and simultaneous data over power transmissions.

The present invention teaches a frequency-scalable high-gain dual-polarization radio beam application platform for private, public, government, or military radio applications such as RFID (radio frequency identification), aerial and robotic inventory scanning, radio communications, telemetry, telecommand, aeronautical radionavigation, radiolocation, earth exploration, space research for terrestrial, air-to-ground, space-to-earth, or space-to-space uses.

The present disclosure generally relates to any device capable of wireless communication, such as a mobile telephone or wearable device, having one or more antennas. By applying a variable reactance (capacitive or inductive component) antenna aperture tuner within a simple, scalar antenna aperture tuning system, the maintenance of a constant antenna resonant frequency in the presence of environmental changes or head/hand effects is obtained. The variable reactance is used to adjust the resonant frequency of the antenna to stay at the desired target frequency in response to external variables that would otherwise shift the resonance away from the operating frequency of the device. Adjusting the resonant frequency of the antenna in response to externally induced changes maintains the radiating efficiency of the antenna and simultaneously avoids impedance mismatch between the antenna and the respective transmit/receive path in the radio, thereby minimizing transmission losses.
