Abstract

A wireless device includes a ground plane layer having a maximum size smaller than half of a longest free-space operating wavelength of the wireless device, a boosting element having a largest dimension smaller than ⅙ times the longest free-space operating wavelength, and a radiofrequency system with a tunable reactive circuit. The tunable reactive circuit includes a switch connected between the boosting element and a transceiver and a bank of fixed matching networks. At least a portion of an orthogonal projection of the boosting element onto a plane containing the ground plane layer overlaps the ground plane layer.
