Abstract
An apparatus comprises an antenna ground plane; a conductive side element, a first antenna resonating element; a second antenna resonating element; and a slot-based antenna element formed from slot structures between the conductive side element and the conductive housing element. At least two RF switches are loaded with lump loads, located across the slot-based antenna element and dividing the slot-based antenna element to sections. A first antenna resonating element capacitively coupled to the slot-based antenna element, and forming a first antenna operating at a first frequency; the second antenna resonating element capacitively coupled to the slot-based antenna element, and forming a second antenna operating at a second frequency; and wherein the first and the second frequency are configured to be tuned at different frequencies based on a lump load switched by the first and the second RF switches.
