Abstract: Multi-band antenna for use with limited size ground planes. In one embodiment, the multi-band antenna includes a substrate having a first radiator branch and a second radiator branch; a first switch that is connected with the first radiator branch and a radio module; and a second switch that is connected with the second radiator branch and matching circuitry. Selection between different states of the first switch and the second switch enable the multi-band antenna to operate in a plurality of operating bands. These operating bands may include both the high and low frequency bands for a long-term evolution (LTE) communication device as well as a global navigation satellite system (GNSS) frequency band. Methods of operating the multi-band antenna as well as systems that incorporate the multi-band antenna are also disclosed.

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.
