Abstract
There is disclosed an antenna system comprising: i) first and second antennas, the second antenna being disposed laterally from the first along a longitudinal axis, and ii) an isolation structure disposed between the first and second antennas. The isolation structure comprises a first resonator element having a first arm with upper and lower ends, the first arm connected to ground at its lower end, and a lateral second arm connected to the upper end of the first arm. At least a portion of the first resonator element is disposed adjacent to a portion of the first antenna such that the first resonator element is strongly coupled to the first antenna.
