Abstract:
1. An antenna comprising: a ground plane; a feed point; a ground point; and an antenna track extending between the feed point and the ground point and comprising, in series connection, a first loop and a second loop and having a first continuous band of operation and a second continuous band of operation, wherein the first continuous band of operation corresponds to a fundamental resonant frequency of the antenna, and the second continuous band of operation corresponds to the second and third harmonic resonances of the fundamental resonant frequency of the antenna, wherein the third harmonic is tuned, using reactive loading, towards the second harmonic; and wherein the antenna track has a length L, and the reactive loading comprises a first inductive load located at a position between L/5 and 2L/5 from the ground point and a second inductive load located at a position between 3L/5 and 4L/5 from the ground point.
