Active composite right/left-handed leaky-wave antennas

A high-gain active CRLH LWA has been presented. Different modifications in the layout of the microstrip CRLH LW structure most commonly used up to now have been proposed. A remarkable reduction in the cross-polar component, increasing the XPD in more than 28 dB, and a beam forming from fan-beam to p...

Summary:A high-gain active CRLH LWA has been presented. Different modifications in the layout of the microstrip CRLH LW structure most commonly used up to now have been proposed. A remarkable reduction in the cross-polar component, increasing the XPD in more than 28 dB, and a beam forming from fan-beam to pencil-beam radiation pattern have been demonstrated. By means of the proper amplifier choice, the proposed maximum directivity design of the 2D active CRLH LWA can also be extended to different current distributions and may therefore be used for static or dynamic beam forming
