Hybrid termination of metamaterial CRLH antennas

This paper introduces a new hybrid termination of composite right left handed antenna. The hybrid termination if formed by short circuit loading coupled to open loading through air gap capacitor. A novel antenna operates at 2.4 GHz and 5.2 GHz with antenna dimensions 21×30 mm² (only 9% compared to conventional microstrip antenna). The proposed new termination has resulted in increasing the electrical length of the open circuit composite right left handed antenna by 20%. for the same physical dimensions. The proposed antenna theoretical concepts is explained. The antenna performance is validated by full wave simulation and experimental measurements.
