Compact and triple band meta-material antenna for all WiMAX applications

In this paper we propose a compact triple band metamaterial antenna in CPW configuration to cover all the operating frequencies of WiMAX (2.1-2.6 GHz band, 3.3-3.7 GHz band, and 5.2-5.9 GHz band) in one device. The overall antenna dimensions are only 4 cm X 3 cm approximately. Compared with the conventional antenna, the reported antenna presents at least 66% size reduction at lower band. The reported antenna was designed using a monopole antenna loaded by two LH unit cells formed by inductive slots and interdigital capacitors. The antenna performance using the electromagnetic full wave simulations confirmed by experimental results are introduced at the whole designed frequencies.
