Gain-Enhanced Antenna with Metamaterial Structure and Pin Array Reflector for WiMAX and WLAN Applications

摘要

An antenna for WiMAX at 3.7 GHz and WLAN at 5.8 GHz consists of an asymmetric triangular metamaterial structure fed by coplanar waveguide (CPW). The characteristics of the structure are studied using parametric retrieval and eigenmode analysis. Measured performance is in good agreement with simulation. Owing to its single layer 50 Omega CPW design, this antenna is easily integrated with other RF circuits.
