A Compact Dual-band Antenna Using Triangular Split Ring Resonator for Bluetooth/WiMax/LTE Applications

A compact dual-band microstrip-fed planar antenna is proposed for Bluetooth (2.4 GHz), WiMax (2500MHz/3650MHz) and LTE (2570MHz-2620MHz/3600MHz-3800MHz) applications. A triangular ring resonator with a split at asymmetry position is used to realize dual-band response. The antenna provides two resonances at 2.6 GHz and 3.7 GHz. The structure is simulated and studied for S-parameters, radiation patterns and gain values, and the results are presented and discussed throughout the paper. The structure is fabricated and results are compared with simulated results to validate the simulation. The simple design of this proposed antenna and its miniaturized dimension reveals significance of this design.
