Flexible Hilbert-Curve Loop Antenna Having a Triple-Band and Omnidirectional Pattern for WLANWiMAX Applications

Abstract EN

A triple-band flexible loop antenna is proposed for WLAN/WiMAX applications in this paper.

The proposed antenna is formed by the third-order Hilbert-curve and bending type structure which provides flexible characteristics.

Even though the radius of the curvature for bending antennas is changed, a triple-band feature still remains in the proposed antenna.

Moreover, the antenna exhibits the characteristics of omnidirectional radiation pattern and circular polarization.

To verify the receiving performance of antenna, a simulation on the antenna factor was conducted by an EM simulator.

Based on these results, the suggested antenna makes a noteworthy performance over typical loop antennas.
