A miniaturized split ring resonator antenna that has good radiation efficiency, wide bandwidth and an omni-directional radiation pattern.

About

Summary: UCLA researchers in the Department of Electrical Engineering have developed a miniaturized split ring resonator antenna that has good radiation efficiency, wide bandwidth and an omni-directional radiation pattern making it ideal for integration on small handset components in wireless communication systems.   Background: Antenna radiation efficiency and bandwidth are directly related to the quality factor of the resonator, which is usually inversely proportional to the antenna size. It is difficult to design a small antenna with high radiation efficiency and wide bandwidth performance, thus most designs do not provide good enough performance for practical applications.   Innovation:   Researchers at UCLA have developed a novel antenna structure based on a vertical split ring resonator configuration that allows for miniaturization while maintaining its small size, good radiation efficiency and high bandwidth performance.   Applications: Bluetooth communication in cell phones and notebook computers  Integration on small handset components for wireless communication systems    Advantages: Miniaturized  Good radiation efficiency  Wide bandwidth  Omni-directional radiation patterns  Small footprint size  Internal matching network
