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
