Title: Multi-Band Mode-Composite Antennas for Millimeter-Wave and Sub-6-GHz Applications

In order to save the overall volume of the wireless communication systems operating in both millimeter-wave and sub-6-GHz bands, multi-band antennas with a large frequency ratio have attracted increasing attention in recent years. The mode-composite structures that support resonant modes at both millimeter-wave and microwave frequencies are employed to construct the compact multi-band antennas for millimeter-wave and sub-6-GHz applications in this talk. Both the operating mechanism and the design considerations will be analyzed. The measured and simulated results will be discussed as well. With the promising multi-band characteristics and the simple configurations, the presented antennas would be valuable to the design of future portable wireless communication devices.
