Unstoppable Wireless Wave!
R&D on MW/MMW circuits for future wireless applications

Welcome to Advanced Microwave Labs, Saitama University. We carry out theoretical/numerical research and experimental investigations in the area of microwave/millimeter-wave circuit design and development.
Our research is headed by Prof. Z. Ma and Dr. M. Ohira, Saitama University, Japan.

• Design and development of compact high-performance microwave and millimeter-wave filters.
• Novel compact ultra-wideband bandpass filters for UWB communications
• Millimeter-wave wideband bandpass filters for mmw communications
• High-performance compact bandpass filters for next-generation wireless communications
• Microwave/millimter-wave filtering antennas
• Power dividers
