The lab researches antennas and microwave circuits that freely manipulate electromagnetic waves.

AboutAbout the lab
A lab for antennas that freely control electromagnetic waves
The Sano Lab studies antennas and microwave circuits for use in a variety of wireless systems.
It works on improving the performance and adding functions to planar antennas.
It also focuses on metasurface technology, which freely controls the reflection, transmission, and polarization of electromagnetic waves.
It is a new lab that was established in April 2025.
Key terms
- Reflectarray antenna
- A thin, lightweight, low-cost antenna that serves as an alternative to conventional parabolic antennas. Its elements change the phase of electromagnetic waves.
- Metasurface
- Technology that freely controls the reflection, transmission, polarization, and other properties of electromagnetic waves.
- Phased array antenna
- An antenna made up of many circuit elements. It is contrasted with the low-cost configuration of the reflectarray antenna.

The Sano Lab studies antennas and microwave circuits for use in a variety of wireless systems. It focuses on improving the performance and adding functions to planar antennas, on metasurface technology that freely manipulates electromagnetic waves, and on microwave circuits that bring out the best performance of antennas.
*Illustrative imageHigher-Performance Reflectarray Antennas
This research aims to improve the performance of reflectarray antennas that can be manufactured on printed circuit boards. Elements printed on the board change the phase of electromagnetic waves, strengthening radiation in the target direction while preventing radiation in unwanted directions.
*Illustrative imageAntennas That Change Beam Direction
The lab studies reflectarray antennas whose beam direction can be changed freely. Simple mechanical scanning can point the beam in any direction, and this can be realized with a lower-cost configuration than phased array antennas, which require many circuit elements.
