Microwave Communication Devices Laboratory

Exploring new possibilities for wireless technology

Wireless technology has taken a leap forward since wireless telegraphy was first made available more than 100 years ago. Now wireless devices such as mobile phones, Global Positioning System (GPS) and WiFi are indispensable commodities in our daily lives. In the 20th century, putting information on radio waves has completely changed the human society. It is said that putting electricity on radio waves will open new horizons in the 21st century. Our laboratory is studying high-frequency circuit technologies in order to realize wireless power transmission, in addition to wireless information communication. Let’s make new technologies together while dreaming of a future society where batteryless smart watches will operate by receiving electricity from nearby TV radio waves.
