This approach is used to develop large Yagi-Uda antennas operating at 500 MHz, with antenna elements carried by multiple small UAVs. The system’s reconfigurability allows multiple flying UAVs to dock ...
This reflectarray uses an electronically reconfigurable unit cell, consisting of an antenna and a reflecting circuit that provides 2-bit reflection phase shift. A general method for designing this ...
The antennas scatter light in proportion to the electrical signals they detect, allowing researchers to capture real-time cellular interactions with remarkable accuracy.
