Radio Antenna With Improved Feed System

Tech ID: 17507 / UC Case 2005-071-0


Log-periodic antennas are capable of transmitting and receiving signals across a large bandwidth. However, their bandwidth range can be too large for the entire signal to be simultaneously digitized.

To address this issue, researchers at UC Berkeley have developed an innovative feed for broadband antennas. This feed converts the broadband radio signals such that they can be more readily digitized and processed.
