Abstract
A holographic antenna includes a transmission line and a plurality of interdigital capacitor (IDC) slots respectively formed along the transmission line. The holographic antenna also includes an active tuning device connected to each IDC slot from the plurality of IDC slots. Each active tuning device is configured to provide a holographic pattern on the plurality of IDC slots in response to the holographic antenna transmitting or receiving an electromagnetic signal. The holographic pattern is controllable for scanning an electromagnetic beam by the holographic antenna. The holographic antenna also includes a biasing source coupled to each active tuning device and configured to control its respective operation.
