A system for communicating data over a transmission line is disclosed. In one example implementation, the system may include a transmitter configured to modulate a control signal onto an RF signal using amplitude-shift keying modulation to generate a transmit signal. The system may include a receiver and a transmission line coupling the transmitter to the receiver. The transmitter may be configured to transmit the transmit signal over the transmission line to the receiver, and the receiver may be configured to de-modulate the control signal and extract clock information associated with the transmitter. In some embodiments, the system may include a tuning circuit and a modal antenna, and the tuning circuit may be or include the receiver. The receiver may be configured to adjust a mode of the modal antenna based on the control signal transmitted by the transmitter.

Systems and methods are provided for enabling a notch-based element that retains traditional notch ultra wideband (UWB) performance while having a highly-producible/-scalable structure, high power handling, a simple single-ended 50 ohm feeding, and relative insensitivity to a conductive back-plate. Embodiments of the present disclosure improve upon the traditional notch structure to further offer shorter element depth, lighter weight, and modularized assembly.

An antenna element comprises one or more directors, a resonator, and a three dimensional ground assembly. Parts of the antenna element are arranged on three metal layers. A top layer has an unconnected metal bar which forms a beam director, a resonator and a top part of the ground assembly. The resonator is an integral piece substantially in the form of a loop connected to a feed line and a feed line terminal ending. The feed line terminal ending serves as the ground plane for the feed line as well as providing impedance matching from the external transceiver circuit to the resonator. The ground assembly includes a top layer ground connected to a plurality of metallized half cylindrical hole channels (or metallized via holes) which connect to a ground terminal in a bottom layer.
