A broadband blade monopole antenna is disclosed. The broadband blade monopole antenna includes a body portion that is substantially flat to define a two-dimensional plane that the body portion extends along. The body portion defines an outer perimeter having four sides. The four sides are grouped into two pairs of equal-length sides positioned directly adjacent to each other. The broadband blade monopole antenna provides at least about 100% impedance bandwidth.

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.
