Abstract :
A novel concept for a frequency channelizer is investigated. A wideband signal is tapped at equidistant intervals along a dispersive line and fed into the array ports of a Rotman lens. The signal is broken into frequency bands, or channels, that are focused at specific beam ports of the lens. This concept was validated experimentally. The frequency band is split into four distinct channels, and the center frequency of each channel agrees well with the predictions.<>
