Why a DF Antenna Array?
Successful direction-finding requires a DF antenna array. In the past, DF antenna arrays have been the limiting factor in DF systems. With high performance DF antenna arrays, covering an ultrawideband frequency range and able to transmit and receive ultrawideband (impulse-type) signals, high gain, accurate direction-finding is enabled. DF antenna arrays are composed of multiple antenna elements in a single enclosure (radome). To cover all azimuth angles at all times, one should use a circular DF antenna array. The elements point in different directions, to pinpoint the direction of signal origin most effectively. DF antenna arrays can be used for transmit and receive throughout an ultrawideband frequency range. Custom DF Antenna Arrays The development of a custom DF antenna array typically can be based on minimal information from the end user: The volume (cylinder diameter and height) available for the array, the maximum acceptable weight, number of elements (ports), whether an omnidir
