AbstractAn antenna coupler is described which may be used to couple test signal to each antenna channel, in turn, of an AN/UPD-501 antenna system. The radiating element of the coupler is a spiral, and the bandwidth extends from 2 kmc/s to 11 kmc/s. It is designed, in particular, for testing systems which use spiral antennas. The principal feature of the device is that it is nearly reflectionless. Close physical spacing to the antenna under test is possible without the usual errors due to mutual reflections.
