Abstract: In this work, a C-band passive microstrip four-element antenna-array beam-forming netw'ork (BFN) using high-directivity directional couplers is described. In the transmit mode, an input signal is split into four equipliase equiamplitude parts so as to correctly feed the elements of a linear/2-D array. The amplitude difference among the four feeds is within 0.5 dB, and the phases of the signals at the feeds differ by less than 10° in a 4:1 bandwidth. ©1999 John Wiley & Sons, Inc.
