Based on clues taken from the design of antenna arrays, multibranching techniques are used to expand the frequency performance of slotted waveguide power amplifiers. Both simulated and measured results reveal that the use of a corporate feed network may improve the bandwidth of the linear slotted amplifier by up to 50%. © 2002 John Wiley & Sons, Inc.
