Abstract
The CBR (cavity-backed radiator) panel element has been proven to have high versatility and predictability in multiplexed FM antenna array radiation patterns. Special customized patterns with deep nulls (notch patterns) are discussed. The desired patterns can be accomplished by skewing the corresponding CBR elements off center by an appropriate amount and by adjusting the electrical phase of the corresponding feedline in order to obtain the necessary phase difference between the adjacent cavities
