Null-forming synthesis for cylindrical patch arrays

A synthesis method is modified to synthesize patterns with multiple nulls in an otherwise omnidirectional pattern for cylindrical microstrip patch arrays. The directive radiation pattern of a cylindrical microstrip patch is incorporated into the synthesis procedure. The effect of the number of array elements and interelement spacing is investigated. © 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 32: 442–446, 2002.
