ABSTRACT:
A collinear series-fed antenna array formed from two spaced-apart electrical conductors extending parallel to one another in a longitudinal direction and having regularly spaced complementary changes in transverse dimensions along the longitudinal direction. These two shaped conductors are connected at one end to an RF transmitter or receiver and are substantially isolated from electromagnetic interaction with other unconnected electrical conductors in the immediate vicinity. The array is preferably fabricated by etching a copper laminate adhered to one side of a dielectric sheet which serves solely to support the shaped conductors etched thereon. There is no ground plane associated with these conductors and the dielectric merely serves to support the antenna elements. The whole assembly can therefore be made very thin and flexible and formed into a compact unit for storage when not in use.
