ABSTRACT:
A cylindrically conformable antenna is formed on a flexible substrate and preferably comprises a complex pattern coupled to a first feedline and, spaced-apart from the complex pattern, a patch that floats electrically. The complex pattern preferably is a fractal pattern, deterministic or otherwise, but need not be a fractal. The shape, size, and position of the patch relative to the complex pattern, as well as the complex pattern itself, produces multiple frequency bands of interest. These bands may be varied by varying the relative parameters associated with the patch and complex pattern. The resultant antenna is substantially smaller than conventional antennas for the same frequency band, has a natural 50 Ω feed impedance and performs substantially as well as larger conventional antennas.
