Abstract
The present invention provides a metrology antenna system that combines a sleeve dipole antenna having two coaxial input ports with a balancing network. This combination (1) minimizes or eliminates spurious radiation from the balancing network (2) provides for a symmetric pair of feed regions which may be made arbitrarily small, and (3) provides for an essentially perfect impedance match to a broad range of resistive source impedances. The present invention provides a fabrication of arbitrarily small feed regions such that dipoles can be realized at high frequencies at little manufacturing cost.
