Method for direct connection of MMIC amplifiers to balanced antenna aperture

摘要

A MMIC amplifier is directly connected to the balanced feed points at the aperture of an antenna to eliminate the distance between electronics coupled to the antenna and the antenna itself, such that interfaces, components and connection lines which introduce losses and parasitic effects that degrade system performance are eliminated due the direct connection. Expanding the aperture of the antenna to accommodate the direct connection of a MMIC amplifier to balanced feed points of an antenna has been found to have no deleterious effects on antenna performance. Moreover, when coupling the MMIC amplifier to an unbalanced coaxial line, any associated ripple is minimized due to the direct connection.

1. A system for reducing parasitic and other losses due to the separation of antenna feed points from electronics connected thereto, comprising:
a bi-cone antenna having balanced feed points; a microelectronics circuit positioned across the balanced feed points of said antenna, said microelectronics circuit having a balanced connection thereto; and, a direct connection from the balanced connection to said microelectronics circuit and said balanced feed points, whereby losses and parasitic effects associated with electronics removed from said antenna feed points are reduced as compared to a case in which a signal source is fed to the antenna through a coaxial cable that is connected directly to the balanced feed points.
