Abstract
The present invention discloses an integrated dipole antenna and down converter apparatus. The integrated dipole antenna and down converter apparatus includes a dipole antenna for receiving microwave signals therein. The integrated dipole antenna and down converter apparatus further includes a down converter for receiving processed signals of the microwave signals from the dipole antenna for converting the processed signals to signals of lower frequency. The down converter includes main plate for supporting a tunable mechanical filter. The down converter further includes a tunable semi-mechanical filter supported on the plate. The semi-mechanical filter includes an upper circuit assembly and an identically symmetrical lower circuit assembly for canceling electromagnetic waves transmitting in the upper and lower circuit assemblies and the main plate whereby signal filtering efficiency is improved by reducing signal dissipation in the upper and lower circuit assemblies. In a preferred embodiment, the integrated dipole antenna and down converter apparatus further includes a housing for containing the down converter. The housing and the upper and lower circuit assemblies defining an up…
