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 notch mechanical. The down converter further includes a tunable dual band mechanical filter supported on the plate. The dual band mechanical filter and notch mechanical filter both include capacitance adjusting means adjustable by applying a mechanical screwing method whereby signal filtering efficiency is improved by reducing signal dissipation and the performance of the down converter is improved with the mechanically adjustable dual band and notch mechanical filters.
