Low noise integrated MMDS antenna and down converter

An integrated semi-parabolic antenna/down converter receiving system comprising:

• a semi-parabolic antenna,
• a pair of driven feed elements,
• a support boom formed of conductive material connected to said semi-parabolic antenna for holding said driven feed elements in the focal area of said semi-parabolic antenna, said support boom having a formed hollow interior,
• a down converter formed in an elongated shape to fit entirely within said formed hollow interior of said support boom, said down converter at least including:
• (a) a printed circuit board, said printed circuit board having a bottom ground plane, said printed circuit board having an input end,
• (b) a low noise amplifier located on said input end of said printed circuit board, said low noise amplifier having an input end, the input end of said low noise amplifier being electrically coupled to said driven feed elements,
• (c) an RF filter connected to the output of said low noise amplifier,
• (d) an input ground shield covering said low noise amplifier and said RF filter and electrically connected to at least said bottom ground plane of said printed circuit board, said input ground shield having a plurality of first grounding means. located thereon so as to abut against said conductive material of the formed hollow interior of said support boom in order to (1) establish an electrical ground connection therewith and (2) position said input end of said printed circuit board within said formed hollow interior, and
• (e) said printed circuit board having a second grounding means connected to said bottom ground plane so as to abut against said conductive material at the formed hollow interior of said support boom in order to (1) establish a ground connection to said conductive material of said formed hollow interior of said support boom and (2) position said printed circuit board within said formed hollow interior.
