Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
241 words
A receiving antenna for a motor vehicle comprising: a base adapted to be fixed to the body of the said motor vehicle, mounting means secured to said base, said mounting means having an internal part made of insulating material, means defining a bore in said internal part with said bore extending through said base, said mounting means having an end remote from said base and another end with an antenna element fitted in said mounting means at said end thereof remote from said base, a first conductor element disposed at said another end and for connection to the core of a coaxial cable, said internal part having an external wall and a wire coiled about said external wall and connected to said external wall, said wire having opposite ends with one end connected to said antenna element and the opposite end connected to said first conductor element, said mounting means and said first conductor element having a cover made of insulating material with said internal part and said wire being nested within said cover, where the improvement comprises said antenna element and said first conductor element being electrically connected by electronic component means disposed in said bore and said electronic component means disposed in said bore and said electronic component means includes an inductor in series with a capacitor mounted in parallel with a diode, said diode being in the passing mode in the direction from said capacitor to said inductor.
