Appeal No. 2001-1304
Application No. 09/061,392
BACKGROUND
The disclosed invention is directed to a folded monopole antenna using two
vertical monopole elements, one of which is tapered and resistively loaded to a ground
plane. According to appellant, the tapered monopole antenna element causes a
cancellation of the electric field from the feeding (non-tapered) antenna element, to
thereby provide a wide range of impedance matching. Representative claim 1 is
reproduced below.
1. An antenna apparatus comprising:
a first monopole antenna element having an outer diameter that varies
between a base end thereof and a top end thereof;
a second monopole antenna element having an outer diameter that is
substantially constant between a base end thereof and a top end thereof, and
a third antenna element having an outer diameter that is substantially
equal to said outer diameter of said second monopole antenna element, said
third antenna element being operably coupled to said top ends of said first and
second monopole antenna elements.
The examiner relies on the following references:
Saari 3,229,296 Jan. 11, 1966
Goodman 4,161,736 Jul. 17, 1979
Claims 1-7 and 10-16 stand rejected under 35 U.S.C. § 103 as being
unpatentable over Goodman and Saari.
We refer to the Final Rejection (Paper No. 6) and the Examiner’s Answer (Paper
No. 13) for a statement of the examiner’s position and to the Brief (Paper No. 12) and
