Application 08/130,941
a coaxial feedline having a center conductor and a shield
at ground potential, said coaxial feedline terminating at one
end thereof at a feedpoint;
a continuous length of antenna wire having first and
second ends, said continuous length being electrically
connected at said first end to said center conductor at said
feedpoint;
a first portion of said continuous length formed from
concentric cylindrical coils of said antenna wire adjacent
said first end, each of said concentric cylindrical coils
defined by a plurality of adjacent turns of said antenna wire;
and
a second portion of said continuous length comprising an
antenna radiator extending from an innermost one of said
concentric cylindrical coils to said second end along a
substantially straight line on the surface, wherein said first
portion has an electrical inductance that can change
approximately linearly when said second portion is paid out
from said innermost one of said concentric cylindrical coils.
