Appeal No. 96-2408
Application No. 08/246,538
This is a decision on appeal from the final rejection of
claims 13 through 17 and 19 through 21, constituting all the
claims remaining in the application.
The invention is directed to an antipodal flared notch
radiator with separate transmit and receive ports.
Representative independent claim 21 is reproduced as
follows:
21. An integrated antipodal flared notch radiating
element for radiating energy into, or receiving energy from,
free space, said radiating element having separate, integral
transmit and receive connections which are isolated from each
other, said integral antipodal flared notch radiating element
comprising:
a planar dielectric board having first and second
opposed surfaces, the first surface having a first conductive
pattern formed thereon, the second surface having a second
conductive pattern formed thereon;
wherein said first and second conductive patterns
cooperate to define an antipodal slotline adjacent a flared
end thereof and a broadside coupled strip transmission line
region which transitions into said antipodal slotline, said
broadside coupled strip transmission line region formed by
first and second conductive strips overlying each other on
opposite sides of the dielectric board;
said first conductive pattern further defining first
and second microstripline conductors adjacent a
receive/transmit port end of said radiating element, said
first microstripline conductor comprising a transmit signal
connection integrated with said radiating element, said second
microstripline conductor comprising a receive signal
connection integrated with said radiating element;
