circulator in a single...flared notch radiator.” Indeed, that
is the issue because this is what is now required by the
instant claims and, in our view, the examiner has not made a3
satisfactory showing of why such a single flared notch
radiator would have integrated thereon those elements recited
in the instant claims so that the radiating element itself
would have separate and isolated transmit and receive ports.
With regard to instant independent claim 17, this claim
additionally requires first and second dielectric sheets to
sandwich the flared end of the radiating element in order to
force the slotline to “operate as a coplanar slotline-type of
structure by concentrating fields.” While Figure 18 of
Sharma, employed by the examiner to teach this claimed
feature, may show a “sandwiching” provided by dielectric
sheets, these dielectric plates do not force an antipodal
slotline structure to operate as a coplanar slotline-type
structure, as required by instant claim 17. We find no
3While the claims do not specifically recite the term
“single,” it is clear from the claims that we deal with “An
integrated antipodal flared notch radiating element” and “the
integrated antipodal flared notch radiating element” [emphasis
ours], indicating that, indeed, it is a “single” radiating
element which is required.
