Abstract
Abstract An antenna having a "suspended stripline" structure with two metal plates encircling a dielectric film is disclosed. In this structure, a channel is made for a feeder of a slot with the end of a central conductor of the line penetrating a cavity whose thickness is approximately equal to that of the channel. The slot is made in the upper wall of the cavity.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
89 words
A slot hyperfrequency thin antenna including a suspended stripline type structure comprising: a feeder having two plates of electrically conductive material with a dielectric film inserted between said plates and a channel formed therein; a stripline having a core in said feeder, the end of the core penetrating a cavity, one of said plates having at least one slot extending through said one plate to form an opening into said cavity, with the depth of the cavity being approximately equal to the thickness of said channel of the feeder.
Claim 2
Dependent Claim
89 words
A slot hyperfrequency thin antenna including a suspended stripline type structure comprising: a feeder having two plates of electrically conductive material with a dielectric film inserted between said plates and a channel formed therein; a stripline having a core in said feeder, the end of the core penetrating a cavity, one of said plates having at least one slot extending through said one plate to form an opening into said cavity, with the depth of the cavity being approximately equal to the thickness of said channel of the feeder.
Claim 3
Dependent Claim
20 words
Antenna according to claim 1, further comprising a partial reflector placed parallel to said plate having at least one slot.
Claim 4
Dependent Claim
30 words
Antenna according to any one of claims 1 or 2, wherein the end of the core of the stripline is short-circuited with the wall of an end of the cavity.
Claim 5
Dependent Claim
20 words
Antenna according any one of claims 1 or 2, wherein the end of the core of the stripline is open-circuited.
Claim 6
Dependent Claim
15 words
Antenna according to any one of claims 1 or 2, wherein the slot is rectilinear.
Claim 7
Dependent Claim
21 words
Antenna according to one of the claims 1 or 2, wherein the ends of said at least one slot are folded.
Claim 8
Dependent Claim
27 words
Antenna according to any one of the claims 1 or 2, wherein the longitudinal axis of the feeder is offset relative to the longitudinal axis of cavity.
Claim 9
Dependent Claim
27 words
Antenna according to any one of claims 1 or 2, wherein the end of the core of the feeder is offset relative to middle (M) of slot.
Claim 10
Dependent Claim
23 words
Antenna according to any of claims 1 or 2, wherein the width of the end of the core of the feeder is variable.
Claim 11
Dependent Claim
29 words
Antenna according to any one of the claims 1 or 2, wherein the thickness of the end of the channel of the feeder and/or of the cavity exhibit variations.
Claim 12
Dependent Claim
44 words
Antenna according to any one of the claims 1 or 2, wherein said dielectric film comprises metallized holes on the circumference of said channel and/or cavity, putting into electric contact the two electrically conductive plates of the stripline around the cavity and/or the channel.
Claim 13
Dependent Claim
33 words
Antenna according to any one of the claims 1 or 2, wherein at least the end of the core of the stripline comprises a double face metallization of the film of the stripline.
