Abstract
Official abstract text for this publication.
An antenna comprising a network of arrayed radiating elements, a first reflective means comprising a flat central part upon which are disposed the radiating elements and longitudinally folded edges on either side of the array of elements, and at least one second reflective means which is a choke reflector disposed outside of the space separating the radiating elements of the reflector's folded edge. The second reflective means is separated from the first reflective means by a layer of dielectric material in order to connect it to the first reflective means by way of capacitive coupling.
First claim
Opening claim text (preview).
There is claimed: 1. An antenna comprising a network of arrayed radiating elements, a first reflector comprising a flat central part upon which are disposed the radiating elements and longitudinally folded edges on either side of the array of elements, and at least one second reflector, wherein the second reflector is a choke reflector disposed outside the space separating the radiating elements from the folded edge of the first reflector, and wherein the second reflector is U-shaped with two sidewalls, one of the sidewalls being separated from the first reflector by a layer of dielectric material between the second reflector and a surface of a longitudinal folded edge of the first reflector in order to connect it to the first reflector by way of capacitive coupling. 2. An antenna according to claim 1 , wherein the second reflector is a metal sheet folded into a U shape, with the outer surface of one of the arms of said U cooperating with the outer surface of a folded edge of the first reflector. 3. An antenna according to claim 2 , wherein the arms of the U are unequal in length. 4. An antenna according to claim 2 , wherein the metal sheet is made of aluminum. 5. An antenna according to claim 1 , wherein the second reflector means is disposed upon at least one part of the antenna's entire length.
