Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
77 words
An antenna comprising: a ground plane having an aperture formed therein; a radiating patch formed on one side of the ground plane and separated
therefrom by a first dielectric; a feedline arranged on an opposite side of the ground plane and
separated therefrom by a second dielectric, such that signals are coupled between the
feedline and the radiating patch via the aperture; and a shorting strip connecting a side of the radiating patch to the ground
plane.
Claim 2
Dependent Claim
31 words
The anetenna of claim 1 wherein the shorting strip is connected to the
side of the radiating patch at a position selected to provide a desired performance
characteristic for the antenna.
Claim 3
Dependent Claim
57 words
The antenna of claim 1 wherein the feedline includes a first portion
and a second portion arranged such that an impedance seen from the feedline
referenced at the aperture includes a series combination of an equivalent impedance
representing the combined effect of the aperture and radiating patch, and an
impedance of the second portion of the feedline.
Claim 4
Dependent Claim
24 words
The antenna of claim 3 wherein the second portion of the feedline
serves as a tuning stub to provide impedance matching on the feedline.
Claim 5
Dependent Claim
35 words
The antenna of claim 3 wherein the aperture is configured such that a
real part of the equivalent impedance of the aperture and radiating patch is
substantially equivalent to a characteristic impedance of the feedline
Claim 6
Dependent Claim
39 words
The antenna of claim 3 wherein the second portion of the feedline is
configured such that the impedance of the second portion of the feedline offsets an
imaginary part of the equivalent impedance of the aperture and radiating patch.
Claim 7
Dependent Claim
105 words
A signal directing method for use in an antenna, the method
comprising the steps of: arranging a radiating patch of the antenna on one side of a ground plane
having an aperture formed therein, such that the radiating patch is separated from the
ground plane by a first dielectric; arranging a feedline on an opposite side of the ground plane such that
the feedline is separated from the ground plane by a second dielectric and signals
may be coupled between the feedline and the radiating patch via the aperture; and connecting a side of the radiating patch to the ground plane via a
shorting strip.
Claim 8
Dependent Claim
50 words
The method of claim 7 wherein the radiating patch is a rectangular
patch, and the step of connecting a side of the radiating patch to the ground plane via
a shorting strip further includes the step of positioning the shorting strip to provide a
desired performance characteristic for the antenna.
Claim 9
Dependent Claim
57 words
The method of claim 7 wherein the step of arranging a feedline further
includes arranging the feedline such that an impedance seen from the feedline
referenced at the aperture includes a series combination of an equivalent impedance
representing the combined effect of the aperture and radiating patch, and an
impedance of the second portion of the feedline.
Claim 10
Dependent Claim
28 words
The method of claim 9 further including the step of using the second
portion of the feedline as a tuning stub to provide impedance matching on the
feedline.
Claim 11
Dependent Claim
38 words
The method of claim 9 further including the step of configuring the
aperture such that a real part of the equivalent impedance of the aperture and
radiating patch is substantially equivalent to a characteristic impedance of the
feedline.
Claim 12
Dependent Claim
42 words
The method of claim 9 further including the step of configuring the
second portion of the feedline such that the impedance of the second portion of the
feedline offsets an imaginary part of the equivalent impedance of the aperture and
radiating patch.
