createFeed
Create feed location for custom antenna
Description
createFeed(
plots
a custom antenna mesh in a figure window. From the figure window,
you can specify a feed location for the mesh and create a custom antenna.
To specify a region for the feed point, select two points, inside
triangles on either side of the air gap or inside triangles that share
a common edge.antenna
)
createFeed(
creates
the feed across the triangle edges identified by antenna
,point1,point2
)point1
and point2
.
After the feed is created, when you plot the resulting antenna mesh
the feed location is highlighted.
Input Arguments
Examples
Create Feed for Custom Mesh Antenna Using Air Gap between Triangles
Load a 2-D custom mesh. Create a custom antenna using the points and triangles.
load planarmesh.mat
c = customAntennaMesh(p,t)
c = customAntennaMesh with properties: Points: [3x658 double] Triangles: [4x1219 double] FeedLocation: [] Tilt: 0 TiltAxis: [1 0 0]
Use the createFeed
function to view the
antenna mesh structure. In this antenna mesh view, you see Pick and Undo buttons.
The Pick button is highlighted.
createFeed(c)
Click Pick to display the cross-hairs. To specify a region for the feed point, zoom in and select two points, one inside each triangle on either side of the air gap. Select the points using the cross-hairs.
Selecting the second triangle creates and displays the antenna feed.
Create Feed for Custom Mesh Antenna Using Triangles Sharing Edge
Load a 2-D custom mesh. Create a custom antenna using the points and triangles.
load planarmesh.mat
c = customAntennaMesh(p,t)
c = customAntennaMesh with properties: Points: [3x658 double] Triangles: [4x1219 double] FeedLocation: [] Tilt: 0 TiltAxis: [1 0 0]
Use the createFeed
function to view the
antenna mesh structure. In this antenna mesh view, you see Pick and Undo buttons.
The Pick button is highlighted.
createFeed(c)
Click Pick to display the cross-hairs. To specify a region for the feed point, zoom in and select two points, one inside each triangle sharing an edge. Select the points using the cross-hairs.
Selecting the second triangle creates and displays the antenna feed.
Create Feed for Custom Antenna Mesh
Load a 2-D custom mesh using the planarmesh.mat. Create a custom antenna using the points and triangles.
load planarmesh.mat
c = customAntennaMesh(p,t)
c = customAntennaMesh with properties: Points: [3x658 double] Triangles: [4x1219 double] FeedLocation: [] Conductor: [1x1 metal] Tilt: 0 TiltAxis: [1 0 0] Load: [1x1 lumpedElement]
show (c)
Create the feed for the custom antenna across the points (0.07,0.01) and (0.05,0.05) meters respectively.
createFeed(c,[0.07,0.01],[0.05,0.05]) show(c)
