Design and Analysis Using PCB Antenna Designer App
This four-part tutorial shows how to design, validate, analyze, and export a 1-by-2 H-notch linear antenna array resonating at 4.65 GHz using the PCB Antenna Designer app. The fifth part of this tutorial allows you to recreate the same H-notch patch using variables for property values.
To design, validate, analyze, and export a 1-by-2 H-notch linear antenna array using the PCB Antenna Designer app, follow these four steps:
Define PCB antenna layers: Define PCB antenna layers for the metal patch, substrate, and ground plane for the 1-by-2 H-notch linear antenna array. For more information, see Define PCB Antenna Layers.
Design H-notch patch unit element: Design the H-notch unit element for a 1-by-2 H-notch linear array. You design the H-notch unit element by subtracting the top and bottom notches from the substrate. Add a feed on the H-notch unit element to excite the antenna and validate your board shape, layers, feed, via, and load. For more information, see Design H-Notch Patch Unit Element.
Analyze H-notch unit element: Perform vector frequency analysis to calculate the impedance and the S-parameters over the frequency range of the PCB antenna and scalar frequency analysis to calculate the current distribution, 3-D pattern, and azimuth and elevation patterns of the PCB antenna. For more information, see Analyze H-Notch Unit Element.
Design, analyze, and export 1-by-2 H-notch linear array: Design a 1-by-2 H-notch linear array with the H-notch patch as its unit element. Add the feed and validate the design before analysis. Analyze the design to confirm that it satisfies the design goals and export the design to Gerber files for the fabrication of the PCB patch antennas. For more information, see Design, Analyze, and Export 1-by-2 H-Notch Linear Array.
Design and analyze H-notch patch using design variables: Design the same H-notch patch using variables for the properties of the board, metal layers, and patch. You can add the variables using the Design Variables tab. Analyze the design to see that the results match the pervious patch.
