![]() ![]() If you would rather import a drawing file instead, I can provide a DXF file containing the outlines for the three ground planes and the main element.Īdding the antenna pattern to an existing custom pattern libraryġ) Copy the pattern library file named " antenna.lib" (attached below) to your desktop.Ģ) Launch the Pattern Editor, choose " Other Libraries" in the Current Library Group selection panel (left side of display), in the main menu click on " Library" and then select " Open." in the drop-down menu to bring up the Open dialog window.ģ) In the Open dialog window search for and select/highlight the new pattern library file named " antenna.lib" (now located on your desktop) and click on the button to add it to the library list.Ĥ) Now choose " User Patterns" in the Current Library Group selection panel and select/highlight the desired destination library.ĥ) Click on the Pattern Tools panel and select " Insert Patterns from Another Library." in the fly-out menu to bring up the Insert Patterns dialog window.Ħ) In the Insert Patterns dialog window choose " Other Libraries" in the Libraries drop-list, select/highlight the library named " antenna", make sure its one-and-only pattern named " 900MHz" is selected/highlighted and click on the button. in the pop-up menu).īe sure to double-check all dimensions and let me know how everything works out. When connecting to the antenna feed be sure to assign the antenna element to the same Net assigned to your transmission line (right-click on the element's outline and select Properties. The lone Static Via connecting the end of the short antenna element to the bottom copper pour should be the only object the DRC flags (ignore it). All Static Vias and copper pours were assigned to the same Net. Ground planes were replaced with copper pours, and Static Vias of the recommended hole size and spacing were added. Be sure to double-check the Net name after the merge.įYI: The antenna was created using Gerber files imported from the website link in the datasheet. When a pop-up menu appears after the second mouse click, choose to merge the two nets. (Change the grid size as needed for a more precise placement.) You can also rotate the antenna group if necessary using the bar.ħ) To connect the antenna's ground plane, use the Place Ratline tool to drag a ratline between one of the antenna's Static Vias and a pad or Static Via on your board belonging to the desired Net. You will notice that all of the antenna objects are already grouped together.Ĥ) Close the second instance of the PCB Layout editor containing the antenna.ĥ) In your board layout, right-click once in a blank part of the Design Area near the desired destination point for the antenna and choose Paste in the pop-up-menu.Ħ) With the antenna group still selected/highlighted, use the arrow keys to nudge it into the desired position on your board. Here's how to place it into your board layout.ġ) Launch the PCB Layout editor and open your board layout.Ģ) Open the antenna file named " AN91445.dip" in a second instance of the PCB Layout editor by double-clicking on it.ģ) Select all of the antenna objects in the Design Area ( Ctrl + A) and copy it to the clipboard ( Ctrl + C). If you are using an older version of DipTrace, I can provide the ASCII file upon request. Below you will find a DipTrace ( v3.1) PCB file named " AN91445.dip" with the antenna you need.
