I hereby certify that I am not simply asking someone else to design a footprint for me.
This is an auto-generated message that is in place on the “footprints” section of the KiCad.info forum. If I remove it and ask for a footprint to be designed anyway, I understand that I will be subject to forum members telling me to go design my own footprint or referring me to a 3rd party footprint site.
Hi! This is my first participation on the forum. My apologies for any mistake.
I’m creating the symbol and footprint of Unictron’s AA088 TELA chip antenna (https://www.unictron.com/wp-content/uploads/Unictron_AA088_GNSS_Chip_Antenna_F.pdf). The problem is that pin 1 of the TELA chip antenna family is both connected to the feed point and ground, causing a short circuit. This is done on purpose. The idea is to form a loop around the antenna so that the ambient ground can be used to increase the radiation area, and therefore, the electrical performance of the antenna (https://www.unictron.com/technology/tela-type-chip-antenna/). However, this will create problems for the DRC, right?! Is there a way to create these footprint and symbol so as to avoid problems with the DRC?
For the symbol, I just indicated the connection to ground, as I think I cannot create a duplicate pin.
The footprint is as below (drawn with the aid of the Custom Shape Primitives). I did not draw the grounding pin and the feed point (signal input) by extending pin 1 to the border of the keep out zone. I don’t know how to deal with this short circuit.
