I am trying to build a PCB antenna similar to what is shown in this video. At the 6:24 mark it shows the circuit layout below:
I am using Eagle to layout the PCB on a two layer board. Red is copper on the top of the board and blue is copper on bottom of board.
I am using a part from a library for an antenna mount. This mount is so that this PCB antenna can connect to a separate transceiver Lora board. The center pin is the signal feed. The other four pins are (I'm guessing here) the ground. I have attempted to layout the circuit myself.
Here is the schematic and the board.
The connector is shown on the info layer as being to right angle of board, but the connector fits for a variant which has the connector straight up towards viewer.
The vias were added and a ground plane in blue beneath the lower portion. The vias connect to the bottom ground plane but not the the top layer Ant signal connected to signal feed center pin. During bring-up these can be used forexperimentation by hand soldering via on top. These vias were added according to Figure 3 sub figure A in this wikipedia link.
In the video, he is showing the four ground pins with the heavy bold vertical lines by the antenna mount. Are these "gnd" or "mount" pins connected to the signal pin? I think not.
So the final question is, is the net/signal name "Ant" which is the entire top pour region and the center pin, also connected to the four pads for the antenna "ground," or should it be implemented as shown in the layout?
