Ground plane
Why a big portion of PCB isn't filled with the ground plane ass shown with black colour except that whole PCB is filled with green colour.
This portion is nearby to D1 and C1 and is almost 30-35% of the whole PCB.

#### Answers:

Dear Learner,
Not adding a ground plane decreases the impedance. Also, there is connection of ground needed in the area where ground plane is not present.
Ground Plane is not an essential thing. A user may/may not add it.
