Antenna - GPS PATCH

A GPS patch antenna is a type of antenna commonly used in GPS systems for receiving signals from satellites. It is called a "patch" because of its flat, rectangular, or square shape, which resembles a patch. Here’s a detailed description of it:

Design and Structure:

• Flat and Compact: GPS patch antennas are small and flat, typically made from materials like ceramic or printed circuit boards (PCBs).
• Shape: They are usually square or circular, with the patch itself sitting on top of a ground plane. This design allows for good signal reception while maintaining a low profile.
• Feed Mechanism: The antenna has a feed point where it connects to the GPS receiver, usually located at the center of the patch.
