One of the crucial factors determining an antenna's performance is its bandwidth. The -10dB Bandwidth for GPS L1 is a minimum of 22MHz, while for GPS L5, it is a minimum of 3MHz. This wide bandwidth ensures that the antenna can handle a broad range of signals, contributing to more accurate and reliable navigation.

To maintain signal integrity, the VSWR (Voltage Standing Wave Ratio) within the bandwidth is kept below 1.8, ensuring minimal signal loss and reflections. This helps in achieving a stable and consistent connection with satellite systems.

For optimal performance, the Ground Plane Size plays a vital role. For GPS L1, the ground plane size is measured at 64.76×37.64 mm, while for GPS L5, it is 65.36×70.88 mm. A properly sized ground plane provides a stable platform for the antenna, facilitating efficient signal transmission and reception.

The Dimension of Patch Antenna is also carefully designed to optimize signal capturing capabilities. With dimensions of 25x25x4(H) and 18x18x4(H), the patch antenna is engineered to efficiently receive and process signals from various navigation satellites.
