GPS built-in antennas are usually divided into two main types: ceramic patch antennas and FPC antennas (flexible printed circuit antennas). They each have their own advantages and disadvantages, as follows:

1. Ceramic patch antenna

characteristic:

Material: Made of high-frequency ceramic material, usually in the shape of a rectangular patch.

Performance: Strong signal reception capability, especially in situations with large antenna sizes, suitable for higher requirements.

Size: Typically large in volume, ranging from 10mm x 10mm to 25mm x 25mm, with thickness varying from 1.5mm to 4mm.

Directionality: It has good directionality, but has high requirements for installation methods, installation angles, and surrounding environment.

Application: Widely used in devices that require high-precision positioning, such as car GPS devices, navigation systems, drones, etc.

advantage:

High signal sensitivity and good positioning accuracy.

Strong adaptability to temperature and environment, good anti-interference performance.

Disadvantages:

The size is large and not suitable for miniaturized equipment.

The cost is relatively high.

2. FPC antenna (flexible printed circuit antenna)

characteristic:

Material: Made of flexible circuit board material, very thin in thickness and bendable.

Performance: The signal reception capability is slightly weaker compared to ceramic patch antennas, but it still has good reception capability for small devices.

Size: Small in size, typically ranging from 0.1mm to 0.5mm in thickness, with high flexibility to accommodate installation spaces of different shapes.

Directionality: The signal directionality is weak, but it is suitable for devices with complex structures or limited space.

Application: Widely used in mobile devices that require miniaturization and lightweight, such as smartphones, watches, GPS trackers, etc.

advantage:

Small size, light weight, suitable for compact and portable devices.

Low cost, easy to mass produce and apply to various devices.

Disadvantages:

The signal reception sensitivity is relatively weak, especially in environments with interference, where it performs poorly.

The adaptability to the environment is not as good as that of ceramic patch antennas, and they are easily affected by factors such as temperature and humidity.
