   Porcess drawing style :  dwg / dxf / igs /stp / pdf / picture/ real products 
   Silkscreen /Engraving : cdr / pdf / picture / ai
    
3. Cut holes :

 Our standard cut tolerance is ±0.2 mm but tighter tolerances can be met when required. Extrusion is available as bars or cut-to-length
(marked, deburred, and ready for installation).We can drill holes through any of our housings to meet your specific requirements.
Our CNC processing center enables us to carry out difficult machining work to tight tolerances. From a nominal dimension
(both size and location) our CNC equipment tolerance is ±0.1mm. We are capable of holding ±0.2 mm with high process
capability on dimensions of size (hole diameter).

An internal active GPS Patch Antenna with cable is used in most mobile devices today that require high signal strength in a small form factor. It is the highest performing solution of all antenna types.

Usually consisting of a specially formulated dielectric ceramic, a trace is printed on the substrate to get the desired right hand circularly polarized Patch Antenna topology. The patch is mounted on a PCB; underneath the PCB is the Low Noise Amplifier (LNA) which amplifies the GPS signal before being transmitted through the coaxial cable and connector to the receiver.

This design application note is intended to help the antenna integrator understand the relevant parameters affecting the antenna performance.
Yetnorson recommends that the integrator strictly follow the guidelines in this application note. Upon your device prototype completion, Yetnorson can provide further optimization by offering custom tuning and testing services for the antenna in your device.

Gps Patch Antenna Description:

- Central frequency: 1575.42 MHz
- 8 cm cable
