How to Choose an embedded GPS antenna

A ceramic patch GPS antenna may fit mechanically but still perform poorly if it is too small, incorrectly orientated, placed near noisy electronics or installed in the wrong RF environment. This guide explains how to select an embedded GPS antenna before the PCB and enclosure are finalised, including antenna size, active gain, U.FL/I-PEX connection, ground-plane dependency and when an internal antenna may not be suitable.

EMBEDDED GPS/GNSS SELECTION PRACTICAL INTEGRATION GUIDE

To choose a GPS antenna for an embedded device, start with the receiver, PCB size, enclosure material, ground plane and antenna location.

Quick answer Selection checks Patch size Ground plane Active vs passive Connectors Placement Antenna selector

QUICK ANSWER Start with the integration constraints, not just the antenna size These five checks will eliminate many unsuitable options before detailed RF validation begins.

BEST GENERAL CHOICE Active ceramic patch Match the antenna to the receiver band and space available inside the product.
