PCB Trace vs Chip Antenna Design Considerations
The modern urban environment poses a challenge to high-speed designs involving Cellular, GNSS, WiFi/ Bluetooth/BLE/ZigBee and LPWA protocols: the reflection, refraction, scattering, diffraction, polarization and absorption of signals necessitates highly efficient RF chains. Of all components in the chain, the antenna has the key role in establishing wireless connectivity. A PCB trace antenna is given serious consideration when attempting to reduce the overall system cost; however, chip antennas offer better overall performance in terms of size selectivity and efficiency in most cases. The following information outlines the attributes of both chip and PCB trace antennas. It also covers the design considerations required in selecting the right type of antenna to implement in your design.
