4.2. Antenna connection

Proteus-III's smart antenna configuration enables the user to choose between two antenna
options:

4.2.1. On-board PCB antenna

The Proteus-III has an on-board PCB antenna optimized for strong miniaturization operating in
the 2.4 GHz frequency band. A simple short between the pins RF and ANT feeds the RF output
of the module to the on-board antenna of the Proteus-III. In this configuration, the module does
not require any additional RF circuitry. For US and Canada, please refer to the trace design in
chapter 17.2 .

4.2.2. External antenna

For applications that use an external antenna, the Proteus-III provides a 50
pin RF of the module. In this configuration, pin ANT of the module has to be connected to
ground and pin RF to the external antenna via 50
information.
The use cases for the integrated antenna are miniaturization and re-use of
module certifications for the end-application. The use cases for the external
antenna are optimization of radio range spending more space for the antenna
and differentiated antenna for example when metal housings are used.
