Re: Part II: Picking the Right MCU for Your Application

Q: With the differnet wireless protocols that use the same frequency (ZigBee, Fi, Bluetooth) at 2.4 GHz, do they all use the same antenna types, or are there differences from the different protocols?

A:  The frequency rather than the protocol, defines the antenna needed.  So, any radio that operates at 2.4 GHz uses an antenna with the same characteristics as any other radio at 2.4 GHz.  There are different radio-antenna configurations, such as chip antennas, short-wire antennas, Yagi antennas, and so on.  The type of antenna depends on your application and whether you want directional or unidirectional performance, gain, etc.
