The Antenna Question
It’s Complicated:
How Much Space Should it Take?
What Kind of Antenna Should You Choose?
Should You use a Module with an Antenna Already Integrated?
8
The Antenna Question – How Much Space?
Typical Printed PCB Antennas Require
Lots of Space:
• Typically in the 25 mm x 15 mm Range
• Resulting in Large End Devices
• Sensitive to Detuning
9
The Antenna Question – What Kind Should I Choose?
Two Types of Chip Antennas:
• Antennas that are not coupled to the GND plane
and will require a relatively large clearance area
(or that is free from the ground, traces, and
components). Examples include monopole and
inverted –F type antennas.
• Antennas that are coupled to the GND plane and
require either a relatively small clearance area
beneath the antenna or don’t require clearance
area at all.
11
External Antennas and Housing Density
Choosing an External Antenna:
• Half of all IoT customers explore the possibility of
using an external antenna.
• Only 10 percent actually end up using one
Why?
• External antennas are not design-friendly
• Significantly increase BOM costs
• No efficiency gain with external antennas
• Only 10 percent actually end up using one
