Antenna design

Every antenna is unique and needs to be adapted to its environment

The antenna is an important component in any radio design. This means that it is very important to tune the
antenna correctly to achieve the best performance for the radio. If the antenna is not correctly tuned, a lot of
transmitter power is lost, the operating range is shortened and, interference problems increase.

the cut-and-paste approach is not recommended…

The antenna is probably one of RF component that its performance is heavily dependent on its environment such as proximity to metal, housing, shape, and size of the ground plane…etc. An untuned antenna less efficiency compared to a well-tuned antenna.

A well-tuned antenna means

  • Higher operating range
  • Less EMC issues
  • Good for the RF module
