2.4-GHz Inverted F Antenna
ABSTRACT
This document describes a printed-circuit board (PCB) design that can be used with all 2.4-GHz
transceivers and transmitters from Texas Instruments™. The maximum gain is measured to be +3.3 dBi,
and the overall size requirements for this antenna are 25.7 × 7.5 mm. Thus, this antenna is compact, low
cost, and high performance.
