This work present the experimental assessment of frequency bandwidth limits on 2x2 cm antenna embedded in a 5x5cm terminal at 900MHz. A meander Inverted F antenna is synthesized, prototyped and measured. The operating frequency bandwidth and radiation efficiency are extracted from radiation measurement. Comparison with optimal bounds on the Q-factor show that this structure can reach close to the bandwidth fundamental limit.
