Abstract:
A dual band printed inverted-F antenna with a nested structure is proposed. In this antenna, matching can be controlled for both frequency bands by changing element lengths. The measured and calculated frequency characteristics of the antenna's reflection coefficient match very well, if the measurement cable connector is considered in the simulation. The measured -10 dB relative bandwidths of the reflection coefficient are 4.7% at 2.45 GHz (2.5 GHz to 2.62 GHz), and 9% at 5.5 GHz (5.28 GHz to 5.78 GHz). The calculated radiation efficiencies are 92% and 88%, at 2.45 GHz and 5.5 GHz, respectively, with calculated peak realized gains of 1.07 dBi and 3.36 dBi, respectively.
