摘要：

Electrically-small antennas can be designed using inductively-loaded dipoles. A simplified design procedure is carried out, using circuit models and EM simulations, to implement efficient dual and wide-band antennas with omni-directional radiation patterns. Measured performance agrees with simulations, and the proposed designs are employed for the UMTS 1.8/1.9/2.1/2.6-GHz and WLAN 2.4/3.6-GHz frequencies. A USB dongle antenna is prototyped to cover these frequency bands with impedance bandwidth reflection coefficient better than -10 dB.
