Summary: | A novel printed diversity monopole antenna is pre�sented for WiFi/WiMAX applications. The antenna comprises two
crescent shaped radiators placed symmetrically with respect to a
defected ground plane and a neutralization lines is connected be�tween them to achieve good impedance matching and low mutual
coupling. Theoretical and experimental characteristics are illus�trated for this antenna, which achieves an impedance bandwidth of
54.5% (over 2.4–4.2 GHz), with a reflection coefficient 10 dB
and mutual coupling 17 dB. An acceptable agreement is ob�tained for the computed and measured gain, radiation patterns,
envelope correlation coefficient, and channel capacity loss. These
characteristics demonstrate that the proposed antenna is an attrac�tive candidate for multiple-input multiple-output portable or mo�bile devices.
