| Summary: | A novel printed diversity monopole antenna is presented
forWiFi/WiMAX applications. The antenna comprises two
crescent shaped radiators placed symmetrically with respect to a
defected ground plane and a neutralization lines is connected between
them to achieve good impedance matching and low mutual
coupling. Theoretical and experimental characteristics are illustrated
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 obtained
for the computed and measured gain, radiation patterns,
envelope correlation coefficient, and channel capacity loss. These
characteristics demonstrate that the proposed antenna is an attractive
candidate for multiple-input multiple-output portable or mobile
devices. |
