碩士 === 國立臺灣大學 === 電機工程學系 === 85 === In an indoor radio environment plagued by the severe spatial
fading and temporal fading effects of multipath, diversity
schemes usually required. This thesis proposes a flat diversity
antenna, consisting of two cross-polarized dipole antennas
selectly excited by a PIN diode at the feeding point, to reduce
the fading effects in the indoor environment. Results presented
here provide a comparison between measurement and simulation
results of input impedance and radiation pattern. Parameters
studies of the antennas are also presented. To verify the
diversity effects of this antenna, measurement for propagation
characteristics was made in one of NTU EE laboratories at 2.4
GHz. The diversity gain is forward to be at least 3dB at 99%
signal availability.
