Abstract:
|
A novel H-shaped patch antenna suitable for wireless and
satellite communications is presented. The new antenna has some advantages
compared to conventional microstrip patch antennas, such as
small size, a fewer number of modes, no harmonic resonance, and the
provision of pure reactive impedances at its harmonics that can result in
increasing the transmitter efficiency. The basic principles and design
procedure are introduced. Two antennas at two different frequencies, 4
and 10 GHz, are designed, fabricated, and measured. The measured
results show a good agreement with the predicted ones |
