Abstract
High antenna directivity is generally desirable for wireless
communication systems, whether terrestrial or based on satellites. Most of the
solutions proposed for improvement of the directivity of microstrip patch
antennas were to design array of several antennas. The particular disadvantage
of this method comes from the feeding of each antenna and also from the
coupling between each element. A suitable model to eliminate these two
disadvantages is to use a separate superstrate structure. For this purpose a
Left-Handed medium (LHM) superstrate used and presented in this study. Both the
reference antenna and proposed antenna are simulated, fabricated, and tested.
The simulation results show good agreement with the measurement results. It is
observed that the reference antenna directivity increased by 1.72 dB with the
proposed LHM superstrate according to the measurement results for 12 GHz
operating frequency
