Effect of Two Different Superstrate Layers on Bismuth titanate (BiT) array antennas
The microwave industry has shown increasing interest in electronic ceramic material (ECM) due to its advantages, such as light weight, low cost, low loss, and high dielectric strength. In this paper, simple antennas covered by superstrate layers for 2.30 GHz to 2.50 GHz are proposed. The antennas...

| Summary: | The microwave industry has shown increasing interest in electronic ceramic material (ECM) due to its
advantages, such as light weight, low cost, low loss, and high dielectric strength. In this paper, simple
antennas covered by superstrate layers for 2.30 GHz to 2.50 GHz are proposed. The antennas are compact
and have the capability of producing high performance in terms of gain, directivity, and radiation efficiency.
Bismuth titanate with high dielectric constant of 21, was utilized as the ECM, while the superstrate layers
chosen included a split ring resonator and dielectric material. The superstrate layers were designed for some
improvement in the performance of directivity, gain, and return loss. The proposed antennas were
simulated and fabricated. The results obtained were small antennas that possess high gain and high
directivity with 3606, omni-directional signal transmission that resonant types of conventional dipole
antenna cannot achieve. The gain of the antenna with the superstrate layer was enhanced by about 1 dBi over
the antenna without a superstrate layer at 2.40 GHz. |
