Abstract

The proposed antenna is a transparent water dense dielectric patch antenna which is fed by an L-shaped probe. The operating mechanism of the proposed antenna is similar to the standard metallic patch antenna. A study reveals that the gain of the antenna can be increased if the water patch is brought close to the L-shaped probe but the distance between the water patch and the L-shaped probe should be at least 1 mm. A maximum gain of 7.3 dBi, return loss of 18.4 dB and impedance bandwidth of 575 MHz was achieved. It had symmetrical unidirectional patterns.
