Design and performance analysis of a novel bipolar linear array with SRR antenna for highgain ISM applications

A new Bipolar Linear Array with SRR Antenna is proposed to achieve high gain in ISM applications compared with conventional base supplied CPW-fed antennas. The novelty of the proposed antenna design has some very critical parameters, such as a base thickness of 0.035 mm, the substrate thickness of 1.6 mm, copper as base material, and relative permittivity (εᵣ =4). As for comparison, the Bipolar array antenna shows a considerably larger gain of 5.2 dB at all measured frequencies from 2 GHz to 5 GHz. Moreover, the Bipolar Array Antenna shows the unidirectional energy radiation, which ensures the loss-free and effective transfer of data. These results validate that the proposed antenna design, along with superior gain and total performance for ISM applications as compared to the CPW-fed array antenna, is successful. Summary: The presented bipolar array antenna, thereby having a significant enhancement of gain compared with the CPW-fed array antenna, is much more superior.
