Electromagnetically Coupled Microstrip Patch Antennas for High Frequency Sensing Applications

In this paper the analysis of the stacked patch antennas on two different substrates namely Arlon and Polymide at terahertz frequency is presented. The analysis is carried out with two parameters namely by varying the distance of separation of patches and varying the substrates. Electrical parameters like return loss, gain, and bandwidth are compared with conventional patch antenna at same resonant frequency. This proposed model is useful in applications like terahertz sensing and communications. Apart from applications the electrical performance of proposed model shows improvement in terms of gain and reflection for the substrate having low dielectric permittivity. The finite integral technique is used to analyze the proposed model by way of CST microwave studio a proven electromagnetic tool.
