Microstrip patch antennas for terahertz sensing applications

Abstract

The Paper presents an investigation on electromagnetically coupled patch antennas on two different substrates namely Arlon and Polymide at terahertz frequency. The analysis is carried out with two parameters namely by varying the distance of separation of patches and varying the substrates. The electrical performance of the proposed models like return loss, gain, and bandwidth are compared at same resonant frequency. This proposed model is useful In applications like terahertz sensing and communications. The proposed model with dielectric substrate having low permittivity value shows the significance improvement in terms of gain and reflection. The analysis is carried out using finite integral technique by way of CST microwave studio a proven electromagnetic tool.
