High Gain Microstrip Patch Antenna for Biomedical Applications

This paper presents the design of microstrip patch antenna with high gain that can be used in tetra hertz frequencies. In the proposed antenna design, the substrate of material FR4 which possess the dielectric constant of 4.4 has been used. The microstrip feed line is used in the proposed antenna design. The proposed antenna design is the high gain patch antenna that has the resonant frequency of 0.125THZ. The parameters through which the performance of the antenna can be measured are impedance bandwidth (THz), return loss (db), directivity, gain (db), VSWR and impedance (ohms). The propounded antenna design can be used for biomedical application for the detection of various diseases. The antenna simulation has been performed by using HFSS.
