High gain ultra wide band (UWB) multi resonant antenna for biomedical applications, security purposes and drug detection
This paper presents an ultra wide band (UWB) multi resonant optical antenna. In the proposed antenna design, substrates of material FR4 having dielectric constant 4.4 have been used. The aperture coupled feeding technique has been used in the proposed antenna design. The ground, patch and feed line are of copper material. The proposed antenna design is a multiband optical antenna having multiple resonant frequencies lying below the desired return loss of 10dB in 1.15 THz 7.97 THz frequency range. The performance of optical antenna has been analyzed in terms of impedance bandwidth (THz) return loss (dB) directivity (dBi) gain (dB) VSWR and impedance (ohms) The proposed antenna design has higher gain and directivity for higher resonating frequencies. The proposed antenna can be used for biomedical applications, security purposes (Explosives detection) drug detection and monitoring water content in leaves.
