Abstract

In this paper, Design of the Offset Radiation Tapered Slot Antenna is presented. The proposed antenna is characterized by total size of 58*64 mm2 printed on a dielectric substrate of FR4 with 1 mm thickness. A rectangular slot is inserted in order to enhance the antenna gain by changing the distribution of current. The antenna is found to operate in the range ≥1.9 GHz with S11 ≤-10dB which satisfying the ultra-wideband region. Moreover, the VSWR variation with respect to frequency is found less than 2 in the frequency band from 1.9 GHz to more than 12 GHz. The gain is enhanced in all operating frequency band with 1.75 dB as a maximum enhancement value at 4GHz. The proposed TSA offers an offset phase shift about 30o from the endfire direction. This offset shift is important for many applications that are required to reduce the aperture block and can reduce the coupling between antennas for MIMO antenna design.
