Abstract :
The aim of this work is to reconfigure the radiation pattern of tapered slot antennas (TSA) by switching between two different types of tapering. Constant width slot antennas (CWSA) are known to have narrower beamwidth and higher sidelobe level whereas linearly tapered slot antennas (LTSA) have wider beamwidth with lower sidelobe level compared to each other. A CWSA and a LTSA operating at millimeterwave band are designed together with their feed structures. EM simulations of these two antennas are performed and their radiation characteristics are compared to explore the potential of TSA for radiation pattern reconfigurability.
