Abstract :
Present paper describes the design, simulation, optimization and development of a dual mode horn at 140 GHz. The operating bandwidth of the antenna is more than 10 GHz. The antenna has low side lobe level and low cross polarization. It has been used as a feed horn for dielectric lens antenna developed for passive millimeter wave imaging sensor.
