Abstract :
This paper summarizes the investigation of radiation from the slotline made on a thin low permittivity substrate. The slot radiates the space leaky wave of the first order. The dispersion characteristic of this wave is presented. Two versions of the antenna were designed, optimized and fabricated. The wide slot is fed by the microstrip patch in the first design, and by the CPW patch in the second design. The measured and calculated return loss and also the radiation patterns compare well for both the first and the second antenna.
