Abstract |
|
In this paper, basic concept and design process of the TE11 to HE11 mode converter in corrugated horn antenna is presented. In order to obtain optimum illumination at the aperture of a dual mode conical horn, as in the open cassegrain antenna it is necessary to control the relative amplitudes and phase of the TE11 and TM11 modes. The mode combination is established by exciting the dominant mode (TE11) in the circular wave-guide that feeds the horn, and converting into HE11 using variable-pitch-to-width-slot mode converter. It has advantage of low return loss and pattern symmetry for design frequency range. |
