Abstract: In this paper, a new waveguide slotted antenna array, in which T-shaped cross section waveguide is used as the radiating waveguide, is proposed and simulated. The T shaped radiating waveguide can reduce the waveguide profile height. The radiating slots are etched and inclined alternately on the top [1, 2, 3]. The metal fences are introduced between slots to repress the sidelobe level of E-plane [4]. A bend structure is invented to feed the T-shaped radiating waveguide [3, 5]. A 2 6 antenna array working at Ka-band is designed and the obtained simulated results demonstrate this novel structure.
