| Abstract | The design, construction, and performance of two stripline antenna arrays to be used as fixed beam altimeter antennas is described. These traveling wave arrays contain 8 X 10 and 16 X 21 series slots, respectively, and employ combination series-parallel feeds. The parallel feed junctions are folded onto the rear of the antenna using resonant slot coupling. Each row of series slots is terminated by a series flat load involving no ground plane connection. Design data to give the required resonant slot resistances were computed from an expression which includes the effect of internal, but not external coupling, and transmission line attenuation between slots. |
