A new reflectarray cell using microstrip patches loaded with slots
05 February 2005
In this paper, a new reflectarray cell,consisting of a variable-length slot etched in a microstrip patch is presented. The phase shift is achieved by controlling the length of the slot. Two different structures are proposed: the first one uses a single patch with a single slot while the second involves three coupled patches sharing two slots. Good agreement between the simulations and measurements is obtained for passive structures designed at 5.7 GHz in a waveguide. (C) 2005 Wiley Periodicals, Inc.
