2. SYNTHESIS OF A LINEAR ARRAY ANTENNA Design of a linear array antenna incorporating waveguide longitudinal slots as radiators is described. Prior to the design of an array it is required to determine the resonant slot length, equivalent circuit and variation of the circuit parameters with the change in oﬀset value. ex W1GHZAntenna Book W1GHZAntenna BookW1GHZAntenna Book ... 7.2.3 Waveguide slot array design A sketch of a waveguide slot antenna with the pertinent dimensions is shown in Figure 7-5. The first design consideration is that the slots be resonant so that they provide a resistive load to the (waveguide) transmission line. Investigation and Design of a Slotted Waveguide Antenna ...
