Slotted-waveguide antennas with omni-directional radiation patterns are analyzed using lite method of moments and a full-wall electromagnetic simulator based on the finite-difference time-domain (FDTD) method. The resonant and radiation properties of the antennas have been examined. The simulated results arc shown to be in good agreement with those obtained from measurements. © 2001 John Wiley & Sons, Inc.
