Abstract
Slotted‐waveguide antennas with omni‐directional radiation patterns are analyzed using the 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 are shown to be in good agreement with those obtained from measurements. © 2001 John Wiley & Sons, Inc.

## Abstract A circularly polarized slotted array antenna is presented. The array is fed by a circular waveguide propagating the TM~01~, to properly generate the required polarization. An omnidirectional azimuth radiation pattern is obtained, as well as a −10°/+30° elevation antenna coverage. Low lo
## Abstract Slotted waveguide array is analyzed using the multilevel fast multipole algorithm (MLFMA) combined with the near‐field preconditioner applied to the metallic surfaces of the waveguide structure. The approach differs from existing methods that utilize asymptotic method, method of moments
