Forward (broadside) directivity for the 5-slot array of the dual-sided slotted waveguide array, and the change in the directivity in the backward direction as its array is populated with slots. “Zero” slots (left-most side) means that the array is the single-sided configuration. The reflection coefficient in dB of the antenna is shown Sidewall Waveguide Slot Antenna for High Power Sidewall Waveguide Slot Antenna for High Power Carl E. Baum University of New Mexico Department of Electrical and Computer Engineering Albuquerque New Mexico 87131 Abstract This paper discusses a concept for high-power microwave antennas based on an array of slots in the sidewall where the electric fields are lower.

In a flat plate antenna, insertion loss is reduced significantly by providing an extensive waveguide structure at the back of the ground plane of the antenna. Depending on antenna size, the waveguide may feed the antenna at one or a …

Slot offset 9.2 mm Rectangular waveguide wide side 94 mm Fig. 5(c). 3D Radiation pattern for the slotted rectangular waveguide array antenna The patch-rod antenna has been simulated and analyzed using The slot array antenna is designed with 8 numbers of slots by using a substrate copper with specifications 5.8x107 S/m Ansys HFSS V14.0.
