Design of traveling wave slotted waveguide array antenna with high efficiency

Design of Millimeter-wave Slotted-Waveguide Planar Antenna for Sub-array of Beam-scanning Antenna

Beam-scanning antennas are attractive for high-bit-rate data communication systems and high resolution sensing systems in millimeter-wave band. Waveguide antenna is one of the most attractive antennas for such millimeter-wave systems because of its low loss and high efficiency characteristics in high frequency band. Horizontally-beam-scanning antennas such as phased arrays and DBF (Digital Beam...

A Wideband Slotted Waveguide Antenna Array for Sar Systems

Possibilities for the extension of the operational frequency band of slotted waveguide antennas are studied. It is shown that by using both conventional longitudinal slots and subarraying techniques it is possible to reach the relative bandwidth of about 15%. This result is illustrated by the development of a novel slotted waveguide antenna for high-resolution SAR applications. The antenna oper...

designing and simulation of a wide-band mono-pulse slotted waveguide antenna array

in this paper, a resonant slotted waveguide array antenna with circular boundary has been designed and simulated for mono-pulse airborne radar applications. the antenna parameters are:11% bandwidth in x-band (8.6-9.6ghz),vswr < 2, 38dbi directivity, sidelobes level of - 20db and 3-db beam-widths of 2.1degree. to design this antenna, it is divided into short sections (sub-arrays) each with a uni...

Slotted Waveguide Antenna Design Using 3D EM Simulation

Slotted waveguide antennas (SWA) are often employed in radar applications where design specifications commonly require high gains and mechanical robustness. Since the peak power transmitted by radar antennas is usually very high, waveguide antennas present a practical alternative to planar arrays. While numerous design references and guidelines exist for planar arrays, there are far fewer for s...
