Travelling wave slot array antenna

Extended Interactive Klystron. Traveling-wave tube.Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide. A Double-Layer Shaped-Beam Traveling-Wave Slot Array… The double-layer SIW longitudinal slot-coupled cavity slot is proposed as the array element, which has an improved bandwidth performance due to the double-resonant feature. By using this kind of slots, a planar nonuniformly spaced shaped-beam traveling-wave array is constructed.

Compared to the Resonant waveguide slot array, the Traveling wave slotted guide array has some impressive advantages. It can handle higher power and operates over a much wider band (up to 25% bandwidth), where the resonant array suffers from a decreasing bandwidth as the number of elements (and hence gain) increases, whilst this array does not. Optimum Design of Traveling-Wave SIW Slot Array Antennas Slot array antennas can be classified into two types: standing-wave-fed and traveling-wave-fed [6]. The impedance bandwidth of the standing-wave-fed slot arrays reduces quickly as the number of Traveling-Wave Slot Antennas - IEEE Journals & Magazine The traveling-wave slot antenna is similar to a traveling-wave wire antenna, but it is far more versatile because the phase velocity and rate of radiation Traveling-Wave Slot Antennas - IEEE Journals & … Theory of a Traveling Wave Feed for a Planar Slot Array

The narrow-wall slot array is a popular microwave frequency antenna, which is especially useful for RADAR applications where mechanical robustness, low-loss and the ability to withstand high transmit power are advantageous.

A linear slot array at $X$ -band is designed, simulated and fabricated for verification.This paper presents an optimum design method based on the Method of Least Squares (MLS) for the traveling-wave substrate integrated waveguide (SIW) slot array antenna.

MM-wave multi-beam slot array antenna Abstract: A planar multibeam slot array operating in the MM-wave range was designed and built. The slot array consists of 440 axial slots distributed in 20 columns of 22 slots each. Each column is of a travelling wave type. Experimental data is brought to validate the theoretical analysis. traveling-wave antenna array — с английского на русский 3 traveling-wave antenna array.
