Miranda NASA John Glenn Research Center Cleveland, OH, USA Abstract—This paper introduces a feeding concept aimed at Non-Resonant Slotted Waveguide Antenna Design Method ANTENNA DESIGN I n this paper a non-resonant slotted waveguide antenna design method is present-ed. The internal and external mutual coupling between adjacent radiat-ing slots is considered in the described meth-od. In order to confirm the usefulness of this method, a non-resonant waveguide array antenna with longitudinal slots cut in a broad 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 ... Travelling Wave, Broadband, and Frequency Independent Antennas Travelling Wave, Broadband, and Frequency Independent Antennas Slide 25. In the 1950s, there was a breakthrough in antenna evolution that drove antenna designs to a bandwidth as great as 40:1 or even more. These antennas have a variety of practical applications such as TV, point-to-point communication, feeds for reflectors and lenses, etc.

Long Wire and Traveling Wave Antennas 13-3 Fig 2—Angles at which radiation from long wires is maximum (solid curves) and zero (broken curves). The major lobe, no. 1, has the power gains given by Fig 1. Secondary lobes have smaller amplitude, but the maxima may exceed the radiation intensity from a half-wave dipole. A travelling-wave fed parallel plate slot array antenna with ... The paper demonstrates a travelling-wave parallel plate slot array antenna capable of generating inclined linear polarisation with good cross-polarisation characteristics at 60 GHz, taking advantage of the rotated series slot elements, in order to reduce the interference from other systems. Compact millimeter‐wave switched‐beam antenna arrays for ... years, millimeter-wave technology has generated much excitement in the mobile and wireless communications sectors due to the large bandwidth it can offer. In this letter two different travelling-wave, slot antenna arrays are proposed which can offer tunable switched-beam capability at millimeter-wave frequencies. The antenna systems are built ...

Waveguide Slot Array Antennas | SpringerLink Figure 15 shows the equivalent circuit of the array antenna with the traveling-wave excitation. The slot antennas are numbered from the end to the feed. The designed excitation amplitude of the n-th slot is given as a n. The normalized conductance to be determined of the n-th slot is g n. High-Gain Millimeter-Wave Planar Array Antennas with 3. Design of linear array with traveling-wave excitation. Both waveguide antenna and microstrip antenna are designed in common procedure based on the traveling-wave excitation. Reflection wave is neglected in the design since reflection-canceling post and slit are used for the waveguide antenna and the comb-line antenna, respectively.

Abstract: In this paper, a traveling wave slot array on substrate integrated waveguide (SIW) for 24GHz traffic monitoring is designed. The antenna array achieves beam steering through controlling the longitudinal slot spacing. The main beam points at an angle of 20° and has the advantage of miniaturization, easily fabricated and low cost.
