Slow-wave antennas
Leaky-wave antenna (LWA) belong to the more general class of traveling wave antenna, that use a traveling wave on a guiding structure as the main radiating mechanism. Traveling-wave antenna fall into two general categories, slow-wave antennas and fast-wave antennas, which are usually referred to as … Visa mer The traveling wave on a Leaky-Wave Antenna is a fast wave, with a phase velocity greater than the speed of light. This type of wave radiates continuously along its length, and hence the propagation … Visa mer Groove guide (shown in Fig. 5) is a low-loss open waveguide for millimeter waves, somewhat similar to the NRD guide: the dielectric central region is replaced by an air region of larger width (greater than λ0/2). The field again decays exponentially in the regions of … Visa mer A typical example of a uniform leaky-wave antenna is an air-filled rectangular waveguide with a longitudinal slot. This simple structure illustrates the basic properties common … Visa mer In response to requirements at millimeter wavelengths, the new antennas were generally based on lower-loss open waveguides. One … Visa mer An interesting variation of the previous structures has been developed and analyzed.
