8.14 - 8.17 GHz 18 dBi
SINGLE PANEL
Skewed-beam arrays have their main beam located at an angle to the normal to the array aperture. The resulting antenna is polarized in a plane orthogonal to the beam tilt.
Transmission-type polarizers are available to rotate the polarization to another plane - (see page 113).
Beam tilt from normal can range from about 3 to 65 degrees. Beam tilt changes with frequency in these arrays; this may limit the usable bandwidth for some applications. Arrays of this type are also used in frequency-scanning radars where this effect is used to advantage.
These arrays are quite thin and can be combined together to form larger panel arrays for higher gains, utilizing external waveguide power combiners.
MULTIPLE PANELS
Airborne radar applications find this type of antenna to be highly efficient. The mechanical structure is very rigid and thin. It is ideal for low swept-volume applications.
This design is limited, however, by the beam-broadening effects from the beam tilt of each array. First sidelobe levels of 25 dB, a gain of 31.5 dBi, azimuth beamwidth of 3.3°, elevation beamwidth of 8.0° with a weight of 7.2 pounds has been achieved for a 30-inch wide array.
