LOG PERIODIC
DIPOLE ARRAYS
LPA series antennas are log periodic dipole arrays comprising of two or more log periodic dipole
antenna elements. All
LPAs are designed for medium to high gain and high cross-polar rejection.
These antennas are ideally suited for generating high fields required for immunity testing.
Two-element log periodic dipole arrays, such as the
LPA-8200, LPA-2201, and LPA-2020, offer
flat gain over a large bandwidth and low VSWR similar to the performance of an ordinary log
periodic dipole antenna. This is extremely useful in generating maximum field strength uniformly
over a large test area. A two-element array has 2 to 3 dB higher gain relative to an ordinary log
periodic dipole antenna. All two element arrays are optimized for identical beamwidths in both E
and H-planes
.
The
LPA-2020/A3 is supplied with a 7/16 connector to handle high input power levels in excess of
3 kW.
