LPDA

A log periodic dipole array (LPDA) is a wideband antenna with moderate gain which can be used for monitoring and jamming applications. Its broad frequency coverage reduces the number of antennas required in an electronic warfare (EW) system.

The LPDA’s in our range cover the spectrum from 2 MHz to 6 GHz. High-power versions are offered for jamming purposes, lower power versions for monitoring applications. Hybrid LPDA-Dipole designs provide compact antennas which still perform at low frequencies.

The typical 6 to 10 dBi gain of an LPDA gives it a beamwidth of 30° to 60°, ideal for directional jamming and monitoring.

An LPDA is an efficient frequency-independent antenna, and offers true wideband performances without any loading. Wideband, omni-directional antennas are often loaded with resistors to improve their bandwidth, this is at the expense of total radiated power. An LPDA is an array of driven elements of different lengths, where not all elements in the array are active at a single frequency. An LPDA can be operated over a range of frequencies having a ratio of 2:1 or higher. Over this range, its electrical characteristics – gain, VSWR, front-to-back ratio etc. remain more or less constant.
