Souderton, PA -- AR RF/Microwave Instrumentation has redesigned its AT5080 log periodic antenna to extend its frequency coverage. The new model AT6080 extends from 80 MHz to 6 GHz for radiated EMC testing. The broad frequency range addresses existing RF susceptibility requirements as well as anticipated future developments. The frequency range is also matched to work directly with AR "W and "S" Series RF power amplifiers.

The newest member of AR's family of log periodic antennas that feature the company's "bent element" approach, the AT6080 is suitable for use in both traditional applications and new compact chambers. The proprietary "bent element" design provides a size reduction of approximately 60% compared to traditional log periodics without sacrificing key electrical performance such as gain and bandwidth. The size reduction minimizes field loss that results from "room loading." This is a considerable problem when conventional log periodics are used in small enclosures.

The design can accommodate the high power levels necessary to generate E-fields. The AT6080 can also be calibrated for RF emissions testing. Tough enough for outdoor use, the AT6080 features removable elements for ease of transportation.
