Log-Periodic EMC Antennas

30 MHz–5 GHz

Applications

  • Radiated Emissions
  • Radiated Immunity
  • Pre-Scan/Full Compliance

Features

SunAR RF Motion antennas feature an innovative design philosophy that makes them the practical choice for EMC testing. New manufacturing techniques that simplify assembly and minimize the use of hardware, create an electrically stable measuring instrument that stays in calibration and holds up to the environment.

SunAR RF Motion log-periodic antenna booms are made from a custom aluminum extrusion that reduces the number of parts at the front of the antenna, resulting in a stronger, more stable feedpoint. The unique shape allows for a larger feed cable to be used, which significantly increases the maximum power rating. Dipole elements are permanently attached to the boom by a construction technique that maintains excellent electrical characteristics for the life of the antenna. A tough powdercoat finish with UV inhibitors seals the aluminum structure and protects it from sunlight and moisture.

Includes individual A2LA accredited calibration.

MOUNTING

All SunAR RF Motion antennas have a 22 mm diameter stainless steel rear mounting tube. This configuration enables polarization changes without physical displacement of the antenna, and minimizes the effect of the RF cable by keeping it well behind the antenna elements. The SunAR RF Motion SNAP! mount provides a secure interface to most antenna positioning towers. It locks the antenna in place, prevents unwanted rotation and facilitates rapid antenna changes.

LP60

Directional Antennas

400 MHz–6 GHz

Applications

  • EMC and wireless testing
  • Site survey
  • In situ testing

Features

Our low-profile directional antennas are designed for EMC and wireless testing applications from 400 MHz to 6 GHz and beyond. These antennas are etched on a low-loss microwave substrate. The broadband, log-periodic structure enables operation over a very wide frequency range with constant gain. Innovative design and manufacturing techniques result in long-lasting performance.

A stainless steel rear mounting tube aids in mounting and handling. An optional Polarization Mount (pictured) is available for use with a tripod or permanent fixture. Kits available.

LP80, LP100

Directional Antennas

80 MHz–3 GHz
100 MHz–3 GHz

Applications

  • EMC Radiated Emissions
  • EMC Radiated Immunity
  • Signal monitoring and detection

Features

Model LP80 & LP100 are directional antennas designed for transmitting and receiving RF signals from 80 or 100MHz to 3GHz. The broadband characteristics of the log-periodic structure enable it to operate with a nearly constant gain and radiation pattern over the entire frequency range.

Innovative design and manufacturing techniques result in long-lasting strength and performance. The antenna boom is made from a custom aluminum extrusion that reduces the number of mechanical RF junctions. Dipole elements are attached to the boom by a technique that maintains excellent electrical characteristics for the life of the antenna. A tough powdercoat finish with UV inhibitors seals the aluminum structure and protects it from sunlight and moisture.

The LP80 & LP100 have a rear tube that allows polarization adjustments without changing antenna height. This also minimizes the effect of the RF cable by keeping it well behind the antenna elements. The SNAP! mount provides a secure interface to antenna positioning towers. It locks the antenna in place and prevents unwanted rotation during polarization changes.

PD Series

Precision Dipole Antennas

450 MHz–3 GHz

Applications

  • Signal Injection
  • EMC and Wireless Testing
  • Signal monitoring and detection

Features

Our PD Series Precision Dipoles are narrowband, resonant antennas that are designed for transmitting and receiving RF signals at specific frequencies. They are manufactured in accordance with ANSI/AAMI PC69:2000.

Each dipole is one-half wavelength long at its frequency of operation and contains a series-parallel coaxial stub balun that meets rigid specifications. Dipoles cut to custom frequencies are available upon request.

An optional polarization mount is available for use with a tripod or permanent fixture.
