The AH-118 is a broadband, linearly polarised Double Ridge Waveguide Horn Antenna, operating over the frequency range of 700 MHz to 18 GHz; and with excellent efficiency between 1 GHz and 18 GHz. It can be used as a receiving or transmitting antenna.

Construction

The AH-118 is a broadband, linearly polarised Double Ridge Waveguide Horn Antenna, operating over the frequency range of 700 MHz to 18 GHz; and with excellent efficiency between 1 GHz and 18 GHz. It can be used as a receiving or transmitting antenna.

Application

The AH-118 Double Ridge Horn Antenna is suitable for use as an EMI test antenna for qualification level regulatory compliance measurements (FCC, CE, MIL-STD-461, RTCA DO-160, FDA, SAE, etc.).

The AH-118 is equally suitable for use transmitting antenna for establishing radiated RF fields for product immunity tests, and is capable of handling power levels up to 300 Watts. Another common application for the AH-118 is to use it as a “substitution antenna” for determining the Effective Radiated Power (ERP) and/or Effective Isotropic Radiated Power (EIRP) of intentional radiators (RF transmitters). These tests are typically applicable for products operating within licensed frequency bands requiring FCC/TCB Certification, and also for European acceptance tests per ETSI standards for radio equipment.

Notwithstanding the above applications, the AH118 can also be used for site comparisons, shielding effectiveness tests of enclosures, field monitoring, site surveys and other general purposes.
