Active Loop Antenna
AL-130R
-
Also known as Magnetic Loop Antenna, the AL-130R is compliant with CISPR 16-1-4. It is ideal for emissions measurements as required by various EMC standards such as FCC 18, CISPR 11, CISPR 13, CISPR 14, CISPR 32 and many more. The built-in, low-noise preamplifier, increases overall measurement sensitivity as well as the overall signal to noise ratio. As per ANSI C63.4-2014, the use of active loop antenna for compliance testing is permitted in a non-sheilded environment ONLY if the saturation indicator is continuously monitored during the course of testing. Com-Power’s Remote Antenna Interface (RAI-100) comes in very handy for this application. It is a compact controller which can be used to enable/ disable RF measurement circuit and monitor saturation and battery low conditions remotely via a fiber optic cable up to 30 mtrs in length.

The AWA-0142 is an active array for 5G wireless applications developed using planar antenna technology resulting in a very low profile, lightweight unit. The surface mount assembled antenna board is based on Anokiwave’s AWMF-0135 Silicon Quad Core IC and demonstrates the performance achievable using low power silicon integration and efficient antenna layout and design. Using the AWMF-0135, the antenna provides +60dBmi (1000 W) of EIRP. The electronic 2D beam steering is achieved using analog RF beam forming, with independent phase and gain control in both Tx and Rx operating modes. The AWA-0142 antenna leads the way in showing how 5G coverage can be rolled out by network operators using the mmW bands, with low power footprint and high energy efficiency, while meeting key operating specifications for data rate, latency, coverage, and reliability.
