JEM Engineering

JEM Engineering has years of experience designing antennas for both military & commercial applications from HF to millimeter wave. JEM can design and develop antennas to meet your specific requirements. Areas of Antenna expertise include: Active Genetic Aperture Low-Observable Broadband Microstrip Patch & Arrays Electrically-Small Wire JEM manufactures its own antenna designs and offers build-to-print manufacturing capabilities?all to ISO 9001 standards of quality (Mil spec and FAA quality systems also available). JEM?s manufacturing expertise utilizes a combination of both in-house and outsourced fabrication methods and assembly. Antenna Testing: Capabilities include: antenna voltage standing wave ratio (VSWR), gain, radiation pattern and coupling/isolation testing. Offering production testing services, chamber rental (with operator) by the hour, half-day or full day. Tapered Chamber: This 14? x 14? x 45? tapered anechoic chamber provides far-field testing from 100 MHz to 40 GHz. Satimo Chamber: This Satimo STARGATE-64 spherical near-field range is the fastest antenna measurement facility available today for full-sphere data collection. This system has the capability to measure radiation patterns, gain and antenna efficiency in either free-space conditions or with surrogate or live human test subjects. Both passive and active antenna measurements can be performed for a wide variety of devices operating between 400 MHz and 6 GHz. Data output options include full 3D and conventional 2D radiation patterns. ASCII data files are easily processed using such tools as MATLAB®, MathCAD® or EXCEL®. By utilizing this state-of-the-art testing facility companies can cut costs and save time by completing measurements in minutes?measurements that would take hours with a conventional range.
