en.Wedoany.com Reported - On June 4, US millimeter-wave test equipment provider MilliBox announced that it will showcase multiple millimeter-wave and sub-terahertz testing innovations and live demonstrations at the IEEE MTT-S International Microwave Symposium IMS 2026, held from June 7 to 12 in Boston, USA. During the exhibition, MilliBox will display compact benchtop anechoic chambers, antenna positioners, OTA test systems, and radar testing solutions at booth #13075.
One of the key new products featured at this event is the Fast Synchronized Trigger (FST) function for the GIM04 and GIM05 modular positioner series. This function enables real-time synchronization between the antenna positioner and most vector network analyzers, allowing the test system to acquire data during motion rather than repeatedly following the traditional "move, stop, acquire" process. For millimeter-wave antenna, radar module, phased array, and in-vehicle sensor testing, 3D radiation pattern acquisition is often time-consuming, especially in high-resolution scanning and multi-frequency test scenarios, where test efficiency directly impacts the pace of R&D iteration. The significance of FST lies in more tightly integrating mechanical positioning, trigger signals, and VNA acquisition processes, thereby reducing OTA test time while maintaining data consistency under high-precision measurement requirements.
In live demonstrations, MilliBox will use the MBX32CTR compact range antenna test system, paired with the GIM04F-300EV positioner featuring FST, Copper Mountain Technologies' new BFx-02 frequency extension base, and Virginia Diodes' new VNAX TxRx WR-10 frequency extender, to showcase 3D OTA rapid acquisition capabilities in the 75GHz to 110GHz frequency band. This band covers the critical W-band range, targeting applications such as high-frequency radar, early-stage 6G research, satellite communications, advanced sensing, and millimeter-wave device verification, all of which impose stringent requirements on the test system's dynamic synchronization capability, anechoic chamber environment, frequency extension link, and positioning accuracy.
MilliBox will also present a radar testing solution based on the MBX32R compact benchtop anechoic chamber. This system introduces fixed targets, moving targets, and simulated targets into the test environment, combining the WLL09 instrumented wall, GIM04H-300X three-axis antenna positioner, trihedral corner reflectors, and Eravant's 77GHz radar target simulator to demonstrate radar performance testing, characteristic tuning, and modular testing capabilities in millimeter-wave and sub-terahertz scenarios. As automotive radar, industrial radar, unmanned system sensors, and smart device perception modules continue to evolve toward higher frequency bands and more complex waveforms, laboratory test systems need to simulate a greater variety of real-world target states within limited spaces. The combined value of benchtop anechoic chambers and modular positioners is on the rise.
Another highlight is the broadband configuration of the MBX02K antenna test system. MilliBox will use the Anritsu ME7838 VectorStar vector network analyzer, covering a frequency range of 14GHz to 110GHz, to measure Eravant's dual-ridge antenna. This demonstration will showcase the system's ability to acquire 97 3D radiation patterns in a single scan, covering a 97GHz spectral range. For R&D teams and university laboratories, broadband single-scan testing capability reduces the time costs associated with band switching, repeated calibration, and multi-equipment setup, making millimeter-wave antenna, ultra-wideband device, and high-frequency system verification more compact and efficient.
MilliBox's product positioning has consistently emphasized low-barrier, modular, and benchtop millimeter-wave testing. Traditional millimeter-wave OTA testing often relies on large anechoic chambers and expensive systems, with high deployment costs, space requirements, and scheduling expenses. By offering small benchtop chambers, combinable positioners, and open-source control software, MilliBox aims to enable more R&D teams to perform antenna pattern, OTA metrics, radar debugging, and high-frequency link verification within their daily laboratories. The FST, radar test system, and broadband antenna test solutions showcased at IMS 2026 further reinforce its product roadmap in "miniaturized high-frequency test infrastructure." As demand for 5G millimeter-wave, 6G research, automotive radar, satellite communications, sub-terahertz devices, and high-frequency material testing grows, such equipment will more directly serve early-stage R&D validation, small-batch trial production, and rapid engineering iteration.
MilliBox will also showcase a jointly developed cost-effective compact range antenna test system at the Cornes RF Engineering booth. This system employs a lens-based near-field to far-field transformation structure, paired with the MBX02KC anechoic chamber and GIM06 antenna positioner, designed for the Ka-band and V-band. Virginia Diodes will also present a new VNAX TxRx M2 form factor solution suitable for integration with MilliBox's three-axis antenna positioner at its booth. This cross-vendor combination indicates that millimeter-wave testing is transitioning from single-instrument procurement to a coordinated configuration of "anechoic chamber, positioner, frequency extender, VNA, software, and target simulator." For companies in communications, radar, and high-frequency devices, the ability to quickly build a repeatable, scalable, and automated test environment will directly impact the speed at which products move from prototype validation to engineering finalization.
