QuarterSense is a compact, high-performance communication unit engineered specifically for smart meter and industrial cabinet environments. Designed in an ultra-slim 0.5TE DIN-rail format, it integrates a wideband antenna directly into the device architecture, eliminating the need for external antennas while maintaining excellent RF performance — even inside dense metal enclosures.
The system supports Wireless M-Bus, NB-IoT, LTE-M, global LTE bands (including Sub-1 GHz), Wi-Fi, and ISM bands within a single integrated antenna structure. It can operate as a standalone smart meter communication module or as a gateway aggregating data from multiple meters and securely forwarding it to the cloud.
By merging antenna, mechanics, and electronics into one unified architecture, QuarterSense delivers reliable connectivity, maximum space efficiency, and true deployment flexibility — without compromise.

QuarterStar
NTN Antenna L-Band & S-Band
QuarterStar is a compact, high-efficiency dual-band antenna engineered for L- and S-band Non-Terrestrial Network (NTN) applications. Designed for reliable satellite connectivity in demanding environments, it delivers high gain and circular polarization performance within a robust and space-efficient form factor.
Covering 1.525–2.200 GHz and supporting NTN bands such as n255 and n256, QuarterStar provides up to 8 dBi peak gain with radiation efficiency above 80%. Its directional radiation pattern and RHCP/LHCP circular polarization ensure stable satellite links for maritime, aviation, industrial IoT, remote telemetry, and emergency communication systems.
With a compact Ø90 mm design, low-profile housing, and wide operating temperature range, QuarterStar integrates seamlessly into professional-grade devices without compromising performance. It is the ideal antenna solution for next-generation NTN connectivity where reliability, efficiency, and integration flexibility are essential.
At Quarterwave, we develop advanced antenna systems, integrated antenna modules, and smart sensing solutions built for high-end connectivity. Our products are designed for environments where performance is not optional — it is mission-critical.
From ultra-compact embedded antennas to fully integrated communication modules and intelligent sensor platforms, we combine electromagnetic expertise with system-level engineering. Instead of treating antennas as components, we design them as system-defining elements — optimized together with mechanics, electronics, and real-world installation conditions.
The result is reliable, wideband, and globally deployable connectivity across cellular, NTN, ISM, GNSS, and industrial communication standards. Whether for smart infrastructure, industrial IoT, mobility, energy, or precision agriculture — Quarterwave delivers solutions where physics, integration, and innovation work as one.

Aora
360° UWB AoA Antenna
The Aora is our advanced solution for 360° Angle of Arrival (AoA) detection in the UWB frequency range, representing one of the few antenna designs currently capable of enabling full spatial coverage in this domain. The antenna was originally developed for the dev kit platform of Qorvo QM35825, but is designed as a universal solution that can be integrated into a wide range of UWB systems.
The Aora concept combines three antennas into a single compact structure, enabling reliable 360° AoA measurement without mechanical repositioning or additional antenna arrays. This integrated multi-element design significantly simplifies system architecture while maintaining high angular resolution, robust signal reception, and scalable application potential across different positioning and sensing use cases.
