The Circularly Polarized PCB Antenna is designed for OTA/RF testing of wireless terminals. It supports either left-hand circular polarization (LHCP) or right-hand circular polarization (RHCP) and covers a wide frequency range from 700 MHz to 7.5 GHz.
The antenna is available with either a cost-effective FR-4 substrate or a low-loss Rogers high-frequency laminate, making it suitable for circularly polarized RF signal transmission, reception, and performance verification in consumer electronics, wireless communication modules, GNSS terminals, and other RF applications.
✅ Wide Frequency Coverage
The 700 MHz–7.5 GHz operating range supports major wireless communication bands, including 4G/5G Sub-6 GHz, Wi-Fi 2.4 GHz / 5 GHz, and selected GNSS-related applications. A single antenna can support RF and OTA testing across multiple wireless standards.
✅ Optional LHCP / RHCP Configuration
The antenna can be configured for either left-hand circular polarization (LHCP) or right-hand circular polarization (RHCP), supporting different circularly polarized wireless systems.
Compared with linearly polarized antennas, circular polarization provides greater tolerance to DUT orientation and polarization angle, helping reduce polarization mismatch loss in relevant test applications.
✅ Two Substrate Options
FR-4 Version: A cost-effective solution for routine laboratory testing and production-line quality inspection.
Rogers Version: Features lower dielectric loss and improved high-frequency RF performance, making it suitable for applications requiring higher measurement accuracy and stability.
✅ Stable RF Matching Performance
With a VSWR of ≤ 2.1 across the specified operating range, the antenna provides stable impedance matching and repeatable RF performance for OTA measurements.
✅ Compact Flat-Panel Design
The antenna features a compact PCB structure with a thickness of 16 mm, making it easy to integrate with common RF/OTA chamber mounting fixtures and multi-antenna array configurations.
