Description
TC-93160A Spiral Antenna Coupler Overview
The TC-93160A Spiral Antenna Coupler is designed for reliable wireless device testing up to 12 GHz. Engineers commonly use this antenna coupler for near-field testing while accurately simulating far-field conditions. Because of its performance and flexibility, the TC-93160A Spiral Antenna Coupler is well suited for validating complete wireless device assemblies, including integrated antennas.
This antenna coupler uses Right Hand Circular Polarization (RHCP), which makes it ideal for testing GPS, GNSS, and other circularly polarized wireless devices. RHCP polarization helps reduce interference and improves signal consistency during radiated testing inside RF shield boxes and Faraday cages.
Spiral Antenna Coupler for Near-Field and Far-Field Simulation
The TC-93160A Spiral Antenna Coupler combines the compact benefits of standard inductive couplers with the added advantage of increased placement distance from the device under test (DUT). This spacing allows engineers to test the entire wireless device assembly instead of only the antenna feed point.
As a result, the coupler delivers improved repeatability when testing in a near-field environment while simulating far-field behavior. This makes it especially useful for applications that demand consistent and repeatable RF measurements.
For installation, mount the antenna coupler using a fixture and secure it to the ceiling of the Faraday cage. This configuration provides optimal signal coupling and stable test conditions.
RHCP Technology for Reduced Multipath Interference
RHCP antennas, or Right Hand Circular Polarized antennas, differ from LHCP (Left Hand Circular Polarized) antennas in how they interact with reflected signals. Circular polarization helps reduce radio interference caused by multipathing, which occurs when signals reflect off surfaces inside a test enclosure.
By minimizing multipath effects, the TC-93160A Spiral Antenna Coupler delivers a cleaner RF signal. This improved signal quality supports more accurate radiated testing within RF shield boxes, also known as Faraday cages.
Ideal for GPS and GNSS Testing Applications
The TC-93160A Spiral Antenna Coupler performs well in GPS and GNSS testing environments. Its RHCP design aligns with satellite-based communication systems, making it a strong choice for navigation and location-based device validation.
For applications focused exclusively on GPS testing, engineers may also consider complementary antenna coupler options designed specifically for those use cases.
