Ultra-Wideband Printed LPA Antenna

The optimized printed Log-Periodic Dipole Array Antenna (LDPA) is designed for RF testing and signal monitoring, providing reliable ultra-wide frequency coverage from 400MHz to 8GHz. This antenna is perfect for radio testing and field measurement scenarios.

Key Features:

• Stable RF Performance: Rated 50Ω input impedance ensures compatibility with standard RF equipment, delivering consistent performance across bands. Achieves return loss of approx. 10dB or less with a VSWR of around 2 in most bands above 1GHz. In the 400MHz–1GHz band, return loss is about 4.5dB or less with a VSWR of around 4.
• Handheld Radio Direction Finding: Supports general-purpose radio direction finding from 1GHz to 8.5GHz. Easily locate signal sources by rotating your body and the antenna to observe changes in signal strength.
• Optimized for tinySA ULTRA Spectrum Analyzer: Designed to pair seamlessly with the tinySA ULTRA spectrum analyzer, transforming your portable test device into a complete mobile RF measurement and direction finding kit. Features a direct plug-and-play connection.
• Compact Form Factor with Balanced Design: Achieves wideband performance in a compact 27×23cm footprint, prioritizing low-frequency matching and directionality while maintaining portability.

Packing List:

The package includes one ZA-048 Log-Periodic Dipole Array Antenna set. Please note that the TinySA Ultra+ and SMA cables are for demonstration purposes only and are not included. The adjustable mounting bracket is compatible with 2.8-inch TinySA and 4-inch TinySA Ultra+ models (ZS405 / ZS406 / ZS407), enabling professional RF signal direction finding setups.
