Ku Band 15-17G 256elements Phased Array Antenna for Radar System

ZD-PAA-KUR-15/17G

This surface-mount Ka-band subarray operates in the 15–17 GHz range and supports single-beam, time-division duplex transmission and reception in pulse mode, with a maximum duty cycle of 25% and pulse width of 50 µs. The 16×16 array (256 elements) features independent phase shift and attenuation control per channel, including single-channel switching capability, and provides overvoltage, overcurrent, and timing-disorder protection to prevent burnout. It reports on-chip TR component temperature during operation and includes a low-power mode that powers the RF control chip while disabling the RF channel signal. Vertically polarized by design, the subarray measures 10 mm × 10 mm and supports scanning ranges of –45° to +45° in both azimuth and elevation. Key performance specifications include EIRP ≥77 dBm (15.5–16.5 GHz) and ≥74 dBm (15–17 GHz), G/T ≥ –1.5 dB/K and ≥ –4.5 dB/K over the respective bands, sidelobe suppression >27.5 dB, axial ratio ≤3.5 dB at ±45° scan (16 GHz), beamwidth (normal) of 5.91°±0.6° in transmit and 7.2°±0.8° in receive, and beam pointing accuracy ≤0.2°.

This Ku-band phased array antenna operates in the 15–17 GHz frequency range, supporting single-beam, time-division duplex transmission and reception in pulse mode with a maximum duty cycle of 25% and pulse width of 50 μs.This ku antenna is a array antenna for radar system It adopts an advanced surface-mount architecture with vertical polarization, integrating 256 tightly arranged radiating elements in a 16×16 orientation and pitch configuration within a compact 10 mm × 10 mm form factor. Each channel features independently programmable phase shift and attenuation, enabling flexible beamforming and single-channel on/off control, while built-in overvoltage, overcurrent, and timing disorder protection ensure robust and fail-safe operation even under abnormal control sequences.
Equipped with intelligent beam control and telemetry capabilities, the antenna reports real-time operating temperature of the TR components and supports a low-power standby mode that keeps the RF control chip powered while disabling the RF signal path. Its beam scanning coverage reaches ±45° in both azimuth and elevation, delivering consistent pattern performance across wide angles. At broadside, typical beamwidth is 5.91°±0.6° for transmission and 7.2°±0.8° for reception, with pointing accuracy better than 0.2°.
Designed for high-performance satellite communication and radar applications, the subarray delivers EIRP of ≥77 dBm (15.5–16.5 GHz) and ≥74 dBm (full band), G/T of ≥–1.5 dB/K and ≥–4.5 dB/K over the respective ranges, sidelobe suppression greater than 27.5 dB, and axial ratio ≤3.5 dB at ±45° scan. With its high integration density, lightweight surface-mount packaging, and comprehensive environmental protection features, this subarray provides a scalable, high-reliability building block for radar antenna system
