piPATCH-S-UL/FM (Flight Model)

Space-Friendly™ S-Band Uplink Antenna.

The piPATCH-S-UL is a World's First Space-Friendly Highly Radiation Efficient ZeroCore CubeSat Patch Antenna working in the whole S-Uplink Band (2025-2110 MHz) intended for High Data Rate satellite communication systems. S11 parameter is set to -10dB at least over the whole range, with peak of -20dB response. The RHCP (Right Hand Circular Polarization) is achieved using hybrid 0/90° phasing module implemented on the module level.

Industrial Advantage. | Better Link Margin.

What is different? Unlike traditional laminated Rogers PCB-based antennas, the piPATCH-S-UL contains the ZeroCore permitivity layer and EMI shielding from the back side.

Third party antennas typically use dielectric materials with permittivity greater than 3.5 to shrink the size and tweak the radiation pattern. The piPATCH-S-UL antenna is working with permittivity very close to 1, which is almost an ideal case for a vacuum-based dielectrics. Centered on the groundplane also makes it ideal with radiation pattern and polarization. The excellent axial ratio makes it a Number One on the Market.

Lower Noise Pickup. | Perfect Gain. |  Better RSSI.

Struggle no more with affecting the old-fashioned microstrip Wilkinson dividers-based Antennas backs interacting with your satellite harness and internals. They can freely pickup noise from the satellite bus, decreasing the Signal-to-Noise Ratio of the S-band uplink receivers. 

Use Shielded piPATCH-S Series Antennas for your Communication systems instead. And! Get Your Data Up!

Available in X/Y or Z mount.

Yes. Same as the piPATCH-S-DL Downlink S-Band Patch Antenna, the piPATCH-S-UL Uplink S-Band Patch antenna is available in X/Y and Z side mounts.
