About
The piPATCH-S-DL is a Space-Friendly, highly radiation-efficient ZeroCore CubeSat S-band patch antenna working across the entire S-downlink band (2200-2290 MHz), intended for high-data-rate satellite communication systems. Unlike traditional laminated Rogers PCB-based antennas, it uses a ZeroCore permittivity layer with permittivity close to 1 (near-vacuum) and back-side EMI shielding, avoiding the near-field losses of dielectric-loaded designs and giving an excellent axial ratio. RHCP is achieved via a hybrid 0/90-degree phasing module implemented at the module level. S11 is better than -10 dB across the full band, with a peak response of -20 dB, and the antenna handles up to 10 W CW open-space input power. Measured RHCP mode gain is +4.7 dBd / +5.55 dBiC (front lobe), with gain flatness of +/-1 dB across the band and axial ratio better than 1 dB (+/-45 degrees). It is available in X/Y-mount (98×82.6 mm) or Z-mount (98×98 mm) versions with a 50-ohm MCX-Female right-angle connector (SMA-Female on request), rated over -40 to +85 degC. Offered as Flight Model (FM) and unmarked OEM Flight Model variants.
