A Modular Shared-Aperture Circularly Polarized Phased Array Antenna at K/Ka-Band on LTCC. 2025 19th European Conference on Antennas and Propagation (EuCAP), 1–4. https://doi.org/10.23919/eucap63536.2025.10999557
Abstract:
A patent pending modular interleaved sharedaperture circularly polarized phased array antenna at K/Kaband is presented for satellite-on-the-move (SOTM) systems.
Based on a basic antenna array module with 8 Tx and 4 Rx
antenna elements, a larger antenna array can be easily
configured for higher gain. An antenna array with 128 Tx and
64 Rx elements on low temperature co-fired ceramic (LTCC) is
designed to cover frequencies of 17.7−21.2 GHz for downlink
(Rx) and 27.5-31.0 GHz for uplink (Tx) with boresight gain of
25 dBic (Tx) and 21 dBic (Rx), as well as beam steering range of
±45° with scan loss of 3 dB, respectively.
