A Modular Shared-Aperture Circularly Polarized Phased Array Antenna at K/Ka-Band on LTCC
A patent pending modular interleaved shared-aperture circularly polarized phased array antenna at K/Ka-band 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 (L TCC) 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.
