Integration of Circular Polarized Array and LNA in LTCC as a 60-GHz Active Receiving Antenna Academic Article uri icon


  • A compact 60-GHz active receiving antenna array is designed and fabricated using low temperature co-fired ceramic (LTCC) technology. It integrates a 4$, imes,$4 circularly polarized (CP) patch array and a 21-dB low noise amplifier (LNA) into the same package substrate. By applying a stripline sequential rotation feeding scheme the CP array exhibits a wide impedance bandwidth $({
    m SWR}< 2)$ and 3-dB axial ratio bandwidth, both over 8 GHz, as well as a beam-shaped pattern with a 3-dB beam width of 20$^{circ}$ and a peak gain of 16.8 dBi. By applying a bond wire compensation scheme and low-loss transition optimization, the LNA is successfully integrated into the package. The final fabricated prototype measures only 13$, imes,$20$, imes,$1.4 mm$^{3}$, demonstrates the good integration performance as well as the CP polarization characteristics in measurement, and is estimated to have a peak overall gain of at least 35 dBi.
