Advantages of hybrid substrates in phased array antennas include:
High-frequency signal integrity: Combined with low-loss materials, it reduces loss and interference and improves signal integrity and reliability.
Design flexibility: Because of fine-pitch trace, the antenna element design is easier.
Thermal management: Reducing the packaging process is helpful for heat dissipation of high-power chips.
Size and weight benefits: Smaller and lighter, ideal for portable or space-constrained applications.
