Embodiment Construction
[0040] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0041] The small S-band passive phased array antenna with high radiation efficiency proposed in this paper is the antenna used for the transmitter of relay measurement and control. The design of the antenna conforms to miniaturization and high maturity. Design complexity and weight of passive phased array antenna systems.
[0042] The invention provides a small S-band passive phased array antenna with high radiation efficiency, such as figure 1 As shown, including: power supply module, power amplifier module, filter module, beam control module, phase shifter module and antenna array;
[0043] The power module provides power for the power amplifier module, beam control module and phase shifter module. The power amplifier module amplifies the input S-band RF signal, and then sends it to the filter module for filtering to suppress out-of...
