High-efficiency wideband transmit-array antenna with linear polarization in Q-band
A new linearly-polarized discrete lens antenna for satellite applications is designed in 42-
GHZ band with 1-bit phase quantization and attractive unit cell design. A three-layer
structure is adopted for the phased array to achieve design simplicity. The unit cell is
characterized by using Gaussian optics measurements. The design and optimization of the
power budget has been theoretically analyzed and verified experimentally. The unit cell's
impedance matching measurements show a reflection loss below− 10 dB at 40.3–42.6 GHz …
