Single-feed multibeam conformal transmitarrays using a superposition method are presented in this letter. The arrays consist of ultrathin Huygens elements with independent amplitude and phase manipulations. Three cylindrical conformal transmitarrays with dual-beam radiation patterns are designed at 10 GHz, producing dual beams at ±30°, +30°, and −20°, +30° and −10°, respectively. As an experimental validation, the prototype with symmetrical dual beams is fabricated and measured. Two beams at +29° and −28° along the H-plane are achieved with a measured 18.29 dBi peak gain. The gain difference between the two beams is 0.13 dB. Good agreement between simulation and measurement is observed.

具有相位和幅度调制的单馈多波束共形发射阵列

这封信中介绍了使用叠加方法的单馈多波束保形发射阵列。该阵列由具有独立幅度和相位操作的超薄惠更斯元件组成。三个具有双波束辐射模式的圆柱共形发射阵列设计在 10 GHz，分别产生 ±30°、+30° 和 -20°、+30° 和 -10° 的双波束。作为实验验证，制造并测量了具有对称双光束的原型。沿H平面在 +29° 和 -28° 处的两个波束实现了测得的 18.29 dBi 峰值增益。两个波束之间的增益差为 0.13 dB。观察到模拟和测量之间的良好一致性。
