提出了一种适用于60 GHz、具有一维波束控制能力的贴片天线阵。在该阵列中,移相器是基于液晶的曲折线,每一条都提供最大38°的差动相移。阵列单元(贴片天线)通过耦合间隙耦合到微带馈线。调整这些间隙,以便均匀地激励天线贴片。最终的设计包括一个4×1的贴片阵列,当液晶上的偏置从零变到饱和电压时,该贴片阵列能够在E面上扫描高达9°。
A patch antenna array with beam steering capability in one dimension for 60 GHz applications is presented. In this array the phase shifters are liquid crystal based meander lines, each providing a maximum differential phase shift of 38°. The array elements (the patch antennas) are coupled to the microstrip feed line through coupling gaps. These gaps are adjusted in order to uniformly excite the antenna patches. The final design comprises of a 4 × 1 patch array, which is able to scan up to 9° in the E-plane as the bias on the liquid crystal changes from zero to saturation voltage.
