摘要

采用可调谐超材料移相器设计了一种s波段波束可扫描4×4贴片阵列天线。移相器由一个串联可变电容和一个并联可调谐电感组成的4个MTM单元组成。电感由可变电容和四分之一波阻抗变压器实现。移相器的移相范围为280°(-87°~ 193°)，插入损耗为0.9 dB。天线10db带宽约为94 MHz，最大增益约为16 dBi。E面和h面波束扫描范围分别为43°和75°。

Beam scannable 4×4 patch array antenna using tunable metamaterial phase shifters

A beam scannable 4×4 patch array antenna using the tunable metamaterial (MTM) phase shifter has been designed at S-band. The phase shifter consists of four MTM unit cell composed of a series variable capacitor and a shunt tunable inductor. The inductor is realized by a variable capacitor and quarter wave impedance transformer. The phase shifting range of the phase shifter is 280° (from -87° to 193°) with the insertion loss of 0.9 dB. The 10 dB bandwidth and maximum gain of the antenna are about 94 MHz and 16 dBi, respectively. The beam scanning ranges in the E- and H-planes are 43° and 75°, respectively.
