摘要(中)

本論文以微型化之雙頻切換式波束成形模組為設計目標，首先，提出操作於1.8/5.8 GHz之微型化雙頻4 × 4巴特勒矩陣，設計上使用雙頻橋式T線圈取代傳輸線，同時達到微型化與雙頻化的效果，並可使於4 × 1天線陣列兩操作頻率下有相同指向效果。此1.8/5.8 GHz 4×4巴特勒矩陣實現於積體被動元件製程中，其晶片面積僅為10 mm × 5 mm，在5.8 GHz之電氣尺寸則為0.2λ0 × 0.1λ0。其次，為了搭配4 × 4巴特勒矩陣組成波束成型模組，本研究使用串-並聯電晶體及電阻，設計一DC-6 GHz吸收式單刀四擲開關，並實現於砷化鎵製程中，其晶片面積為1.5 mm × 1 mm，在5.8 GHz之電氣尺寸為0.029λ0 × 0.019λ0。

摘要(英)

In this study, a miniaturized dual-band switched beamforming module is proposed.First,a miniaturized 1.8/5.8 GHz 4 × 4 Butler matrix is presented,which is achieved by using dual-band bridged-T coils to replace the λ/4 lines for circuit size reduction and dual-band operation. In addition,when feeding a 4 × 1 linear antenna array ,it can achieve the same beam direction at the two operation frequencys.The proposed dual-band Butler matrix is implemented in a integrated passive device process,and the chip size is only 10 mm × 5 mm,which corresponds to an electrical size of 0.1λ0 × 0.2λ0 at 5.8 GHz.Second,a DC-6 GHz absorptive SPQT switch is realized,which is designed using a series-shunt configuration and resistors.It is implemented in a GaAs pHEMT process,and the chip size is 1.5 mm × 1 mm,while the electrical size is 0.029λ0 × 0.01λ0 at 5.8 GHz.It can be used with the proposed 4 × 4 Butler matrix to form a compact dual-band switched beamforming model.
