英文摘要：
In this paper a novel Butler matrix based on Half-Mode Substrate Integrated Waveguide （HMSIW） technology is proposed and implemented. The prototype is fabricated at X-band （10GHz） with a standard double side PCB process. The measured insertion loss is 2dB; the size of the prototype is 24cm ×6.5cm. Compared with conventional microstrip technology, this structure has a lower insertion loss and better power handling capability. Compared with that based on SIW technology, the size of the Butler matrix is considerably reduced. Thus, it is a good candidate for beam-forming networks of microwave or millimeter wave muhi-beam antennas. The detailed design process and the measured results are presented.
