Abstract :
In this work, the first mu-strip 60 GHz Rotman lens and new compact low loss strip delay line using low temperature co-fired ceramic(LTCC) are proposed. The lens has 3 steering capability for +26deg, -26deg, 0.1deg angle, - 0.86 dB of side lobe level (SLL), and 28deg of half power beam width (HPBW). The Rotman lens is designed in mu-strip structure for integration capability with the system on package (SoP). In order to replace bulky and lossy meander line of the Rotman lens, new compact low loss delay line is developed and verified. It shows remarkable performance; it has smaller insertion loss. Furthermore, It shows 78% of length reduction than meander line. Also, owing to its simple and symmetrical structure, the delay line is reciprocal and analogous.
