Design a single section, quarter wave impedance transformer at 6 GHz from 4.75 cm $$\times$$ 2 cm guide to 3.75 cm $$\times$$ 1 em guide. Assume air filled wave guide with transformersection having same width as that of the input and output sections,

A

Height = 1.414 cm, Length = 3 cm

B

Height = 1.6 cm, Length = 2.5 cm

C

Height = 1.414 cm, Length = 2.5 cm

D

Height = 1.5 cm, Length = 3. cm
