“…The thrust of developing gigabit wireless communication systems has provoke the use of license‐free spectrum around 60 GHz from 57 to 66 GHz. This range of frequency is suitable for short‐distance radar and indoor wireless communications because of high oxygen attenuation losses (10‐15 dB/km) at 60 GHz . A planar transmission line is a basic component of microwave/millimeter‐wave integrated circuits used in wireless communication systems.…”

“…Several configurations of micromachined microstrip line are reported at millimeter‐wave frequencies. It is introduced in silicon where the line is suspended on a single and multilayer thin dielectric membranes like polyimide, Si 3 N 4 . While in References and , the line is shielded with another micromachined air‐dielectric cover from top, benefits from low dispersion and dielectric loss, known as shielded‐membrane microstrip.…”

The effect of finite-size recessed ground on characteristic features of a microstrip transmission line is investigated and verified experimentally on alumina substrate of height 0.127 mm with ε r = 9.8 at 60 GHz. A measured characteristic impedance of 238 Ω, effective dielectric constant of 3.09, and attenuation constant of 3.4 Np/m is achieved by using a recessed ground of dimensions (width × depth) 4.5 mm × 0.95 mm, below a 50-Ω (on conventional ground plane) microstrip line.The effect of recessed ground on lumped equivalent circuit elements of microstrip line discontinuities including series-gap, open-end, and step discontinuities is also studied. To show the usefulness of recessed ground microstrip line, a prototype of fifth-order Chebyshev-type recessed ground end-coupled band-pass filter is designed and fabricated at 60 GHz. The filter exhibits measured insertion loss lower than 2.2 dB and return loss better than 13 dB over 3-dB passband of 6% centered at 60 GHz. The measured results show good consistency with simulated results and confirm the usefulness of recessed ground plane microstrip line. K E Y W O R D S
