This paper presents the latest advances in extending semiadditive process (SAP) methods to 2–5 μm lines and spaces, achieved using dry film photoresists on thin glass substrates, toward meeting the routing requirements for 20-μm bump pitch interposers. High-density chip-to-chip interconnections on 2.5-D interposers are a key enabler to meet the high logic to memory bandwidth needs of next-gener...

The high frequency conductivity of thin metallic and graphitic nano-films attracts interest due to many potential applications in spin electronics, electromagnetic shielding, flexible antennas, displays, and in solar cells. Surface morphology of thin conducting nano-films typically consists of an isolated clustering structure, which can evolve into a conducting percolated network [1]. The high ...

Recently, spiral inductors have widely been used in the design of matching circuits of a wireless transceiver. However, such elements usually have low quality factor (Q) and may encounter the self-resonance in microwave-frequency band which permits its use in higher frequencies, and on the other hand, they occupy the large on-chip space. This paper presents a new design theory for the impedance...

A compact series-fed, omnidirectional printed dipole array for millimeter-wave (mm-wave) bands n257, n259, and n261 is proposed. series feed technique with microstrip to grounded-co-planar waveguide (CPW) transition was used the antenna. The prototype fabricated measured range from 27.25 28.5 GHz. peak gain 10.3 dBi a maximum azimuthal ripple of 4.4 dB.

A simple scheme for the realization of terahertz (THz) fundamental-mode tunable closed-stopband composite right/left-handed leaky-wave antennas (CRLH LWAs) is presented. The proposed CRLH LWAs are reconstructed by graphene-based coplanar waveguide (CPW) transmission line supercells. Their shunt inductances achieved narrow graphene strips two unit cell structures halved. designed and confirmed n...

The Chugach-Prince William (CPW) terrane is an Upper Cretaceous to Eocene accretionary complex exposed for ~2200 km in southern Alaska, extending from Baranof Island in the east to Sanak Island in the west. One of the thickest subduction-related accretionary complexes in the world, the CPW terrane is composed of deep-water flysch and associated volcanic rocks and is intruded by near-trench plut...

This paper presents a design of triangular wide slot antenna with same shaped patch which is fed by CPW. Patch is working as a radiating element and wide slot working as a ground. Detail simulation is conducted to understand its behaviour and optimize for broad band operation. The results are analysed and discussed in terms of return loss, VSWR, Gain, current distribution etc. The result shows ...

A printed monopole antenna with CPW-fed is proposed. The proposed antenna includes a rectangle shape radiator, two ground planes with symmetrical notch and feed excitation. It covers the all ultra wideband (UWB 3.1GHz ~ 10.6GHz) and has 7.8GHz (2.8GHz ~ 10.6GHz) measured return loss bandwidth. In modifiable design, we choose to design the notches on the ground plane, the high of the proposed an...

In this paper, angular displacement and angular velocity sensors based on coplanar waveguide (CPW) transmission lines and S-shaped split ring resonators (S-SRRs) are presented. The sensor consists of two parts, namely a CPW and an S-SRR, both lying on parallel planes. By this means, line-to-resonator magnetic coupling arises, the coupling level being dependent on the line-to-resonator relative ...

An Antenna is a metallic structure that transmits and receives radio waves. Antennas come in all shapes sizes from tiny microstrip antenna for biomedical applications to very big parabolic reflector antennas satellite communications. A Super Wideband Square Monopole designed on Arlon AD260A FR4 Epoxy with CPW-feed structure. Notched bands are obtained by embedding inverted E-shaped stub, using ...
