Modified design of obtaining dual-circular polarization radiation of a single-feed square microstrip antenna are proposed and experimentally studied. The proposed single-feed dual circular polarized design is achieved by inserting four Tshaped slits at the patch edges of a square microstrip antenna. Details of the design considerations of the proposed antenna are described, and experimental res...

The superhydrophobic surface is widely used to reduce friction for the flow inside micro-channel and can be used to control/manipulate fluid, cells and even proteins in lab-on-chip. Fabricating micro grooves on hydrophobic surfaces is a common method to obtain such superhydrophobic surface. This study utilized the numerical method to investigate the effect of eccentric micro-grooves on the fric...

The paper is focused on the micro-channel in LTCC (Low Temperature Co-fired Ceramics), which is one of the methods used for the creation of a fluid sensor. The sensor is composed of a mechanical and electrical part. The mechanical part is 3D structure, where are particular layers lamination on itself. There are many shapes, which creation results micro-channel after lamination and sintering. Th...

A micro-channel heat sink is a promising cooling method for high power integrated circuits (IC). However, the understanding of such a micro-channel device is not sufficient, because the tools for studying it are very limited. The details inside the micro-channels are not readily available. In this letter, a micro-channel heat sink is comprehensively studied using the integrated temperature sens...

Increasing the power and reliability of microelectronic components requires heat sinks with greater transport performance. This study investigates hydraulic performance a silicon sink under constant flux 100 W/cm2 liquid coolant running through parallel microchannels. The coupled transfer walls coolant, modelled as single-phase fluid, is examined over Reynolds number range 100?Re?350 for micro-...

Objective: In this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. Methods: The base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. Lorentz electric force, which is used as stimulating flow factor, is created by appl...

In broadband DS-CDMA uplink transmission using frequency-domain equalization (FDE) without cyclic prefix (CP) insertion, the transmission performance degrades due to inter block interference (IBI) and circular property loss. The schemes were proposed to solve the problems of IBI and circular property loss in our previous study with the assumption of perfect channel estimation. In this paper, th...
