A dual resonant antenna configuration is developed for multistandard multifunction mobile handsets and portable computers. Only two wideband resonant antennas can cover most of the LTE spectrums in portable communication equipment. The bandwidth that can be covered by each antenna exceeds 70% without using any matching or tuning circuits, with efficiencies that reach 80%. Thus, a dual configuration of them is capable of covering up to 39 LTE (4G) bands besides the existing 2G and 3G bands. 2 × 2 MIMO configurations have been also developed for the two wideband antennas with a maximum isolation and a minimum correlation coefficient between the primary and the diversity antennas.

A distributed multiple-input multiple-output chaotic radar based on wavelength-division multiplexing technology (WDM) is proposed and demonstrated. The wideband quasi-orthogonal chaotic signals genera...
Implanted antennas for implant-to-air data communications must be composed of material compatible with biological tissues. We design single and dual-polarization antennas for wireless ultra-wideband n...
Radar based Microwave Imaging (MWI) has been widely studied for breast cancer detection in recent times. Sensing dielectric property differences of tissues has been studied over a wide frequency band ...

Conventional mirrors obey the simple reflection law that a plane wave is reflected as a plane wave, at the same angle. To engineer spatial distributions of fields reflected from a mirror, one can eith...
The investigators will conduct a randomized placebo-controlled trial of a computerized intervention targeting cognition in 30 teens with autism spectrum disorder.
This is a research study because it is commonly observed that sleep in its quantity and quality is influenced by the type of mattress used at night. A recent study in patients with back pa...
The purpose of the study is to collect phenotypic (observable characteristics) and genetic information about individuals with Autism Spectrum Disorders (ASDs) and their families.
Autism spectrum disorder (ASD) has been given a high priority for genetic and neurobiological study. There is no such information in Asian population and no study has conducted using Diffu...
The purpose of the present study was to determine whether teaching Karate techniques training leads to reduction in communication deficit of children with autism spectrum disorders.
Health insurance providing benefits to cover or partly cover hospital expenses.
A broad-spectrum spectrum antineoplastic antibiotic isolated from Streptomyces refuineus var. thermotolerans. It has low toxicity, some activity against Trichomonas and Endamoeba, and inhibits RNA and DNA synthesis. It binds irreversibly to DNA.
