An active hybrid shared-aperture concept (employing both active and passive circuits) is presented. This active shared aperture realizes the required isolation level of 48 dB between transmit (30 GHz) and receive (20 GHz) channels of a ground termina

This paper presents a millimeter-wave tunable hybrid-transformer-based duplexer concept with dual-antenna configuration. By using orthogonal sequentially-rotated linearly-polarized antennas and the hybrid-transformer-based duplexer, the transmitter a

The problem of beam squinting in circularly polarized offset reflector antennas is solved by using a novel focal-plane array concept that consists of sequentially rotated linearly polarized elements. This concept can be used to facilitate beam steeri

This paper presents a novel technique to accurately measure the RF voltage across the tuner in order to ease the design procedure of aperture tuned antennas. The presented approach can be used together with MEMS based variable digital capacitors with

It is shown that metal gratings can be used to improve the cross polarization of circularly-polarized aperture-coupled microstrip antennas. The metal gratings reduce edge difiraction from the flnite- size grounded dielectric slab on which the antenna

Despite the common belief that multiple sclerosis (MS) is a painless disease, several studies contradict this. There are a significant number of MS patients who actually suffer from painful conditions such as central and peripheral neuropathy, migrai

Among the ethnic groups, the age-standardized incidence rate of colorectal cancer (CRC) is highest among African-Americans. The majority of CRC arise from preexisting adenoma. It is shown that 30% of the US adult population has adenomas. The potentia
