Investigation and Comparison Between Radiation Center and Phase Center for Canonical Antennas

Design and Development of High Gain, Low Profile and Circularly Polarized Cavity-backed Slot Antennas Using High-order Modes of Square Shaped Substrtae Integrated Waveguide Resonator

In In this paper, two low profile, single fed cavity backed slot antennas providing a circularly polarized (CP) wave are introduced. One of the antennas presents a right-handed CP (RHCP) wave, while the other one offers a left handed CP (LHCP) wave. The proposed antennas consist of a square shaped Substrtae Integrated Waveguide (SIW) cavity incorporatng two couples of radiating slots to radiate...

Coupling Effects and Performance of Loran Transmitter Antennas

It is known that if a conductor resides in the neighboring of an antenna with a small distance relative to the wavelength, it induces a reverse current on the conductor. This paper involves the unavoidable coupling effects on some common types of LF antennas, due to the large wavelength in this frequency band. In particular, after some discussions about top-loaded antennas, the coupling effect ...

An Algorithm to Calculate Phase-Center Offset of Aperture Antennas when Measuring 2-Dimensional Radiation Patterns

Phased array antenna using MEMS phase shifter

This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...

Cabazitaxel antiproliferative mechanism of action in U87MG human glioblastoma cells: a promising cell-cycle phase-specific radiosensitizer

Introduction: One mechanism of cell cycle manipulation and mitotic catastrophe is arrest at G2/M phase of cell cycle. Cabazitaxel, a mitotic inhibitor agent, is a second-generation semisynthetic taxane. An expected anti-neoplastic effect of Cabazitaxel is cell cycle perturbation and alteration of microtubule dynamics. In contrast to other taxane compounds, Cabazitaxel is a poo...
