A wide Bandwidth Pyramidal Horn Antenna with Enhanced Gain Using Metasurface layer
A new design of a pyramidal horn antenna operating at 8-18 GHz based on the waveguide structure is presented in this paper. A metasurface layer, which consists of a set of periodic unit cells, is employed on the E-plane walls of the horn antenna ...

The eleven antenna: a compact low-profile decade bandwidth dual polarized feed for reflector antennas [PDF]
A novel dual polarized ultrawide-band (UWB) feed with a decade bandwidth is presented for use in both single and dual reflector antennas. The feed has nearly constant beam width and 11 dBi directivity over at least a decade bandwidth.

Monitoring insulator contamination level under dry condition with a microwave reflectometer [PDF]
—Build-up of surface contamination on high voltage insulators can lead to an increase in leakage current and partial discharge, which may eventually develop into flashover. Conventional contamination level monitoring systems based on leakage current,

A Compact Vivaldi Shaped Partially Dielectric Loaded TEM Horn Antenna for UWB Communication
Ultrawideband (UWB) antennas are of huge demand and Vivaldi antennas as well as the TEM horn antennas are good candidates for UWB applications as they both have relatively simple geometry and high gain over a wide bandwidth.

The effects of PO43- removal from aqueous solution with varied concentrations of metal oxides in steel slag filter system [PDF]
High amount of orthophosphate will accelerate the growth of autotrophs and eutrophication will occur. This phenomenon decreases the water quality and as a result may increase the cost of water treatment for drinking water.
