A Reconfigurable Radial Line Slot Array Antenna for WiMAX Application

Adaptive Antenna Array for Satellite Communication Systems

Satellite Communication Systems are beneficial in providing communication services to vast regions especially where the adequate infrastructure for communication may not be constructed. Wireless communication is one of the fastest growing fields in the engineering world. Introduction on adaptive antenna array is described in this paper. Linear adaptive algorithm LMS (Least mean square) is used ...

Slot-line antenna array for high field parallel transmit MRI

Objective Parallel transmission is receiving more and more attention in MRI, and multi-element transmit MRI systems become commercially available. A number of different Tx/Rx antenna types have been presented for usage in parallel transmit configurations: degenerate birdcage coils, decoupled TEM or stripline coils [1,2,3]. All of these ‘traditional’ coil-types have their pro’s and con’s. We pro...

High Gain Broadband Plasmonic Slot Nano-Antenna

High gain broadband plasmonic slot nano-antenna has been considered. The theory of plasmonic slot nano-antenna (PSNA) has been developed. The analytical model takes into account also the electrical field inside the metal due to imperfectness of metal in optical range, as well as numerical investigation based on finite element method (FEM) has been realized. It should be mentioned that Yagi-Uda ...

A Satellite On-Board Radial Line Slot Antenna with Honeycomb Structure

A radial line slot antenna with honeycomb structure for satellite on-board equipment is proposed in this paper. The slot coupling with three-layer dielectric waveguide is analyzed by the method of moments and is incorporated into the design method of the radial line slot antennas. The first model with the diameter of 900mm is fabricated; the gain is 33.9dBi with efficiency of 35.5% and the refl...
