Rotman Lens Antenna in Microstrip Configuration

Design of Rotman Lens Antenna at Ku-Band Based on Substrate Integrated Technology

In this research work, a multibeam antenna which is a combination of a beamformer network (BFN) and a linear array antenna, has been designed. A Rotman lens has been chosen as beamformer network and Vivaldi antennas have been selected for constructing array antenna. The Substrate Integrated Waveguide (SIW) was used for implementing Rotman lens. After explanation the structure of Substrate integ...

Design and Implementation of a Single Feed Dual Band Microstrip Patch Antenna For GPS Applications

Abstract: The purpose of this paper was to design and implementation a single feed, dual frequency ( L1, L2) patch antenna for the Global Positioning System (GPS). The results from the simulation and measurement for this antenna is presented, compared, and used as part of the validation process for the dual frequency, right hand circularly polarized patch antenna designed for GPS L1, L2 operati...

Design and Performance Analysis of MIMO-DSSS System for 2.4 GHz ISM Band Wi-Fi Applications Using Microstrip Antennas

In this paper, compact antenna has been designed and implemented in a 2X2 Multiple-Input Multiple-Output (MIMO) system. The antennas are compact double-sided printed microstrip patch antennas and fed by a microstrip line designed for a frequency of 2.4 GHz used for industrial, scientific and medical (ISM) band applications. Polarization diversity of the two antennas is used to construct indepen...

A Modified E-Shaped Microstrip Antenna for Ultra Wideband and ISM band applications

In this paper, the analysis of a modified E-shaped patch antenna is presented. The purpose of the modification over the original Eshaped structure is to accommodate the operating frequency band and signal bandwidth requirements of the Ultra Wideband (UWB) wireless system. Simulation results show that the modified E-shaped has fulfilled the frequency band and signal bandwidth requirements of the...
