A compact dual port UWB-MIMO/diversity antenna for indoor application

Author: Sonika Priyadarsini Biswal, Sushrut Das

A compact printed quadrant shaped monopole antenna is introduced in this paper as a good prospect for ultra wideband- multiple-input multiple-output (UWB-MIMO) system. The proposed MIMO antenna comprises two perpendicularly oriented monopoles to employ polarization diversity. An open circuit folded stub is extended from the ground plane of each radiating element to enhance the impedance bandwidth

A novel design of Scarecrow-shaped patch antenna for broadband applications

Author: Bhupendra Kumar Shukla, Nitesh Kashyap, Rajendra Kumar Baghel

A novel Scarecrow-shaped patch antenna has been presented for broadband applications. The proposed antenna composed of an elliptical shape radiating patch, partial ground plane, and 50 ? microstrip line which is Boolean added with the radiating patch. To achieve wide impedance bandwidth, an elliptical notch and two rectangular-shaped parasitic slots have incorporated on the ground plane. This ante

A novel miniaturized log-periodic dipole array antenna using dynamic scaling factor for RFID application

Author: Pourya Rostami Gooran, Gholamreza Karimi, Ali Lalbakhsh

A novel radio frequency identification antenna based on log-periodic dipole array (LPDA) antenna at 5.8 GHz is presented. The antenna design approach consists of two major steps. Firstly, the conventional primitive method is used to design a traditional LPDA antenna. The antenna structure is then miniaturized and its overall performance significantly improved. Dynamic scaling factor along with uni

Quasi-self-complementary ultra-wideband antenna with band rejection characteristics

Author: Rajarshi Sanyal, Partha Pratim Sarkar, Santosh Kumar Chowdhury

This article presents a compact novel quasi-self-complementary semi-octagonal-shaped antenna for ultra-wideband (UWB) application. The proposed novel structure is fed by a microstrip line where different rectangular truncation is etched to the ground plane as an impedance matching element, which results for much wider impedance bandwidth (VSWR<2) from 2.9 to 20 GHz. In order to obtain band-notched

Broadband circularly polarized slot antenna arrays using linked elliptical slots for - and -band applications

Author: Saeed Mohammadi-Asl, Javad Nourinia, Changiz Ghobadi, Maryam Majidzadeh

Compact broadband circularly polarized elliptical slot antenna arrays (CPESAAs) are devised based on 2 × 2 and 4 × 4 circularly polarized (CP) elliptical slot antennas and a sequential phase feed network. To realize the circular polarization, eight rectangular stubs are embedded in the feed structure to excite two orthogonal E vectors in 2 × 2 CPESAA configuration. Moreover, by taking four rectang

Completely integrated multilayered weave electro-textile antenna for wearable applications

Author: Esther F. Sundarsingh, Malathi Kanagasabai, Vimal Samsingh Ramalingam

This paper proposes a unique, first of its kind fabrication technique for the making of textile antennas. A novel method that provides scope for automation in textile antenna production is presented here. A completely integrated textile antenna fabrication method that eliminates the tasks of positioning and fastening of the various components of a patch antenna is discussed. The technique employs

Fractal antenna arrays for MIMO radar applications

Author: Christoph Dahl, Michael Vogt, Ilona Rolfes

In this contribution, fractal antenna arrays are analyzed for their applicability in multiple-input multiple-output (MIMO) radars. Array geometries based on the Fudgeflake fractal and the Gosper island fractal are investigated. In addition, a concept for the combination of both fractals is shown in order to increase the flexibility concerning the number of transmitting and receiving antennas. The

Two-dimensional scattering of a Gaussian beam by a homogeneous gyrotropic circular cylinder

Author: Shi-Chun Mao, Zhen-Sen Wu, Zhaohui Zhang, Jiansen Gao

Two-dimensional scattering of a Gaussian beam by a homogeneous gyrotropic circular cylinder is presented. The incident Gaussian beam source is expanded as an approximate expression with Taylor's series. The transmitted field in the homogeneous gyrotropic cylinder is expressed in terms of the series of wave functions based on the integral equation. The unknown coefficients of the scattered fields a
