A Wideband Compact Planar Conical Loop Antenna
This paper reports the design of a wide band planar fed, planar conical loop Antenna. Parametric studies have been carried out to arrive at the optimum antenna dimensions to have a wide impedance bandwidth (VSWR<2). Experimental results confirmed the wide impedance bandwidth.
متن کاملSelection of Ideal Feed profile for Asymptotic Conical Dipole Fed Impulse Radiating Antenna
Abstract— Equivalent charge method is used to design ultra wide band asymptotic conical dipole (ACD) antenna. Combination of linear charge density and point charges is used to generate different profiles for ACD antennas. Two different profiles of ACD antenna are used as a feed for reflector based impulse-radiating antennas (IRAs). This paper focuses on the selection of ideal ACD profile as wel...
متن کاملA Compact and Low-Profile Tunable Loop Antenna Integrated With Inductors
We present a frequency-tunable, compact loop antenna which consists of a transmission line on a ground plane, two shorting posts, and two inductors which are serially connected between the posts and the edge of the transmission line. By properly choosing the inductance of the inductors, the operating frequency of the antenna can be controlled without seriously sacrificing fractional bandwidth. ...
متن کاملUHF RFID Antenna: Printed Dipole Antenna with a CPS Matching Circuit and Inductively Coupled Feed
This paper presents simulated (WIPL‐D pro) and measured results of a UHF RFID antenna realized with a dipole matched to a CPS (Coplanar Stripline) and inductively coupled with a small rectangular loop. Such a design enables achieving and controlling high values of the inductive reactance that is necessary for obtaining good match of the antenna to an Application Specif...
متن کاملLow-profile, Electrically Small Meander Antenna Using a Capacitive Feed Structure
The present paper describes a capacitive feed (C-feed) for small, low-profile linear antennas. A meander line, which is the radiating element, in such antennas with a metallic back conductor electromagnetically couples a metallic feed plate placed between the meander line and the back metal (ground). This antenna has a very small leakage current on the outer surface of the coaxial cable and can...
