This paper presents the use of PN junction diode on fractal monopole antenna with microstrip line for rreconfigurable multiband antennas. The developed multiband antennas focus on the applications for Wi-Fi, cordless telephone and satellite & radar. A fractal reconfigurable antenna was designed using the known fractal geometry such as Sierpinski gasket is fed by strip line using coaxial feed. A...

This paper describes the design, realization and experimental measurements of an antenna element to operate at ultra-wideband (UWB) spectrum. The type of this antenna is a circular disk monopole (CDM), with two notches opposite to each other at two sides of the disk. The feed of the antenna is a coplanar waveguide (CPW). The effect of the presence of the notches is studied through simulations a...

Attempt is made to modify the radiation pattern of a patch antenna using a meta-structure consisting of an array of monopole antennas in the near field. The effect of the metastructure on the radiation characteristics of the patch antenna, for different angular arrangements of the metastructure plates, has been experimentally studied.

381 Abstract— A monopole triangular shaped, broadband, compact microstrip patch antenna with shorting pin is presented in this paper. By defecting the ground plane bandwidth of 38.7% with respect to center frequency of a Microstrip patch antenna has been achieved which can be used for WLAN application. 82.4% size reduction has also been achieved by using shorting pin of a microstrip patch anten...

A novel compact, dual layer UWB monopole antenna is presented. This low profile ultrawideband antenna is fed by a 50 Ω shielded strip-line with an array of metal vias making the conducting walls. A printed disc monopole with a circular cut is the radiating element. The dual layer, shielded strip line feed allows for integration in multilayer technologies. The ultra-wideband, monopole characteri...

In this manuscript, a novel design of ultra-wideband (UWB) monopole antenna with dual frequency band-stop performance is proposed. The proposed antenna consists of an ordinary square radiating patch with a pair of rotated T-shaped slits, and a modified ground plane with an inverted Ω-shaped and a pair of rectangular-ring slots. In the presented structure, by cutting a pair of rectangularring sl...

In this paper, we present a compact and low-profile monopole antenna with a simple structure for the 2.6-2.73 GHz frequency band, the Worldwide Interoperability for Microwave Access (WiMAX) and the Wireless Local Area Network (WLAN) applications. The first configuration of our antenna mainly consists by three radiating elements: inverted L-shaped Stub1, L-shaped Stub2 and a rectangle Stub3. By ...

Folded monopole antennas have been used for many years in medium frequency amplitude modulation broadcast applications. These antennas offer a grounded radiating structure with a height approximating a quarter wavelength. Folded monopoles have been studied exhaustively during a recent effort in an attempt to characterize the input impedance and directivity characteristics as a function of monop...

INTRODUCTION: By modifying the monopole antenna array (MA) for whole brain imaging, we developed extended and shielded monopole antenna array (ESMA) in order to enhance the uniformity of imaging at 7T MRI application. We compared the performance of this new coil with two different types of coils, namely, MA and extended monopole antenna array (EMA). The three coil types were evaluated for the t...
