A novel miniature antenna based on the fractal Hilbert geometry is presented. The antenna becomes electrically smaller as the fractal iteration increases at a higher rate than that of any other fractal geometry presented until now. Several fractal-shaped Hilbert monopoles have been constructed, measured, and compared with the classical /4 monopole. © 2003 Wiley Periodicals, Inc. Microwave Opt T...

In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes a beam forming smart antenna. An experimental model in UHF...

This paper gives information about construction of planar rectangular monopole antenna on Printed Circuit Board (PCB). Behaviour of such planar antenna is same as the rectangular patch antenna with finite ground plane which lies in same plane of given PCB. The designed antenna is a broadband antenna as its ratio bandwidth falls under broadband category. In comparison with monopole antenna broad...

A planer monopole ultra wideband (UWB) antenna with single and dual band notched characteristics are presented in this article. Proposed antenna consists of simple rectangular shaped patch with sequential notches which is inserted in two lower corners. In order to obtain band notched properties ‘U’ shaped conductor backed plane (CBP) is embedded. Multiple ‘U’ shaped CBP can realize multiple fre...

A two-port antenna with high isolation for digital television system (DTV), global system for mobile communication (GSM), and universal mobile telecommunications system (UMTS) indoor applications is presented. The antenna consists of a disk loaded sleeve monopole antenna and an inverted-L plate antenna, which are combined into one radiation structure. In addition, by using a choke tube and C-sh...

In this letter, a simple monopole antenna with variable band-notched characteristic for ultra wide band (UWB) function is proposed. Two L-shaped quarter-waveguide resonators coupled to the ground plane with two shorting tracks at the sides of the antenna are used to generate stop-band performance around 5.5 GHz (WLAN). The proposed antenna is fabricated on the substrate FR4 (relative permittivi...

This paper tells how to construct rectangular monopole antenna which will be printed on printed circuit board (PCB). The antenna behaves as planar monopole antenna as it has rectangular patch and ground plane which lies in same plane of PCB. Also this antenna is a broadband antenna because its ratio bandwidth lies under broadband category. In comparison with monopole antenna broadband planer mo...
