Reception Characteristics of Monopole Antennas for Electron Plasma Waves

Creating Band-Notched Characteristics for Compact UWB Monopole Antennas

In 2002, the FCC in the US authorized the unlicensed use of the ultrawideband (UWB) frequency spectrum for commercial applications in the range from 3.1 to 10.6 GHz with an emission limit of -41.3 dBm/MHz which is near to the thermal noise floor [1]. UWB communication systems operating in such a wide frequency band and low power emission level could easily be interfered by the existing nearby c...

Monopole Antennas

This article describes the concepts underlying monopole antennas and their many applications, such as for broadcasting, car radios, and more recently for cellular telephones. In its simplest form, the monopole antenna above an infinite ground plane shown in Fig. 1(a) can be considered as one-half of a corresponding double-length center-fed linear dipole shown for comparison in Fig. 1(b). The cu...

Broadband Planar Monopole Antennas

Monopole antennas have several advantages but for their narrow bandwidth. Broadband planar monopole antennas have all the advantages of the monopole in terms of their cost, and ease of fabrication besides, yielding very large bandwidths. For many applications large bandwidth is required. Recently, many techniques to tailor and optimize the impedance BW of these antennas have been investigated. ...

Printed Monopole Antennas for Multiband Applications

In this paper, we have investigated printed rectangular monopole antennas, which is basically a printed microstrip antenna with etched ground plane for multi-band applications. In particular, we have fabricated and tested printed rectangular monopole antennas for dual-band and penta-band applications. It has been observed that printed rectangular monopole antennas are small in size and simple i...
