“…Therefore, in order to ensure the usefulness of the proposed antenna, the time domain response of antenna must also be examined. Based on the previous results, the proposed antenna is assumed to be excited by two wideband signals corresponding to UWB (3.1-10.6 GHz) and higher-band (11)(12)(13)(14)(15)(16)(17)(18).…”

“…The monopole metal plate antenna has a small width, 12 mm, placed over a small circular ground plane of radius 50 mm. These dimensions are smaller than those reported in the literature [6][7][8][9][10][11][12][13][14][15][16]. Two types of plate loading shapes, rectangular and cylindrical, are simulated via software package CST, and samples are fabricated and tested.…”

“…The requirements include a broad impedance bandwidth, omnidirectinal radiation patterns, constant gain and group delay, a stable transmit-receive transfer response and low pulse distortion, [1][2][3][4][5]. Among the many types of antennas that can provide wideband performance, the planar metal monopole antenna [8][9][10][11][12][13][14][15][16][17][18][19] exhibit excellent bandwidth as well as pattern performance. Broadband planar monopole (PM) antennas have found wide spread application in wireless communication services due to their attractive features like simple geometry, low profile, ease of fabrication, very low cost and omnidirectional pattern, but they usually show the directional radiation property at high operating frequencies due to their structural asymmetry.…”

Abstract-A novel, low profile and broadband plate loaded planar monopole antenna is investigated. The proposed antenna consists of a rectangular planar monopole with small plates attached to its radiating edges. Two types of plates, rectangular and cylindrical shapes are fabricated and tested. The characteristics of the antennas are investigated in both frequency and time domains. The study shows that the proposed antennas are capable of achieving broadband and omnidirectional radiation characteristics within 2.9-17.9 GHz with the cylindrical loading plates and 2.9-16.7 GHz for the rectangular loading plates with a gain of up to 7 dBi.

“…However, the size of the antenna is large, and the impedance cannot cover the whole band reported by FCC. To broaden the impedance bandwidth of the planar antennas, tapered slot technology [7,8] and wide slot antenna [9][10][11] have been studied and analyzed. But there are several existing narrow systems which have been used for a long time, such as HIPERLAN/2 bands (5.15-5.35 GHz and 5.470-5.725 GHz in Europe) and the IEEE 802.11a bands (5.15-5.35 GHz and 5.725-5.825 GHz in US) for wireless local area network communications.…”

Abstract-A coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna with a notch band characteristic is presented in the paper. The radiation patch of the proposed UWB antenna is designed using cantor set fractal technology. The bandwidth is broadened by setting two symmetrical triangular tapered corners at the bottom of the wide slot of the proposed UWB antenna. The notched band characteristic is achieved by employing a T-shaped tuning stub at the top of the wide slot. The notched band can be controlled by adjusting the length and the width of the T-shaped tuning stub to give tunable notched band function. The proposed cantor set fractal wide slot UWB antenna has been designed in details and optimized. Experimental and numerical results show that the proposed antenna, with compact size of 26 × 21 mm 2 , has an impedance bandwidth range from 2.8 GHz to 11 GHz for voltage standing-wave ratio (VSWR) less than 2, except the notch band frequency 5.0 GHz-6.3 GHz for HIPERLAN/2 and IEEE 802.11a (5.1 GHz-5.9 GHz).

“…Thanks to an intrinsic broad impedance bandwidth, planar monopoles show powerful features for those applications and different feeding techniques can easily be applied to this technology to obtain further benefits [1][2][3]. Low-profile antennas are particularly interesting for mobile or indoor applications, so that a compromise between size and performance becomes a crucial part of the design [4][5][6][7][8].…”

A novel folded monopole antenna is investigated numerically and experimentally. The proposed antenna comprises a short folded monopole suitably shaped at the base with two vertical grounding probes. This small antenna is shown to have a fractional impedance bandwidth up to 125% (1.6 GHz to 7.5 GHz) for a 10 dB return loss. An interesting compromise between impedance bandwidth and pattern control is found by tuning a double side bevel at the base of the monopole, the position of the feeding point and its distance from the ground plane. Measurements and simulations are in good agreement and show a dramatic improvement in terms of impedance bandwidth compared with planar and L-shaped monopole antennas. Impedance and radiation characteristics make this novel folded monopole antenna a remarkable candidate for indoor applications where the wideband coverage of different systems is required. The working bandwidth covers a large number of wireless communication systems including GSM 1800, Personal Communication System ( PCS1900), Universal Mobile Communications System (UMTS), the 2.4 GHz (2400-2484 MHz) and 5.2/5.8 GHz (5185-5350/5725-5875 MHz) bands for WLAN communication, GHz), the US-NII bands and the lower bands allocated to ultra-wideband communications.
