“…Alternatively, the monopole principle has also been employed for the planar integrated structure based on complicated fabrication [4][5][6], but only narrow frequency bandwidth (Ͻ3%) was obtained. Differently, herein, a circular-patch antenna operating at TM 01 mode is proposed for on-body communication, and a sample is designed and simulated, and then tested both in free space and nearby an arm of human-body.…”

A very low‐profile conical antenna with a simple structure and wideband characteristic is proposed in this article. The antenna structure consists of a monoconical conducting body, a parasitic ring shorted to a finite‐sized ground plate to achieve low‐profile characteristic (Nakano et al., IEEE Trans Antennas Propag 56 (2008) 1187‐1192), and a sleeve attached to the ground for yielding an extreme wide VSWR bandwidth. The experimental result shows that the proposed antenna, with a height of only 0.0625 wavelength at the lower edge frequency of the bandwidth, exhibits a 7.9:1 impedance bandwidth from 747 to 5900 MHz with VSWR below 2.5. © 2009 Wiley Periodicals, Inc.

“…The conical antennas do not display any of such shortcomings, but their main challenge is their bulky structures. To miniaturize the structure and broaden the bandwidth, the conical antennas and their variations have been discussed [5,6]. Many efforts such as shown in Refs.…”

“…In fact, many problems of electromagnetic scattering on conical-like bodies have been solved. Some types of antennas based on biconical lines are proposed for transient electromagnetic waves radiating and receiving [1][2][3][4][5][6]. In order to improve or develop some biconical antenna it is necessary to understand the evolution of electromagnetic fields inside it.…”

Abstract-In the present paper a novel mathematical model of physical processes of transient electromagnetic waves excitation and propagation in a biconical transmission line with radially inhomogeneous magneto-dielectric filling is proposed. The model is based on time domain mode expansions over spherical waves. The basis functions of the mode expansions are calculated analytically. The mode expansion coefficients are governed by Klein-Gordon-Fock equation with coefficients depending on a radial spatial coordinate. The explicit finite difference time domain computational scheme is derived to calculate the mode expansion coefficients. Dependences of cutoff frequencies of higher modes of TE and TM waves on the line geometry and dielectric filling are studied. In order to calculate electromagnetic field in the line with higher accuracy, just finite number of terms in the mode expansions is required. Electromagnetic field excited by the transient electric ring current is calculated in both homogeneous and radially inhomogeneous biconical transmission line. It is shown that there is a possibility to increase the bandwidth of the line via introduction of partial dielectric filling without changing the line geometrical size.

“…Because of their electrically small size and essential broadband property conical antennas and their variations have been largely investigated for applications in broadband coverage [6][7][8][9][10][11][12][13][14]. Some of the antennas proposed in these papers have no low-profile characters and some of the antennas have no very broad band properties.…”

Abstract-A novel electric small conical antenna working on a very broad band, 0.47-6 GHz, with the height of only 60 mm, is presented. A capacitive ring on the top of the cone and three oblique shorted lines are used to expand the work band. By changing the width of the ring and the slope of the oblique line, the impedance of the antenna matches 50-ohm feed line commendably. Simulation and experiment results demonstrate that this antenna provides very broad band and low-profile characters, which exhibits a 12.8 : 1 impedance bandwidth with voltage standing wave ratio (VSWR) below 2 : 1 (the impedance bandwidth is 11.9 : 1 with the VSWR below 1.5 : 1) and with the height only 0.094 wavelength associated to the lowest frequency.
