“…A monopole is a common antenna capable of producing omnidirectional conical beams, whose performance can be improved by changing the shape or characteristics of the ground plane. For example, ground planes in modified solid or in defected shape [8][9][10][11] are used to realize multiple resonances; the electrical bandgap (EBG) [12], fractal or quasi-fractal [ 13,14] and band-notch structures [15] can also be used in the ground plane for bandwidth enhancement, resonance flexibility and miniaturization.…”

Abstract-A new C-band monopole antenna is proposed for use in a CAPS-based vehicle monitoring system. This monopole antenna has highly omnidirectional main beam with low elevation angle and sufficient half-power beamwidth by using a cone-shaped ground plane. The impedance bandwidth defined by 10 dB return loss is 650 MHz (5.50-6.15 GHz), and the main beam elevation angle and halfpower beamwidth are about 20 • and 44 • at the operating frequency 5.885 GHz, respectively. The manufactured prototype has survived a long-distance terrestrial test across China, and the design requirements for the satellite link budget, volume, cost, etc. have been reached.

“…The bandwidth increment would be achieved at some cost, but it can benefit the users by providing a higher data rate with shorter download time. The various feed structures that can be used for bandwidth enhancement, resonance-mode realization, and size reduction of a monopole antenna include the probe [11][12][13][14], the microstrip [15][16][17], and the coplanar waveguide (CPW) [18][19][20].…”

This paper presents a unique and miniaturized dual-band coplanar waveguide (CPW-fed) antenna for modern wireless communication. A new technique of using a modified ground structure (MGS) and frequency shifting strips (FSS) has been employed in the design to achieve dual-frequency operation. The proposed antenna generates two separate impedance bandwidths and covers the minimum required frequency bands of GSM 1800, GSM 1900, and WiFi/WLAN 5 GHz. The proposed antenna is relatively small (17 × 20 mm 2 ) and operates over frequency ranges 1.51~2.06 and 4.43~6.70 GHz. The designed antenna was simulated using Ansoft HFSS, a FEM based simulator, and antenna characteristics, such as reflection coefficient, gain, radiation efficiency, radiation pattern, impedance bandwidth, VSWR, surface current, and electric field distributions, are reported in this paper. The effect of the antenna's key structural parameters on its performance is also analyzed.
