Modified sierpinski monopole antenna for UWB applications with multibands

01 Jun 2017-pp 1143-1147
TL;DR: In this article, a modified Sierpinski fractal antenna with a ring structure for UWB applications is presented. But the proposed antenna developed two bands with the resonant frequencies of 4.76 GHz and 8.6 GHz with a return loss of −51db and −58.37db respectively.
Abstract: This thesis reports the modified design of Sierpinski fractal antenna with a ring structure for UWB applications. The fractal system is a method to miniaturize the antenna dimension to enhance its radiation and broadband properties. Due to the self-similarity property possessed by the fractal structure it has the multiband behavior. The proposed modified antenna with ring structure operates in the frequency range of 4.06 GHz to 9.13 GHz. The introduction of ring structure improves the bandwidth of the antenna. The proposed antenna developed two bands with the resonant frequencies of 4.76 GHz and 8.6 GHz. The each band operates with a return loss of −51db and −58.37db respectively. The design and performance analysis of the proposed antenna was done with CST Microwave Studio software.

TL;DR: In this paper, a multiband sierpinski fractal patch antenna for the X and Ku-band applications is presented, which is designed and fabricated using Rogers RT/Duroid 6202 (lossy) substrate with a dielectric constant of 2.94 and a height of 1.52mm.
Abstract: This paper presents a multiband sierpinski fractal patch antenna for the X and Ku-Band applications. This antenna is designed and fabricated using Rogers RT/Duroid 6202 (lossy) substrate with a dielectric constant of 2.94 and a height of 1.52mm. The zero, first and second iteration of the antenna for multiple frequency band of radiation for a frequency band of 8-18 GHz with simulated and practical results is discussed here.

TL;DR: Fractal antennas as mentioned in this paper can be applied to antenna elements to obtain high performance, resonant antennas for many practical applications, such as hand-held transceivers and wireless devices.
Abstract: Applying fractals to antenna elements allows for smaller, resonant antennas which are multiband/broadband and may be optimized for gain. They do not use additional loading components and are simple and cost-effective to fabricate. They can be mounted to constraining form factors, such as the casing of hand-held transceivers. Fractal antennas prove worthwhile, high performance, resonant antennas for many practical applications. Usually fabricated as or on small circuit boards, they allow new versatility in their use with wireless devices.

Abstract: A small, wideband microstrip-fed monopole antenna for mobile communication systems, is designed. The antenna has a wide bandwidth ranging from 1.65 to 10.6 GHz for S11<−10 dB. Various mobile communication services such as DCS, WCDMA, UMTS, WiBro, WLAN, DMB and UWB can easily be covered by the proposed antenna simultaneously. Details of the antenna design and measured results are presented and discussed.

TL;DR: In this article, the effect of the partial ground plane removal in different configurations on the radiation characteristics of a microstrip antenna was investigated numerically, and a new soft-surface configuration consisting of an array of stand-up split ring resonators (SRRs) were placed on a bare dielectric substrate near the two ground plane edges.
Abstract: This study presents a new, simple method for reducing the back-lobe radiation of a microstrip antenna (MSA) by a partially removed ground plane of the antenna. The effect of the partial ground plane removal in different configurations on the radiation characteristics of a MSA are investigated numerically. The partial ground plane removal reduces the backlobe radiation of the MSA by suppressing the surface wave diffraction from the edges of the antenna ground plane. For further improving the front-to-back (F/B) ratio of the MSA, a new soft-surface configuration consisting of an array of stand-up split ring resonators (SRRs) are placed on a bare dielectric substrate near the two ground plane edges. Compared to the F/B ratio of a conventional MSA with a full ground plane of the same size, an improved F/B ratio of 9.7 dB has been achieved experimentally for our proposed MSA.
