In this paper, a coplanar waveguide (CPW)-fed dual-band slot antenna with circular polarization (CP) is presented. In order to achieve CP characteristic, an asymmetric slot and F-shaped end patch are introduced to a conventional rectangular slot antenna. Moreover, by cutting a T-shaped notch on the ground plane, the axial ratio (AR) bandwidth (ARBW) can be extended. The antenna shows left-hand ...

The main focus of this paper is to study and analyze how the performance of rectangular U slot antenna is affected by the parameters like Feed point position. The work presented herein is a simulation based study. Experimentally, it has been revealed that variations in parameters such as the width and length of the U-slot, height and size of the patch, probe size and location as well as substra...

A simple, compact, slot loaded stacked wideband microstrip patch antenna is presented in this communication. The radiating element consists of a rectangular patch with a Tshaped slot and is fed by a 50 Ω microstrip line. The proposed antenna is simulated using IE3D software, 12.32 version of Zeland. The simulated results show that the antenna can exhibit wideband characteristics. The impedance ...

Abstract—A probe-fed, slotted rectangular patch antenna has been proposed. Bandwidth enhancement has been achieved by suitably cutting slots into the rectangular patch, and efficiently exciting the slot by short circuiting the conducting patch through the dielectric substrate beyond the edge of the slot. Proposed antenna is suitable for various ground based and airborne applications in C-Band. ...

In this paper, a dual frequency resonance antenna is analysed by introducing L-shaped slot in a semi circular patch, different parametric studies have allows and the results in terms of return loss and radiation pattern are given. It is observed that various antenna parameters are obtained as a function of frequency for different value of slot length and width; it is easy to adjust the upper an...

In recent years, the introduction of new indoor communication wireless protocols such as Bluetooth, IEEE 802.11b, and wireless local area networks (WLANs) has led to enormous challenges with respect to antenna designs for wireless communications. The newer WLANs, however, have to provide high-speed wireless connectivity between PCs, laptops, and other equipment in corporate, public, and home en...

In the present paper a three U-shaped slot loaded disk patch antenna is analysed by using circuit theory concept. The antenna shows dual resonance. The resonance frequency of single layer patch is found to be 1.84 GHz and 2.61 GHz (simulated 1.80 GHz and 2.61 GHz) whereas for two layers dielectric antenna, it is 2.21 GHz and 3.14 GHz (simulated 2.20 GHz and 3.13GHz) respectively. The frequency ...

A novel multiband multiple-input-multiple-output (MIMO) antenna system is proposed. The MIMO antenna system consists of two antenna elements, each of which comprises of three radiators: a driven monopole, an S-shaped strip and an inverted F-shaped strip and occupies footprint of 15x18.5x0.8 mm3 only. The driven monopole acts as a quarter-wave monopole and stimulate higher mode resonance. The tw...

This paper presents a frequency reconfigurable inverted circular patch antenna with Uslot. The incorporation of U-slot in the circular patch provides a wide impedance bandwidth than conventional patch antenna. By introducing shorts at appropriate position on U-slot and on feed, antenna can be made resonant at two frequency bands (1.80GHz-1.98GHz) and (2.10GHz-2.68GHz) in two modes. The proposed...

A method is presented which is aimed at increasing bandwidth of the tapered slot antenna by just finding the optimum tapering profile of the antenna without the need to increase its size rather than decrease. In this paper, an ultra-wideband (UWB) antenna with a compact size of 16 mm x 20 mm is proposed for USB dongle applications. Theproposed antenna has been designed on FR4 substrate dielectr...
