In this letter, a technique for enhancement of bandwidth along with gain is proposed here. This article deals with design, modeling and simulation of slotted antenna. A star shaped parasitic patch is introduced in the centre of antenna to improve the gain along with the bandwidth by exciting additional resonances. For enhancing bandwidth, a slotted approach is used in ground of antenna along wi...

In this paper, the bandwidth of rectangular Microstrip antenna is enhanced by ‘I’ slotted rectangular microstrip patch antenna. In some applications which the increased bandwidth is needed, proposed antenna is one of the alternative solutions. The proposed antenna has been designed at the 2 GHz frequency. The frequency band of proposed antenna is in between (1.64-3.26 GHz) the fractional bandwi...

A probe feed, slotted hexagonal patch antenna has been proposed. Bandwidth enhancement has been improved by suitably cutting slots into hexagonal patch. Proposed antenna is suitable for various telecoms, LAN, WiFi applications in ISM-band. It is demonstrated that the proposed antenna exhibits resonance in ISM-Band and a peak gain of 6dBi.The antenna structure is described and simulated results ...

The Design of hexagonal patch is presented withsingle coaxial feed namelysimple hexagonalpatch,hexagonal patch with one triangular slot in ground for circular polarization. The circular polarization of two antennas are obtained with 1.31% axial ratio(AR) for simple hexagonal patch, 4.43% axial ratio hexagonal patch with slotted ground hexagonal patch antenna. The impedance band widths of these ...

In this paper, a complete design study of DualBand microstrip antennas (MSAs) using U-shape slotted patch with different feeding techniques is given and various methods of frequency control are also demonstrated. Investigations show that all the new designs are working in SBand with satisfactory radiation characteristics and impedance bandwidths. Key MSA, Dualband antenna, Frequency control, U-...

body centric wireless communication (bcwc) has been the topic of much research in recent years. in this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communications with a dual-band operation. the proposed structure exhibits a monopole-like radiation pattern at 2.45ghz and a broadside radiation at 4.8ghz, simultaneously. lateral dimensions of 42 mm × 46 mm a...

A single layer monpole slotted patch antenna is thoroughly simulated in this paper. Resonant frequency has been reduced drastically by cutting three equal slots which are same hexagonal structure at the upper right, upper left, lower left corner and a circle at the center from the conventional microstrip patch antenna. It is shown that the simulated results are in acceptable agreement. More imp...
