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 ...

The transmission spectrum of fractal polyadic Cantor superlattice exhibits sharp peaks within forbidden frequency gaps. This property has been exploited by placing such self-similar multi-slab structure in the far field radiation region above a radiating element such as a patch antenna to maximize its directivity at the corresponding transmission peak. A patch antenna having directivity of 30 d...

A single feed compact square microstrip antenna is proposed in this paper. Two L slits are introduced on the right edge of the patch to study the effect of the slit on radiation behavior with respect to a conventional microstrip patch. An extensive analysis of the return loss, radiation pattern and efficiency of the proposed antenna is shown in this paper. For the optimize value of the slit par...

A compact Ultra wideband (UWB) antenna with bandnotched characteristic is presented in this paper. It has compact size of 30 mm x 31mm and has ultra wide band operation. A ‘C’ shaped slot was introduced to achieve band notch function from 4.8 GHz to 6 GHz to avoid interference from WLAN. The proposed antenna has ultra wide band frequency range from 3 GHz to 11.5 GHz for return loss below -10 dB...

Since the beginning of the human civilization mankind is trying to communicate with the others. It’s the communication process i.e. the sharing of feelings, emotions and information has made us the greatest creation of God on this green earth. It all started with hand gestures, then sounds. Communication. in wireless communication we mainly exploit the Electromagnetic Spectrum. Earlier systems ...

Design and analysis of a compact coplanar waveguide (CPW) fed Ultra Wideband (UWB) slot antenna is presented in this paper. The antenna consists of a rectangular slot with cross like structure at the anterior portion of the feed which acts as tuning stub. The CPW feed is designed for 50 Ω impedance. The physical dimension of the proposed antenna is 19mm (length) × 20mm (width) × 1.6mm (thicknes...

The radiation performance of a circular patch microstrip antenna having a concentric diamond shape slot has been presented in this paper. The side lengths and angles of the inserted diamond shape slot have been optimized to achieve a single layer multi frequency microstrip antenna applicable for C band space communication systems. For simulation work, IE3D simulation software has been applied a...

In current trend for portable wireless communication applications, we require high Q on-chip inductors. In this paper an on-chip 3-D spiral inductor is proposed. High quality factor is achieved by reducing oxide capacitance between substrate and conductor considering permittivity of a substrate. Losses in the structure are reduced by considering high conductivity material like copper or gold. I...

In this paper, two microstrip-fed printed slot antennas have been introduced to be used in modern communication systems, as alternatives for conventional Hilbert slot antenna. The slot structures of the proposed antennas are in the form of the 3rd iteration of two variants of the conventional Hilbert space-filling curves. These antennas are fed with 50 Ω microstrip line printed on the reverse s...

This paper presents the design of a 2.77GHz MIMO antenna with two rectangular patches loaded by two split ring resonator (SRR) as the antenna elements. Each antenna element has area of 56×25mm2. A compact and low correlation coefficient antenna system covering bandwidth 178MHz for wireless communication standards is proposed. First, a linearly polarized rectangular patch antenna is discussed. I...
