Antenna Miniaturization Using Fractals Richa Garg, AP ECE Deptt., [email protected], J.C.D.C.O.E., Sirsa ABSTRACTThe use of fractal geometry in designing antenna has been a resent topic of interest. Fractal shape has their own unique characteristics that the improved antenna performance can be achieved without degrading the antenna properties. Modern telecommunication system requires antenn...

Wireless communication has been developed rapidly in the past decades and it already has a great impact on human life. In the field of wireless communications, antennas play a vitally important role. In the late 1970s, there was rapid development in the field of microstrip patch antenna technology. In early 1980s, antenna elements and arrays were developed in terms of design and modeling. Due t...

This article presents an overview of the microstrip patch antenna and its design techniques. Basically a microstrip patch antenna comprises of a trace of copper or any other metal of any geometry on one side of a standard printed circuit board substrate with other side grounded. The antenna is fed using various feeding techniques like coaxial, strip line, aperture coupling or proximity coupling...

In this paper, we present multiple L slots antenna for WIMAX and WLAN applications. wideband microstrip patch antenna for wireless applications. The coplanar waveguide fed microstrip patch antenna comprises of four rectangular patch array each embedded on three L slots and a Plus slot either on the patch or on the ground plane or on both the patch and the ground plane. The design results in red...

This paper presents a novel way for achieving endfire radiation pattern using microstrip patch antenna array. The extensively used microstrip patch antennas i.e. rectangular and circular microstrip patch antennas, either single patch or in an array configuration do not have an endfire radiation pattern. The antenna array presented in this paper is designed by changing the geometry of the antenn...

This paper describes the performance analysis of different feeding technique for wireless microstrip patch antenna i.e for wi-max applications. In this paper four types of feeding techniques (Microstrip line feed, coaxial probe feed, proximity coupled feed and aperture coupled feed) are used. From the four feeding techniques, microstrip line and coaxial probe feeds are contacting scheme, in whi...

This paper presents the design of rectangular, fractal Microstrip patch antenna and their backscattering reduction. These antennas have been designed on εr = 4.3, h = 1.53 mm substrate with rectangular patch dimension 36.08 x 29.6 mm and its 2 iterative fractal patch. The experimental resonant frequency of 2 iterative fractal patch is observed 2.11 GHz in comparison to rectangular patch 2.42 GH...

A common technique to realize wideband microstrip antenna is by introducing slots at an appropriate position inside the patch. In this communication a stacked configurated microstrip patch antenna with slots similar to ISI shape introduced on a square radiating patch with a microstrip line feed is presented. The slots introduced in the radiating patch of the proposed antenna increase the fringi...

Abstract: Microstrip antenna is low coast, light weight, and easy to connect with the electric circuit, but it have some drawbacks such as low bandwidth and low gain. In this paper planar microstrip antenna is proposed to enhanced gain and bandwidth. The new design is have modified ground plane and periodic patch. The bandwidth and gain are enhanced, when compared with the traditional rectangul...

In this paper, a new design technique for enhancing bandwidth that improves the performance of a conventional microstrip patch antenna is proposed. This paper presents a novel wideband probe fed inverted slotted microstrip patch antenna. The design adopts contemporary techniques; coaxial probe feeding, inverted patch structure and slotted patch. The composite effect of integrating these techniq...
