This paper presents coaxial feed rectangular microstrip patch antenna. A narrow Lshaped microstrip antenna is fed at the corner using a coaxial feed to obtain a LP operation. Experiments are carriedout to investigate its return loss, its radiation and its time domain behavior, which exhibit good radiation pattern. The simple rectangular and compact L-shaped microstrip antenna is simulated with ...

Conventional microstrip antennas in general have a conducting patch printed on a grounded microwave substrate, and have the attractive features of low profile, light weight, easy fabrication, and conformability to mounting hosts [1]. However, mi-crostrip antennas inherently have a narrow bandwidth, and bandwidth enhancement is usually demanded for practical applications. In addition, applicatio...

This paper describes the development and performance of a wideband dual linear polarization microstrip antenna array used in the Danish high-resolution airborne multifrequency polarimetric synthetic aperture radar, EMISAR. The antenna was designed for an operating frequency of 1.25 GHz 50 MHz and was built as an array of 8 2 probe-fed stacked microstrip patches. The feeding network is construct...

In this paper, compact antenna has been designed that can be implemented in a 2X2 Multiple-Input MultipleOutput (MIMO) system. A microstrip patch antenna fed by a microstrip line is designed for a frequency of 2.4 GHz used for industrial, scientific and medical (ISM) band applications. Polarization diversity of the two antennas is used to construct independent and uncorrelated signals on each a...

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...

The C and X band ranges of operation have wide range of applications which include satellite communications, Terrestrial communications and motion detection. In this paper we simulated and presented the results of radiation pattern, return loss, power dissipation and quality factor of stacked Microstrip patch antenna which operates in C and X bands. The results of antenna are simulated by using...

In this paper, we propose a novel microstrip antenna for operating over a three frequency bands, covering the 2.4/5.2/5.8 GHz WLAN and 2.5/3.5/5.5GHz WiMAX bands. The proposed antenna occupies an area of 30 mm  40mm, when printed on FR4 substrate (εr=4.4, h=0.8mm). The antenna comprises of a triangular patch section, L-shaped parasitic elements on the edges of triangular patch and a 50Ω micros...

AbstractThis letter represent a symmetrically notch loaded stacked circular half disk patch antenna. It is found that the bandwidth of the antenna depends directly on the notch dimensions. Bandwidth of the notch loaded stacked circular half disk patch is found to be 44.56 %. This antenna can be applicable for Wireless Local Area Network and ISM Band. Two parallel notches are incorporated to per...

Microstrip patch antennas represent one family of compact antennas that offer a conformal nature and the capability of ready integration with communication system’s printed circuitry. In this project, a 2.4 GHz circular polarization microstrip antenna is designed, constructed and measured. The selected microstrip antenna is a dual –fed circular polarized microstrip antenna. The antenna consists...
