Research study published in international journal of research
My second research paper, which got published in october 2014, microstrip antenna is a small compact antenna used in mobile phone mainly for effective communications.
Abstract
This paper demonstrates the design of a rectangular probe feed microstrip patch antenna for frequency specific wireless applications operating in the frequency range of 4.2Ghz to 5Ghz.Use of higher bandwidth in microstrip has been possible by using different methods of patch construction but this antenna aims at specific short band of 0.7Ghz to be used only at desired centre frequency of 4.85Ghz. The antenna has a good gain of 7.9209db and directivity of 8.0019db.It has Voltage standing wave ratio less than 2 and is very easy to be constructed.
Introduction:
The huge demand of wireless communication system and their miniaturization has made
antenna design more challenging. Recently
microstrip patch antennas have been widely
used in satellite communications, aerospace,
radars, biomedical applications and reflector
feeds because of its inherent characteristics
such as light weight, low profile, low cost,
mechanically robust, compatibility with
integrated circuits and very versatile in terms
of resonant frequency. The patch antenna
model used for the numerical simulation in
Ansoft HFSS is shown below. In this paper the
patch antenna is designed for 5GHz operation
on a substrate with 2.2permittivity and
0.32mm thickness.The patch with the coaxial
feeding was simulated in AnsoftHFSS.It has a
bandwidth of 4.5Ghz to 5.2Ghz.
the antenna is practically in use and is functioning as desired. the full paper can be downloaded by visiting this link.
