Abstract
This paper presents the tri-band slot loaded patch antenna for mobile communication. The antenna consists of parallel slots loaded circular disk with defected ground structure antenna (DGS). The antenna without DGS, acts like wide band antenna and bandwidth is 34.45% (3.47 - 4.92 GHz) with maximum gain of 4.97 dBi, which can be used in WiMax application. This structure has the following advantages: 1) co-axial feeding technique, which is very simple as compared to other feeding technique, 2) simple and cost effective and 3) it is more efficient than the antenna without DGS. This antenna has been analyzed using IE3D simulation software.
Highlights
Slot loaded circular disk antennas, with defected ground structure for WLAN, WiMax systems, mobile phone, radar, have been reported by several researchers [1]-[4]
Multiband antenna will have multi frequencies which can be used in different systems at the same time, the work related to tri-band antenna and multifunction applications have been published by several researchers
We found that the results like broadband antenna with frequency range (3.47 - 4.92 GHz) and central frequency 4.20 GHz
Summary
Slot loaded circular disk antennas, with defected ground structure for WLAN, WiMax systems, mobile phone, radar, have been reported by several researchers [1]-[4]. Their work is confined to only single band, double band and wideband, which is not suitable for current market demands. In order to overcome the market needs, a multi-band antenna with simple, low cost and solid structure is necessary [5]. Multiband antenna will have multi frequencies which can be used in different systems at the same time, the work related to tri-band antenna and multifunction applications have been published by several researchers.
