Design of Rectangular Patch Antenna for Multi Band Applications
Abstract
This paper presents a detailed explanation on slot loaded Microstrip rectangular patch antenna for dual and multi frequency0applications. The antenna operates in C, X and Ku Bands. The antenna has been designed and simulated on a Rogers0RT Duroid 5880 substrate0with dielectric constant0of 2.2 and thickness0of 1.575 mm. In clear this paper proposed two design models. first design is rectangular microstrip patch0antenna for dual band0applications and the second one is that, the design of0rectangular microstrip patch antenna (MPA) for multi band0applications. The simulated return losses obtained for model 1 are -26.66dB at 6 GHz (C Band), -20.08 at 10.6 GHz (X Band), obtained VSWR (Voltage Standing0Wave Ratio) value is 1 at 6 Ghz, 1.72 at 10.6 Ghz and the gain value are 8.47 dB at 6GHz, 9.44 at 10.6 GHz. The simulated return losses for model 2 are -31.12 dB at at 6 GHz, -20.46 at 10.69 GHz and -35.20 at 14.10 GHz, obtained VSWR values for model 2 are 1.07, 1.21 and 1.07 and the gain values are 8.39 dB, 9.50 dB and 8.16 respectively. The0obtained VSWR values0are ˂2 (ideal case0is 1). The design is0analysed by Finite0Element Method based HFSSSimulator Software (version 14.0), the simulated0results shown that the proposed0antenna provides good0performance in term of return0loss, 0VSWR and gain for dual and multi frequency0applications.
