This paper presents a single feed rectangular micro strip patch antenna and a different approach to design dual and triple band antennas using triangular slots on patch. Three triangular slots are there for triple band in this design, two triangular slots are above the feed point one triangular is near the feed point. A triple band antenna for 3.65 GHz, 4.11GHz and 6.48 GHz applications using slot technique is presented. Results of simulation show that at 3.65 GHz, 4.11GHz and 6.48 GHz, the antenna has reflection coefficient (S11) as -16.68dB, 23.42dB, -21.67dB respectively. The simulated results along with the different parameters like radiation pattern, VSWR etc. are presented and discussed in this letter. The design and performance of antennas are carried out using HFSS 14.0 software. Main objective of this paper is to achieve the multiple resonances within the same antenna at desired frequencies so that this could be applicable in Wi-max applications. |
