Design and Comparison of a Compact Tapered Triangular Single and MIMO Antenna with Polarization Diversity for Wideband Applications
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 3
Abstract
In wireless communication applications high data rates is the prime requirement. This demand necessities the need of inclusion of more number of antennas in wireless applications. These systems require an antenna with optimum bandwidth and polarization diversity. This paper discusses a compacted modified triangular antenna that functions at 2.45 GHz. The modified tapered triangular antenna structure gives the miniaturization. Also adding partial ground enhances bandwidth of MIMO microstrip antenna. The structure to be designed is a 2×2, microstrip fed tapered triangular MSA. The patches are kept orthogonal to produce polarization diversity. Antenna to be implemented has been structured on FR4 substrate with dielectric constant of 4.4. The antennas are simulated and the results for triangular single and 2X2 MIMO antenna are compared. 2X2 multi input multi output design gives a large bandwidth from 1.58 GHz to 3.96 GHz corresponds to 99.16% impedance bandwidth at VSWR 2:1. The pattern for radiation of single tapered triangular antenna is directional and that for multi input multi output is nearly omnidirectional in azimuth plane and bidirectional in elevation plane. The antenna to be implemented possesses a gain of 3.3dBi with overall size very compact. This antenna is most suited for WLAN, Wi-Fi, & WiMAX applications.
