Quardport Grass-Hook Structured MIMO Antenna for Triband Frequency Applications

Abstract

The Grass–Hook shaped MIMO antenna having Asymmetric coplanar strip (ACS) feeding is designed with the dimensions 50 x 50 x 1.6 mm3.The tri band characteristics of antenna are used for the applications WLAN / WiMAX / LTE / Zigbee / Wi-Fi / Bluetooth / RFID. The operating frequency ranges are 2.25–2.47 GHz, 3.42–3.60 GHz and 4.59–6.65 GHz respectively. The results of antenna obtain Correlation Coefficient (ECC) value below 0.001, Diversity Gain >9.95 and CCL lower than 0.4 bits/s/Hertz. The designed antenna is efficient in reducing coupling and correlation within the antenna elements with the isolation result of <-17dB.
