Abstract

A compact pot-shaped Multiple Input Multiple Output (MIMO) Antenna with Triple notched band characteristics is presented for Ultra Wide Band (UWB) Applications. The comprehensive dimension of the presented antenna is 17×32 mm². The presented antenna has two identical pot-shaped radiators, 7-shaped stubs, T-shaped strips, M and C-shaped slots. Two novel 7-shaped stubs are connected to the antenna ground plane to obtain -22 dB enhanced isolation. The presented antenna works from 2.95 to 12.1 GHz with triple stopped WiMAX, WLAN, and X bands. A novel T-shaped strip is connected to the antenna ground plane to stop the WiMAX band (3.3-4.4) GHz. C and M-shaped slots are etched in the antenna radiators to stop WLAN (5.20-6.12) GHz and X (7.6-8.15) GHz bands respectively. The peak gain of the proposed antenna is from 1.5 to 5 dB with a radiation efficiency of 80-90%. The Envelope Correlation Coefficient (ECC) of the proposed antenna is less than 0.01 with a Diversity Gain greater than 9.99 except for the notched bands.
