“…Recently by cutting two concentric U-slots inside rectangular MSA (RMSA), a dual and wide band response in two different frequency bands is reported [6]. The reported double U-slot cut RMSA covers AWS, GSM, WiMAX and WLAN frequency bands (1710 -1755 MHz, 1805 -1880 MHz, 1900 -1990 MHz, 2.110 -2170 MHz, 2400 -2500 MHz, 5150 -5350 MHz, and 5450 -5850 MHz) [6]. To cover these various frequency bands, dual and wide band operation is needed in 1700 -2500 MHz (BW ~ 38%) and 5150 -5850 MHz (BW ~ 14.5%) [6].…”
