Multiband Microstrip Patch Antenna for Wireless Applications

The project is named “ Multiband Microstrip Patch Antenna For Wireless Applications ” Multiband phased array antennas used in today’s multi-function communication applications. Generally microstrip antenna arrays like the kotch array and sierpinski array are used but in some circuits where space is limited and arrays are not used. Therefore to achieve the multiband operation with limited space an antenna is designed E-shaped in combination with a split ring resonator to achieve the multiband operation. The simulation and experimental results show that the projected antenna operates at four different frequencies, 1.8GHz, 3.6GHz, 4.53GHz, and 5.73GHz, which can be used for various wireless applications like GSM 1800 (1.71– 1.78 GHz), Wi-MAX (3.4-3.69GHz) -IEEE 802.16 standards, Wi-Fi/WLAN (5.15-5.82 GHz). All the simulation outputs like resonant frequency, return loss, radiation patterns and fabricated antenna measured result is presented in this paper. The antenna is simulated using CST 2014 software.
