A Novel Compact and Wideband Multi U-Slotted Microstrip Antenna
A new compact and wideband multi U-slotted microstrip patch antenna with improved bandwidth is presented in this paper. The antenna is resonating at the center frequency of 4.2GHz with return loss of -40dB. The proposed antenna provides an impedance bandwidth of 110% and VSWR less than or equal to 1.02 which is close to unity. The proposed antenna is excited by coaxial feed and analyzed by using HFSS software. The proposed multi U-slotted microstrip antenna is suitable for Bluetooth, Wi-Fi, WLAN and WiMax wireless communications.
