H-U-E Shaped Slotted Microstrip Antenna for Bandwidth Enhancement

An H-U-E shaped slotted microstrip antenna with improved bandwidth is presented in this paper. The antenna resonates in the frequency range of (2.0–6.3) GHz with the center frequency of 4.2 GHz. The proposed antenna provides return loss approximately -30 dB. The antenna is fed with coaxial feeding yields an impedance bandwidth of 103.6% and VSWR of less than 1.07. The proposed antenna is simulated using Ansoft's HFSS software. The proposed H-U-E slotted microstrip antenna is suitable for wireless communications.
