Compact Ultra Wide Band Antenna for Wireless Applications

The experimental study and design of a triangular microstrip antenna with V-slot is presented in this paper. Triangular patch on a FR4 substrate is designed having thickness of 0.6 mm and relative permittivity of 4.4 and it is mounted at a height of 5.5 mm above the ground plane. Bandwidth as high as 9.17% are achieved with stable pattern characteristics, such as gain within its bandwidth. This technological design is achieved by the two narrow slots embedded on the microstrip antenna in V shape and placing a single feed. Antenna gain, Impedance bandwidth and return loss are examined for the proposed antenna. This antenna was designed on Ansoft HFSS v-11.1.1 software. Details of the deliberated and simulated results are presented and discussed.
