A triple band scalene triangular microstrip patch antenna

In this paper, a scalene triangular microstrip patch antenna has been designed which generates three resonating frequency bands. The scalene triangular radiating patch of the antenna has dimensions of (35, 45 and 55mm) respectively. The radiating patch has an L-slot, which along with the probe position has been optimized, so that it could generate desired resonant bands for tri-band application. The HFSS version13 simulation software is used to design and analyze the antenna over (1-5GHz) frequency range. The three frequency bands generated by the antenna are (1.64-1.76 GHz), (2.97-3.1 GHz) and (3.9-4.95 GHz). The application bands covered within generated frequency bands are (1660.5 - 1668 MHz) for Radio astronomy, (1668.4 - 1670 MHz) for Meteorology Radio astronomy, (1670- 1675 MHz) for MSS Earth stations, (1675 -1690 MHz) for Land military systems, (1690- 1700 MHz) and (1700 - 1710 MHz) for Weather satellites, (2.9-3.1 GHz) for Radiolocation (civil, military), (4.2-4.4 GHz) for radar altimeter and (4400–4990 MHz) for Aeronautical military systems.
