A STUDY OF 15 degrees-75 degrees-90 degrees ANGLES TRIANGULAR PATCH ANTENNA

In this paper, a triangular patch antenna (TPA) with 15 degrees-75 degrees-90 degrees angles is studied. The simulation results, using the full wave simulator, IE3D, for this TPA shape are compared with those for the equilateral triangular patch antennas (ETPA), the right angle isosceles triangular patch antenna (RAITPA), the 30 degrees-60 degrees-90 degrees TPA and 30 degrees-30 degrees-120 degrees TPA. It is found that for the same resonant frequency, the 15 degrees-75 degrees-90 degrees TPA occupies the least area among these triangular shapes. In an attempt to verify the simulation results, a 15 degrees-75 degrees-90 degrees TPA operating at 900 MHz is designed, fabricated, and measured. The measured value for the resonance frequency is very close to the value obtained by simulation. Finally, a 15 degrees-75 degrees-90 degrees TPA with a shorting pin is investigated. As expected, a miniaturized patch is obtained by loading a shorting pin at the tip of the patch.
