This document presents the design and development of a slits loaded equilateral triangular microstrip antenna for triple band operation between 5.37-9.26 GHz. The antenna is fabricated on a low cost glass epoxy substrate and incorporates microstripline feed to excite the antenna. Experimental results show the antenna operates over three bands with a maximum bandwidth of 3.83% and peak gain of 3.14 dB. Additionally, a notch band from 6.14-9.14 GHz is achieved. The simple, low cost design makes this antenna suitable for applications such as IEEE 802.11a and C-band systems.
