This paper presents the design and development of proximity coupled equilateral triangular microstrip antenna using inverted U- shaped slot loading for triple band operation. The antenna operates between 2.75 GHz to 8.38 GHz range. The antenna gives a maximum impedance bandwidth of 6.50%. The substrate used for design of antenna is glass epoxy material (∈r =4.2). The microstripline feed arrangement is incorporated to excite the antenna. The proposed antenna shows broadside radiation characteristics. The design of the antenna is described. The simulated results are presented and discussed. These antennas are useful for the applications such as WIFI (wireless fidelity), IMT (International mobile telecommunication) and in radar.
