Design and analysis of multiband antenna for WiMAX and WLAN are presented. The designed antenna comprises of a triangular patch and six circular patches that are connected with the triangular patch using rectangular striplines which lies on the top plane of the loaded FR4 substrate. A defected ground structure is developed in this design to get isolation between WiMAX bands. A parametric study on the radius of circular patches and lengths of the rectangular microstriplines has been carried out on the designed antenna to afford all the crucial WiMAX operative bands (2.5/3.5/5.5 GHz). The designed antenna is compact (23 × 27 × 0.8 mm3) when compared with the previously proposed multiband antennas. The simulated and measured responses show that the antenna is proficient to operate among the 2.3–2.4, 2.5–2.69, 3.3–3.8, 4–4.7, and 5.425–5.850 GHz frequency bands. The design parameters have been analyzed and measured for validation.
