Objectives: To improve the antenna parameters for 3.5GHz WiMAX frequency by introducing slotted H-shaped patch with Dumbbell (H) shaped Defective Ground Surface (DGS).

Methods/analysis: In wireless communication, microstrip patch antennas are playing a vital role in various wireless applications. Worldwide Interoperability for Microwave Access (WiMAX) has been widely used in voice, data, video and internet access. WiMAX can able to provide above 100Mbps data rates.

Findings: The proposed antenna has symmetrical properties and has been designed by a dumbbell (H) shaped DGS on Flame Retardant-4 (FR-4) substrate fed up by microstrip feeding. The dimension of the designed antenna is 29×35×1.56mm. It radiates at 3.5GHz WiMAX frequency.

Improvements/Applications: The designed antenna offers improved antenna parameters for 3.5 GHz WiMAX applications.
