In this proposed article authors present the design, analysis and development of the hybrid shaped multiband microstrip patch antenna for various wireless communication applications. Multiband characteristics of the proposed antenna is achieved by modifying the conventional circular radiating patch into “DUMBBELL” shaped hybrid patch geometry along with slotted reduced finite ground plane. A circular shaped reference patch is modified into dumbbell shaped patch by loading another circular shaped patch. Initial ground plane of same dimension as substrate is first decreased in width and four rectangular shaped slots are loaded in the appropriate locations to construct the final ground plane. Physical and electrical dimension of the proposed antenna are 24 mm  40 mm  16 mm and 0.18  0.3  0.12 where represents wavelength corresponding to lowest operating frequency of 2.3 GHz. Proposed antenna is designed using FR-4 substrate (1.6 mm thick, loss tangent (tan) of 0.02, dielectric constant (r) of 4.4) and simulated by CST Microwave Studio software. Antenna prototype is fabricated, measured and compared with the simulated results. The proposed hybrid shaped antenna exhibits measured multiband characteristics (2.3-2.5 GHz, 2.6-3 GHz, and 6.9-7.1 GHz) with centre frequency at 2.4, 2.7 and 7 GHz. Observed Reflection Coefficient, efficiency, peak gain and E plane and H plane radiation pattern of the antenna are very close to simulation result. Antenna can be suitably used for 2.4 GHz Wi-Fi and Bluetooth application, 5G mid band spectrum (3 GHz) and 7 GHz VSAT applications as well.
