Abstract :

The design of multiband microstrip patch antennas has become essential for emerging 5G communication systems. 5G technology requires compact antennas with wide bandwidth, high gain, and multiband operation. This research focuses on designing a microstrip patch antenna integrated with an Artificial Magnetic Conductor (AMC) surface to enhance performance characteristics. The AMC structure is used to suppress surface waves and improve radiation efficiency. The proposed antenna operates efficiently across multiple frequency bands relevant to 5G sub-6 GHz and mm Wave bands. The design process employs parametric analysis to optimize antenna dimensions. Simulation is performed using electromagnetic solvers. The antenna shows improved bandwidth compared to conventional patch antennas. Gain and radiation patterns also meet 5G communication requirements. The use of AMC significantly reduces back-lobe radiation and increases directivity. The compact size makes it suitable for mobile and base stat
