A COMPREHENSIVE REVIEW ON BANDWIDTH IMPROVEMENT APPROACHES OF MICROSTRIP PATCH ANTENNA (MPA)

Abstract

 The field of wireless communication is developing very rapidly at present. With the development of the field of wireless communication, more compact size devices have been required that can produce more ICs in short space. As a result, antenna designers pay more attention to the microstrip patch antenna for its various advantages, such as compact size, low profile, high reliability, low cost, etc. MPA has demerits, too, for certain advantages. The significant drawback is lower bandwidth. Because of these antenna manufacturers, more attention is given to designing small broadband antenna sizes. In the last decade, literal analysis has been implemented to increase the bandwidth of the MPA. The aim of this paper work is to demonstrate a study on different MPA bandwidth enhancement techniques such as slot technique, air gap technique, multiple radiating element technique, parasitic patch technique, multiple feeding technique, proximity couple technique, and comparative analysis between them.
