The proposed antennas are intend to utilize between 3 to 12 GHz.It consists of a Microstip patch, substrate and a ground plane. The characteristics of the antenna are mentioned. Microstrip antennas have a narrow bandwidth, so bandwidth enhancement is sometimes demanded for sensible applications. Additionally, applications in contemporary communication systems typically need compact antenna size so as to satisfy the miniaturisation needs of mobile units. Thus, size reduction and bandwidth enhancement have become major prototype issues for sensible applications of microstrip antennas . Microstrip or patch antennas are becoming to be more and more valuable on the grounds that they will be printed specifically onto a board. They’re broadly speaking used as a vicinity of flying machines, satellites, mobile, wireless application wherever size, weight, cost, easy installation, mechanics profile area unit constraints, and low profile like Micro strip antennas is also required. This thesis has the design of Microstrip antennas for wireless applications. Three antennas designed. The first design is a Dual band Microstrip antenna which produces dual band characteristics. The second design is a Wideband Microstrip antenna that has wideband characteristics and the third antenna is a Circular Disc Monopole Antenna for ultra wideband applications
