Abstract : The universal demand for compact handheld communication devices has increased significantly in the modern era. Devices with internal antennas have emerged to cater to this necessity of device miniaturization. Antenna size is a major factor that limits the manufacture of efficient small devices. Over the past few years, new designs based on the Micro Strip Patch Antennas (MSPA) have come to the fore for handheld wireless devices because these antennas have low-profile geometry and can be embedded into the devices. Antenna performance generally gets degraded on reducing the antenna size. It is henceforth also important to examine the fundamental limits and parameter trade-offs involved in size reduction. In the handheld environment, antennas are mounted on a small ground plane. This paper presents the performance analysis of Z shape Micro Strip Patch Antenna, by using different dielectric substrate materials, to operate in the frequency range of 0.6 GHz to 2 GHz. A systematic parametric analysis has been implemented using HFSS software to optimize the bandwidth of the proposed antenna. The aim of this paper is to broaden the impedance bandwidth along with the maximization of gain, thereby improving upon the performance of antenna.
