Abstract: With the development of life and the need for more resources (electricity, gas, water and etc.) is increased, some companies began to provide these resources to each household, school, and office. These companies install meters in each consuming place and assign someone to get the reading of that meter. With the increase of buildings, households, offices that use this meter, it’s inappropriate to assign one or even hundred of people to check measured values. To solve these problems, various remote meter reading systems have been proposed.

Abstract: The microstrip patch in its pure form cannot satisfy the bandwidth requirements for most wireless communication systems. The general philosophy of most of the bandwidth enhancement techniques is to add one or more resonant structures to the microstrip patch configuration. These additional elements may be in the form of slots or other patches. This thesis introduces the design and analysis of bandwidth enhancements for a microstrip patch antenna using different slot configurations.

Abstract:Despite the numerous advantages, microstrip patch antennas suffer from narrow bandwidth which is approximately within 3-6% of the central frequency, one of the efficient methods used for the enhancement of MSPA
