Abstract—A micrsotrip patch antenna occurs is various shapes such as rectangular, square, circular etc, and is widely used in many portable communication devices today mainly because of its light weight and smaller size. But despite its use in many communication devices like cell phones, laptop computers, aircraft communication systems, there is further need to investigate how the conductance of this antenna varies with varying parameters of the antenna such as its frequency of operation and dielectric constant. This is the aim this work wants to achieve. The work employs transmission line model, and the various parameters of the antenna were gotten in two ways; one at constant frequency and changing dielectric constant values, and the other at constant dielectric value and changing frequency of operation. It was observed that the conductance of a rectangular microstrip patch antenna is higher at lower frequency and lower dielectric constant value, and vice versa. It was concluded that a rectangular microstrip patch antenna with lower values of frequency and dielectric constant conducts better than that with higher values of frequency and dielectric constant.
