Abstract

Wrapped antennas are described as the omnidirectional coverage antennas, thus it has been discussed in wide studies. In this study shows how to calculate the radiation pattern for a wraparound microstrip antenna by solving the integral equation of the electric and magnetic fields. The modelling has been done by representing the body with regular geometrical shape such as a Body of Revolution (BoR). The wraparound microstrip antenna is considered as a conducing cylinder patch which be uniformly coated around a lossless dielectric having dielectric constant. Both are substrates around a conducing cylinder as ground patch. Analytically the prediction results have been calculated using the Method of Moment (MoM). It is worth noting that these predictions are in a good qualitative agreement with previous studies. We also has been examined the case involving two simultaneous patches using the electromagnetic boundary conditions to solve the differential and integral equations. These types of antennas are used in many applications such as medical, military as in the rockets, etc.
