Radiation Pattern of the antennas is necessary for many applications in the telecommunication field, such as wireless communications and radar. They lessen the interference by channelling the radiation of antenna to the interested direction to achieve the enhancement of spectrum efficiency and multipath propagation reduction that results in the saving of radiation power and the increase in gain. Various techniques have been used to implement beam steering for several years. Electromagnetic band gap (EBG) with unique features helps to prevent/assist the electromagnetic waves propagates in a specific band of frequency for all polarisation states and all incident angles. In this paper, the advantages of the EBG surface wave band gap feature were identified, if it is inserted with microstrip antennas design, which helps to rise the gain of antenna, reduce the back lobe and lessen the mutual coupling in array components. Additionally, more advantages due to the surface waves suppression and the stopping band and passing band of the EBG have been achieved in the beam steering by integrating the single patch microstrip antenna with EBG. Additionally, the new antenna structure based on the combination of the concept of a reconfigurable planar array antenna with the EBG elements requires further research to produce a new radiation pattern control technique.Downloads
