The geometrical design of the microstrip patch array antenna is simulated and executed using CST Microwave Studio (CST MWS) in order to study the effects of various antenna parameters such as S 11, gain, directivity, side lobe level, and angular width. For X-band communication transmission, it is necessary to suppress the side lobe radiation pattern of the antenna as much as possible to avoid the transmission being intercepted and/or received by undesirable neighbouring satellites. In this paper, a microstrip patch array antenna is designed and simulated to operate in the X-band frequency region at 9.5 GHz. Good agreement is found between the measurements and the simulation results.Array antenna, microstrip antenna, side-lobes suppression, X-band communication. The experimental measurements are done using the vector network analyzer (VNA HP8719Es). The fabrication is done using thin film technology and photolithographic technique. The antenna elements and the array are realized on the FR4 (lossy) substrate with dielectric constant ε r = 4.5, loss tangent of 0.025, and height h = 1.5 mm. In addition, a design for ultra-wide band (UWB) antenna element and array are introduced. The power divider is realized on Rogers R03010 substrate with dielectric constant ε r = 10.2, loss tangent of 0.0035, and height h = 1.28 mm.

The design of the antenna array and the power divider are made using the software package CST MICROWAVE STUDIO. These matching techniques are used to adjust the branches impedances according to the desired power ratio. The amplitude and phase of the signals emerging from each power divider branch are adjusted using stub and inset matching techniques. A new design for a four ports unequal circular sector power divider and its application to antenna array SLL reduction is introduced. For the synthesis of a radiation pattern, an unequal-split power divider is required. A power divider can be utilized as a feeding network of an antenna array. Power dividers play a vital role in various radio frequency and communication applications. The proposed antenna array system consists of two main parts, the antenna array, and its feeding network. In this paper, the hardware implementation of an antenna array system for SLL reduction is introduced using microstrip technology. This interference reduction increases the capacity of the communication systems. It is considered as one of the most important applications of digital beamforming since it reduces the effect of interference arriving outside the main lobe. Side lobe level (SLL) reduction has a great importance in recent communication systems.
