  7. Abstract:
  8. Today's millimeter imaging has been widely used in the field of security and medicine. With increasing security threats, there is a need for improved security equipment. Millimetric waves not only have the ability to penetrate dielectric materials, but also the ability to separate them to detect hazardous materials. Also, the millimeter-field imagery is capable of detecting different materials from each other, which is an advantage in detecting hidden cases. Unlike X-ray imaging, millimeter waves do not have the ability to ionize the cells of the body, which reduces the risk of creating radios for imaging. In this project, an array antenna with two orthogonal poles is designed. Macrostrip antennas are used in many telecommunication applications due to their lightness and low cost in terms of construction. Microwave strobe antennas have different types and each has its own advantages and disadvantages. The iron adapter used in this project is a microstrip antenna with a ground patch. To increase the radial gain, an antenna array is composed of microspheres with a ground patch that has two linear polarities vertically. In each section, the results of each simulation are reported
