Antennas must operate in a complex environment and fulfill the requirements on the other parts of the system. They also have their own requirements such as shaped pattern, size, weight, installation constraints and regulations that need to be considered. And then, there\u2019s the end use. For instance, the body design of a vehicle is a major part of a customer\u2019s interest in buying it; antenna placement won\u2019t likely factor into their design.<\/p>\n\n\n\n With complex electromagnetic environments, there is poised\nto be issues that need addressing long before producing and installing an\nantenna. There are three different classes of problems to consider:<\/p>\n\n\n\n Communication\/sensing system.<\/strong> Antennas don\u2019t work isolated in the deep space. They are installed on platforms, integrated in mobiles and personal computers, and many other locations. This means that designers must take into account the environmental effects on antenna performance at both antenna design and installation levels – for example, the interaction of an Advanced driver-assistance system (ADAS) radar antenna with the bumper may cause pattern distortion thus reducing ADAS radar performance.<\/p>\n\n\n\n As the number of electronics\nin products continue increasing, engineers must understand how electromagnetic\nperformance can potentially impact and interfere with product performance. For\nexample, electrical motors, sensors and antennas are more prevalent. These components\nplay a bigger role in the development process and must be part of electromagnetic\nsimulation<\/a>, which essentially means \u201cviewing the invisible,\u201d such as\nvisualizing E-H field, currents, charge, voltages and energy\/power distribution\nall along the 3D space.<\/p>\n\n\n\n Progress in the simulation technology means a comprehensive digital twin can provide valid support to address design issues in an effective and efficient way. Measurements are then used to tune the digital twin and to verify the performance of the final antenna and platform configuration.<\/p>\n\n\n\n The comprehensive digital\ntwin could also help simulate the exact 3D reality, allow designers and\nengineers to explore the design space and find trade-off solutions both at the\nantenna level and installation level, including minimizing interaction with\nsurrounding structures and interference with co-installed antennas and systems.<\/p>\n\n\n\n Just like simulation\ntechnology applied in other disciplines, electromagnetic simulation can be used\nfor multiple purposes like analysis, diagnostic, support to measurements\ndefinition, measurements understanding and support to certification.<\/p>\n\n\n\n Finally, simulation\nallows for faster prototyping and more efficient exploration of the space of\nsolution in the early design phase, when no hardware is available, and can\nassess the effect of the aging of materials, conductors, the effect of the\nmodification of the electromagnetic environment as well as the impact of the\nphysical environment. It also can minimize acceptance, qualification and\ncertification failure risk.<\/p>\n\n\n\n Without simulation, autonomous\nvehicles would have to be tested on 11\nbillion of miles of road<\/a> \u2014 an unrealistic and impossible task. Simulation\nis helping reduce the process from months down to days. That\u2019s why developers\nare increasingly using digital twin and simulation to test and validate antenna\nsystems. Problems are less expensive and time consuming to solve because issues\nare identified\nsooner in the development process.<\/p>\n\n\n\n Comprehensive and\ncollaborative software and solutions are part of the Siemens Xcelerator\nportfolio and can help developers use simulation and digital tools efficiently\nand effectively.<\/p>\n\n\n\n Learn more about Xcelerator at https:\/\/www.sw.siemens.com\/portfolio\/<\/a> <\/p>\n\n\n\n![\"\"](\"https:\/\/blogs.sw.siemens.com\/wp-content\/uploads\/sites\/19\/2020\/01\/Electromagnetic-Antenna.jpg\")
