An antenna engineer designs and develops antennas and other communication devices. The duties of someone in this career include working with electronic equipment such as modems, cell phones, satellite equipment, and radio antennas. As an engineer, you may analyze a company’s needs and then make plans to meet those needs. Your responsibilities may include performing research, making a development schedule, and creating budget proposals for development projects. You often create prototypes of your designs for testing and then analyze performance. Many projects require an understanding of radio frequency (RF) ranges.
