The Antenna Specialist is responsible for designing, simulating, testing and documenting the best solutions possible for antennas in high volume manufactured cell phones. The antennas to be designed can include multi-band 700/750/850/900/1800/1900/2100/2600 MHz (some combination of these bands and other bands) cellular (GSM/UMTS/LTE/CDMA) internal antennas, multi-band cellular MIMO and RX diversity antennas, GPS/Glonass antennas, WLAN 2.4 and 5 GHz antennas, BLUETOOTH antennas and NFC antennas. The designs are described in terms of suitable SAR, HAC RF emissions, TRP, TIS, envelope correlation coefficient, radiation pattern, return loss, antenna efficiency in actual usage conditions, and isolation between antennas. Performing trade-off studies is required between antenna performance, RF performance, mechanical constraints, and marketing requirements.
Typical constraints are small size of the phone, low costs and specific form factors.
All the work needs to be done with seamless teamwork. Some other stakeholders are mechanical engineering, PWB design, RF design, the antenna manufacturer, the field test crew, product marketing, and management of the project.
In general, the antenna specialist must have competence in the design of antennas for almost all of the protocols and parameters listed above, and be an expert in some of them.
The Antenna Specialist is also responsible for leading the antenna design for projects, managing the antenna design process for a project including schedules, providing antenna recommendations to the project, and advising the more junior members of antenna group. The Antenna Specialist should have strong project management skills and can contribute to the high level project schedule. The Antenna Specialist should also some familiarity with the other HW disciplines so that recommended solutions are acceptable to the other HW disciplines.
The Antenna Specialist also is innovative and active in contributing new antenna ideas, solving antenna problems and defining antenna project contents. Participates in, and contributes to antenna reviews. Gives input regarding the development of antenna technology. Translates current and future customer/end user expectations to antenna solutions. Facilitates competence development, knowledge sharing and coaching and mentoring within antenna group.
Jobs of the subordinates of the employee:
May work with antenna test technicians, who will perform measurements and help build antenna prototypes. May guide and mentor more junior antenna design engineers.
The employee is guided by:
Project Development Manager and Antenna Stream Leader
Typical decision making and problem solving situations in the job:
Performing trade-off studies between antenna performance, RF performance, mechanical constraints, and marketing requirements. Giving input to influence the development of antenna technology. Translating current and future customer/end user expectations to antenna solutions.
Nature of the responsibility:
Responsible for selecting an optimal antenna design, which meets all the requirements, or providing multiple antenna designs and the trade-offs amongst them. Responsible for leading antenna designs, managing the antenna design process for a project including schedules, providing antenna recommendations to the project, and advising the more junior members of antenna group. Responsible for being innovative and active in contributing new antenna ideas, solving antenna problems and defining antenna project contents, participating in, and contributing to antenna reviews, giving input to influence the development of antenna technology, translating current and future customer/end user expectations to antenna solutions, facilitating competence development, knowledge sharing and coaching and mentoring within antenna design.
Minimum M.Sc. in Electrical Engineering or related degree/experience. Minimum 7 years of industry experience in practical design and testing of antennas or additional education in related field. Extensive knowledge in Electromagnetics and Antenna Theory for small antennas in portable devices. Good knowledge of mechanical and electrical material properties of antenna subassemblies. Knowledge and experience with antenna simulation.
Our culture is founded on openness, collaboration and honesty, with colleagues who are brilliant in their field, resilient, and above all, strive for the best. One team, where everyone makes a difference and everyone is heard. We care. Even in tough times. We are driven by a better tomorrow, not just by past success. We make great products and services for millions of people, positively improving their daily lives. We are on a path where simplicity and “thinking big” can lead to great things.
