Senior Microwave Antenna Engineer



A microwave antenna design engineer will join our design team to lead the development of feed elements for a revolutionary low profile microwave lens-based phased array antenna for a range of applications emphasizing on-the-move and fixed two-way satellite communications (Satcom) with geostationary and non-geostationary satellites as well as 5G applications. The candidate should have a proven track record of antenna design experience at microwave thru Ka-band and above, with initial emphasis on Ku-band and K/Ka-band satellite terminals. These terminals feature low profile apertures with automatic electronic satellite acquisition and tracking with no moving parts, whether on-the-move or stationary installations that can track geostationary or non-geostationary satellites.. A distinguishing feature of Isotropic’s antenna terminals, compared for example with conventional phased arrays, is our ability to form simultaneous, independently steerable/pointable beams over a wide field of view without the attendant high cost of phased arrays that would require multiple separate beam forming networks for each beam.


Of particular importance is candidate’s appreciation of and proven performance history for high-efficiency and cost-conscious microwave antenna design, simulation and testing. The selection of microwave components, materials, and structures that maximize antenna efficiency will be critical to minimize costs for new products that are intended to be low cost disruptors into the Satcom markets.

While our technology incorporates an array of microwave feed antennas, it is excited differently from a phased array for beam tracking. Candidate should have a good understanding of the benefits and detriments of the various microwave antenna geometries, as well as how the behavior of the elements changes when operated in an array environment. Experience and exposure in the design of the feed network and active circuitry for a multielement terminal is also desirable. Experience in modeling antennas and circuit layouts including tolerance information and transitioning the designs to PCB or waveguide implementations is highly important. Knowledge and experience with multi-beam feed arrays (e.g. for reflectors) is useful insofar as similar techniques could be used for the focal region of a microwave lens aperture.

Education and Qualifications

Candidate must have a BS level degree with advanced degree preferred and at least 3-5 years’ experience in related activities.

Key Duties and Responsibilities

Successful candidate will work in a team to develop new microwave feed antennas using computational modeling and prototypes to verify performance and operation, including following through to product breadboarding, prototyping, testing, and manufacturing. Capabilities for design to cost and design for manufacturability are critical. The successful candidate will join a company that intends be a disruptive entry into the Satcom terminals market and affords substantial professional and technical growth opportunities.
