Senior Phased Array Antenna Engineer

EchoStar has an exciting opportunity for a Sr Phased Array Antenna Engineer in our Hughes Network Systems division for our office in Gaithersburg, MD . This is an exciting position where the candidate will be involved in design and testing of state-of-the-art RF and antenna technology for next generation LEO/MEO/GEO satellite communication systems for fixed and mobile applications.

Responsibilities:

• Analyze system requirements and derive antenna and RF sub-system requirements

• As member of antenna design team, conduct detailed design of low-cost radiating elements that work over wide bandwidths and wide scan angles in Ku and Ka bands

• Conduct extensive simulations of the design to predict performance in the field

• Actively work with mechanical and CAD teams and board manufacturers to get a protype built based on selected design

• Develop test plans and generate detailed test procedures for RF and phased array antenna subsystems.

• Conduct near field and far field measurements, collect results, analyze and present to internal teams and customers, when needed

• Analyze RF chain requirements for a user terminal based on phased arrays

• Interface with factory teams to provide antenna test fixture related inputs

• Interface with vendors and suppliers on the selection of test equipment for the antenna lab

Basic Requirements:

• MSEE in electrical engineering with emphasis on antenna and RF/microwave engineering

• Solid understanding of advanced electromagnetics, antennas, polarizers and radomes

• 10+ years of phased array design and testing experience in Ku and Ka bands

• 5+ years of experience with test equipment like vector network analyzers, spectrum analyzers, signal generators, noise figure meters, power meters etc.

• 5+ years of experience making antenna pattern measurements including active element patterns, gain, G/T, beam-width, sidelobe levels, co and cross polarization levels, Axial Ratio, Return loss, Insertion Loss, coupling factors.

• 7+ years of experience with simulation tools such as HFSS, CST, ADS and MATLAB

Preferred Qualifications:

• PhD in electrical engineering with emphasis on antenna and RF/microwave engineering

• Familiarity with a wide variety of RF printed circuit technologies including stripline, microstrip, CoPlanar Waveguide.

• Familiarity with high density PC Board interconnect methods including micro-via, blind and buried via, in RF and microwave environments.

• Familiarity with cavity resonance issues of enclosed antenna structures

• Knowledgeable about electronic beam forming, beam steering and array synthesis.

Will be eligible for discretionary bonus, with funding based on company performance.
