Microstrip millimeter wave antenna study

The study was conducted primarily to investigate the feasibility and potential of integrating the front-end mixer circuit of a millimeter wave receiver into a microstrip antenna array. Development was concentrated in three areas: Investigate the practicality of conformal microstrip antennas in the millimeter wavelength region; specifically a 32 X 32 element array operating at 38.4 GHz was designed, fabricated and tested; Investigate possible designs for a front-end mixer circuit (i.e., local oscillator and mixer) which are compatible with the goal of incorporation into the microstrip antenna array; Design, fabricate, and analyze candidate circuits; and Integrate candidate front-end circuit into microstrip antenna array.
