Design of mmwave conformal linear array antenna

The paper presents the design and analysis of linear arrays of mm-wave conformal patch antenna (MPA) designs. It has a methodology where 37.8 GHz is first designed and later expanded to a four element and five element planar arrays on its superior features. The reflection coefficient, radiation patterns, near-field characteristics and the distribution of current are investigated. The conformal properties are investigated based on the bending analysis of the array setup in a way of assessing the feasibility of the proposed array set up. The 4-element linear array has resulted in a stable frequency response with a little variation during bending, whereas the 5- element linear array has shown the improved gain, but it is also sensitive to feed and deformation effects. The suggested linear antenna arrays boast of a good balance of gain enhancement, area and conformal suitability rendering it suitable to the mmWave applications.
