Abstract

In this work, the design of a millimeter-wave conformal antenna array for cylindrical structure is developed. Antenna array consists of 4×4 elements and operates at 60 GHz. Different substrates and their properties are considered. Fiber Teflon substrate was chosen for the antenna structure due to its good flexibility properties and low losses. The performance of the antenna array is simulated with Ansoft HFSS™ software. Simulation results for planar structure and bent along a cylinder axis are presented. Conformal antenna array structure has wider beamwidth but the realized gain value decreases from 19.2 dB to 12.8 dB. Placing two antenna arrays on the cylindrical surface, which allows achieving high gain value and at the same time covering large angular region, are also presented.
