Abstract

Conformal antennas are required whenever an antenna has to conform geometrically to some shaped surface. In this paper a cylindrical conformal antenna array with line feed technique is implemented. At first, an inverted U- slotted non conformal circular patched antenna with a radius of 16.3 mm, thickness of 1.6 mm, and a substrate permittivity of 4.4 is designed to operate at 2.4 GHz. The simulated results are in close agreement with measured results. The measured S11 for non-conformal antenna is -17.4 dB at 2.4 GHz. The inverted U-slotted circular patch antenna is made conformal to cylindrically bent substrate of thickness 0.762 mm with a permittivity of 2.55 and it resonates at 2.63 GHz. Further, an array of three elements of conformal U-slotted circular patch antenna flush mounted on cylinder 1200 apart. From the results, it is evident that gain is increased with cylindrical conformal array antenna. The gain of proposed conformal array antenna is of 5.02 dB. Simulation is carried out using HFSS software.
