Popis: In this paper, a flexible, compact, and semi-transparent monopole antenna integrated with a 2×2 AMC reflector is presented for vehicular communication applications. F-shaped and inverted L-shaped stubs are connected to the radiator symmetrically with slots in the partial ground for making the antenna operate at a 5.85 GHz band. The antenna is designed using a flexible polyimide substrate (εr = 3.5, tanδ = 0.025) with dimensions of 14×14×0.5 mm3. An AMC reflector unit cell is designed using PDMS (Polydimethylsiloxane) substrate (εr = 2.66, tanδ = 0.023) with dimensions of 8×8×1 mm3. The AMC cell structure is designed with a split ring resonator (SRR) and rectangular ring with full ground resonating at 5.85 GHz. The 2×2 AMC reflector surface is integrated with a separation 9 mm to the designed antenna that provides the gain increment from 1.73 dBi to 4.56 dBi. The reflection coefficient S11 bandwidth of the AMC-backed antenna is 0.52 GHz, while the standalone antenna’s bandwidth is 0.44 GHz. The flexibility, compactness, and achieved radiation metrics project the proposed antenna structure a suitable choice for vehicular communication applications.
