Properties of multi-antikaonic nuclei (MKN), where several numbers of K{sup -} mesons are bound, are studied in the relativistic mean-field model, combined with chiral dynamics for the kaonic part of the thermodynamic potential. The density profiles for nucleons and K{sup -} mesons, the single particle energy of the K{sup -} mesons, and binding energy of the MKN are obtained. The effects of the K-K interactions on these quantities are discussed in comparison with other meson ({sigma}, {omega}, and {rho})-exchange models. It is shown that the K-K interactions originate from two contributions: One is the contact interaction between antikaons inherent in chiral symmetry, and the other is the one generated through coupling between the K{sup -} and meson mean fields. Both effects of the K-K repulsive interactions become large on the ground state properties of the MKN as the number of the embedded K{sup -} mesons increases. A relation between the multi-antikaonic nuclei and kaon condensation in infinite and uniform matter is mentioned.
