Abstract :
This paper proposes an antenna directivity control method of adaptive array antenna for secure wireless transmission by dividing the transmitted information into pieces of divided-information and sending each pieces of information in a spatially distributed manner along multiple paths in a wireless space. Based on the DCMP weight control algorithm, the authors propose an antenna directivity control method not only to steer its main lobe to one targeted path but also to suppress other side lobes to suppress unnecessary signal radiation. Computer simulation confirms that by suppressing the side lobes of the antenna directivity, the transmitted signal power can be concentrated along the targeted path. It is effective to provide multiple transmission routes for signal delivery in the wireless space. Therefore better performance in regard with the secrecy of the transmitted information can be achieved in the wireless space by sending the transmitted information in a spatially distributed manner along the selected paths between the sender and the destination.
