Abstract
A multishaped beam direct radiating array antenna has a network on which high power beam forming sub-networks are disposed. The network is interposed between radiating elements and RF power amplifiers. This antenna is in addition constituted with a traditional network in which power combiners, phase shifters and inter-connection lines are provided. The most significant feature is that, with the help of the high power beam forming network, the correct amplitude and phase values, at the radiating element level, may be achieved without differentiating the RF power amplifier output levels, thus keeping its efficiency as high as possible. One of the advantages this configuration presents is the possibility to utilize only one antenna in comparison of the previous techniques in which the same results were obtained utilizing many radiating panels.
