We propose a new method to design miniaturized compact antennas, in which it is possible to control conjointly the radiation\nefficiency and the bandwidth selectivity of the antenna. And this method has been validated by the realization of prototypes based\non planar resonators. The geometry of these resonators has been chosen because their unloaded quality factor can be controlled\nand is mainly dependent on radiation loss. In the first time, a filter with a significant potential to radiation has been realized by\nchoosing suitable miniaturized resonators. An antenna, based on the same structure, in which the output of the filter was removed\n(load by air resistance) can be obtained. Modification of the quality factor of each resonator is necessary to take into account the\nchange of the load value from the previous filter to the final structure. The position and the quality factor of the resonators are\ndetermined by a filter design concept to obtain a specific frequency response in which each resonator is a basic radiation element.\nLoad of the antenna is ultimately a distributed load constituted by the parallel contributions of each resonators to radiation loss. In\nother words such an antenna can also be called radiating filter.
