A wideband and low side lobe series fed patch array at 5.8 GHz for radar applications
In this paper a novel series feed patch array working in the 5.8 GHz ISM band for healthcare radar monitoring applications has been proposed. The single patch has been opportunely shaped to solve two critical problems of this antenna topology: reduced bandwidth and high Side Lobe Level (SLL). The bandwidth enhancement has been obtained with a dual band structure, resulting from the superposition of two tapered patches with different lengths.
