A new compact design of a planar phased-array antenna with inherent frequency selectivity properties is presented. In previous works, starting from an array of connected dipoles, the design of a filtenna structure and a strategy for the suppression of common-mode resonances have been addressed. In the present approach, a compact design solution has been obtained by the integration of part of the filtering function in the common-mode rejection module, consisting in a planar hybridring. As proved by simulation results, scanning up to 45 ° for the H-plane and up to 30 ° for the E-plane is achieved with a relative bandwidth of 21%.

Abstract
A new compact design of a planar phased-array antenna with inherent frequency selectivity properties is presented. In previous works, starting from an array of connected dipoles, the design of a filtenna structure and a strategy for the suppression of common-mode resonances have been addressed. In the present approach, a compact design solution has been obtained by the integration of part of the filtering function in the common-mode rejection module, consisting in a planar hybridring. As proved by simulation results, scanning up to 45 ° for the H-plane and up to 30 ° for the E-plane is achieved with a relative bandwidth of 21%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
