DUAL-BAND DUAL-POLARIZED MICROSTRIP STACKED PATCH ARRAY ANTENNA

摘要

PURPOSE: A microstrip stack patch array antenna is provided to improve a broadband frequency range property and an antenna gain by forming a plurality of microstrip patch array antennae in a stack structure. CONSTITUTION: A ground is formed in the lower surface of a first substrate(110). A first foam substrate(120) is laminated on a first substrate. A second substrate(130) is laminated on the first foam substrate. A second foam substrate(140) is laminated on the second substrate. A third substrate is laminated on the second foam substrate. A first microstrip patch is formed in the upper surface of the first substrate. A first parasitic patch is formed in the lower surface of the second substrate. A second microstrip patch is formed in the upper surface of the second substrate. A second parasitic patch is formed in the lower surface of the third substrate.
