ABSTRACT:
A crossed slot fed microstrip antenna (100). The antenna (100) includes a conducting ground plane (125), which has at least one crossed slot (125), and at least two feed lines (105). The feed lines (105) have respective stub regions (115) that extend beyond the crossed slot (125) and transfer signal energy to or from the crossed slot (125). The antenna (100) also includes a first substrate (150) disposed between the ground plane (120) and the feed lines (105). The first substrate (150) includes a first region and at least a second region, the regions having different substrate properties. The first region is proximate to at least one of the feed lines (105).
