A compact broadband antenna (10). The antenna (10) includes a first mechanism (12, 20) for receiving input electromagnetic energy. A second mechanism (26) provides radiated electromagnetic energy (46) upon receipt of the input electromagnetic energy. The radiated electromagnetic energy (46) is provided via an antenna element (26) with one or more angled surfaces (27). A third mechanism (14, 32, 28) directs the radiated electromagnetic energy (26) in a specific direction. In a more specific embodiment, the third mechanism (14, 32, 28) includes a reflective backstop (28) that is selectively positioned behind the second mechanism (26) to reflect back- radiated energy forward of the second mechanism (26), thereby causing reflected electromagnetic energy to combine in phase with forward- radiated energy (46) from the second mechanism (26). The third mechanism (14, 32, 28) further includes plural layers of dielectric material (14, 32). One or more of the plural layers (14, 32) of dielectric material partially surround an angled radiating surface (27) of the second mechanism (26), which is implemented via a substantially conical transmit element (26) in the specific embodiment. ® KIPO & WIPO 2007
