Elson Agastra - Academia.edu A ground-backed slim slot-sinuous antenna is analyzed. Proposed configuration allows for a single lobe, polarization-versatile, high efficiency and ultra-wide band antenna not needing a the cumbersome lossy back cavity typical of conventional single lobe sinuous antennas. Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications. ... Although the patch antenna needs high gain RTDs due to ... Spiral Antennas - Antenna Theory Spiral Antennas. This means that if the lower frequency is 1 GHz, the antenna would still be efficient at 30 GHz, and every frequency in between. Spiral antennas are usually circularly polarized. The spiral antenna's radiation pattern typically has a peak radiation direction perpendicular to the plane of the spiral (broadside radiation).
