High Gain Compact Strip and Slot UWB Sinuous Antennas Three ground-backed compact strip-and slot-sinuous antennas are analyzed. Proposed configuration allows for a single lobe, polarization-versatile, high efficiency, and ultrawide band antenna not needing a cumbersome lossy back cavity typical of conventional single-lobe sinuous antennas. Simulations show attained performances as well as tuning possibilities. (PDF) High Gain Compact Strip and Slot UWB Sinuous ...
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).
Abstract: A coplanar waveguide (CPW) center-fed four-arm slot sinuous antenna is introduced in this letter. The antenna demonstrates broadband characteristics in terms of its split-beam radiation pattern and angle of maximum gain as well as multiband characteristics in terms of axial ratio (AR), omnidirectionality, polarization, and return loss.

1.. IntroductionA sinuous antenna is a broadband, either planar or conical, rotationally symmetric and self-complementary structure composed of multiple zigzagging arms as described in .The limits of sinuous low- and high-frequencies are determined by the outer and inner diameters of the active antenna region, respectively .Most sinuous antenna research works have been devoted to four-arm ... Antenna | MVG Standard gain horns are used for gain reference for high gain antennas and antenna measurements. More details. VHF Wideband Low-Profile Antenna. 40.0 MHz to 400.0 MHz. Low profile reference antenna for measurements in VHF frequencies. More details. Wideband Dipoles. 75.0 MHz to 6 000.0 MHz. Deployable Helical Antenna for Nano-Satellites Currently small satellite, high gain, deployable antenna options are limited to a relatively few number of proven designs. Table 1 provides several examples of currently available small spacecraft deployable antennae. MECHANICAL DESIGN The helical structure was developed in response to the a requirement for a high gain UHF antenna capable of Directional antenna - Wikipedia A directional antenna or beam antenna is an antenna which radiates or receives greater power in specific directions allowing increased performance and reduced interference from unwanted sources. Directional antennas provide increased performance over dipole antennas—or omnidirectional antennas in general—when greater concentration of radiation in a certain direction is desired.
