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

Sinuous antenna feed networkSinuous antenna is an antenna formed by rotating the curve given by (, Eq. (3)) about a central axis to generate the desired number of arms of the overall structure. The inner and outer radiuses of the antenna are usually defined by upper and lower frequencies. Split-beam mode four-arm slot sinuous antenna - IEEE Journals ... 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. Omnidirectional Circularly Polarized Antenna with High Gain ...
