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). A new approach for feeding sinuous antenna - ScienceDirect 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 Design of an Ultra-Wideband Spiral Antenna for Ground

Slot Microstrip Antenna for 2.4GHz RFID Reader Application observed gain and directivity are 4.5dB and 5db respectively. By using the strip and slot, the proposed antenna deals properly with frequency shift for real application when embedded inside a handheld reader. V. CONCLUSION Thus the slot microstrip antenna was designed.The antenna shows good performance at 2.4GHz. Directional, High Gain - ARA, Inc. – Antenna Research

High Gain Compact Strip and Slot UWB Sinuous Antennas PDF | 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 ... Split-Beam Mode Four-Arm Slot Sinuous Antenna | Request PDF Request PDF on ResearchGate | Split-Beam Mode Four-Arm Slot Sinuous Antenna | A coplanar waveguide (CPW) center-fed four-arm slot sinuous antenna is introduced in this letter. The antenna ... Sinuous Antennas | High Gain Sinuous Antennas | Steatite The Steatite family of sinuous antennas simultaneously handle signals of any two orthogonal linear polarisations and simultaneous left and right-handed circular polarisations dependent on antenna design.. This provides intercept opportunities for a wide range of arbitrarily polarised signals, from devices also giving a wide bandwidth and broad beamwidth. Elson Agastra - Academia.edu

High Gain Compact Strip and Slot UWB Sinuous Antennas

In this paper, a directive sinuous slot antenna for Ultra Wideband (UWB) applications is presented. This antenna is feeding by a microstrip taper balun, which can be used as a coaxial line to Lecher line transition. To obtain directive antenna a reflector has been added and optimized. Understanding antenna gain – RCExplorer A common misprecepion is that a higher gain antenna is simply more effective than a low gain one; this is not true. First of we need to understand what the dBi value of an antenna means: “The decibel (dB) is a logarithmic unit of measurement that expresses the magnitude of a physical quantity (usually... 10 Best High Gain Antennas For WiFi Router | Wonderful… 4.
