The flgure indicates high antenna 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.
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).
Sinuous antenna has gradually replaced helical antenna in many applications such as the microwave guiderThe advantages of the new structure antenna are that the gain and the front and back ratio of radiationNovel UWB low-profile sinuous slot antenna[C]. Antennas and Propagation (EUCAP)... Directional antenna - Wikipedia A high-gain antenna (HGA) is a directional antenna with a focused, narrow radiowave beam width.When transmitting, a high-gain antenna allows more of the transmitted power to be sent in the direction of the receiver, increasing the received signal strength. A Wideband and High Gain Microstrip Four-slot Antenna… A microstrip antenna has been developed to meet this requirement. Microstrip antennas offer a conformal structure, low cost and ease of integration withA numerical simulation and an experimental implementation of a cross-shaped, microstripline-fed, printed, four-element slot antenna array are...

AIRLINK® relays information around the Earth using high-gain antenna systems and flies on nearly every commercial airline in the world. Low Profile Sinuous Slot Antenna for UWB Sensor Networks This article describes the design and implementation of a low-profile sinuous slot antenna, intended for ultra-wideband (UWB) sensor networks, which can be produced on one conductive layer. The article explains the design and optimization of the sinuous slot antenna and its modifications, including its sinusoidal curve shape. Other modifications were aimed at optimizing the antenna feeding. Omnidirectional Circularly Polarized Antenna with High ... A novel omnidirectional circularly polarized (CP) slot array antenna with high gain is proposed, which is based on the coaxial cylinder structure, and the orthogonal slots radiated the circular polarization wave around the cylinder. Further, the improved dual circularly polarized (CP) omnidirectional antenna based on slot array in coaxial cylinder structure is presented too, and two ports are ...

High-gain Millimeter-wave Planar Array Antennas with Traveling-wave Excitation Kunio Sakakibara Nagoya Institute of Technology Japan 1. Introduction High-gain and large-aperture antennas with fi xed beams are required to achieve high S/N ratio for point-to-point high-speed data-communication systems in the millimeter-wave band. 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). Non-Resonant Slotted Waveguide Antenna Design Method High Frequency Design ANTENNA DESIGN I n this paper a non-resonant slotted waveguide antenna design method is present-ed. The internal and external mutual coupling between adjacent radiat-ing slots is considered in the described meth-od. In order to confirm the usefulness of this method, a non-resonant waveguide array Directional antenna - Wikipedia
