FilipovicSplit-beam mode four-arm slot sinuous antenna.
Antenna gain. Antenna gain is often quoted with respect to a hypothetical antenna that radiates equally in all directions, an isotropic radiator. This gain, when measured in decibels, is called dBi. Conservation of energy dictates that high gain antennas must have narrow beams.
Slot Antenna Images - gveasia.com A parameter discussion of .. Navigation High Gain Compact Strip and Slot UWB Sinuous Antennas - Hindawi. Red Lion Casino Express. A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots .. The shape and size of the slot, as well as the driving frequency, determine the radiation pattern. Slot Antenna - an overview | ScienceDirect Topics Unlike the waveguide slot antenna that is excited from one side, the planar slot antenna demonstrates bidirectional radiation, which limits the application of this antenna. Alternatively, the slot may be either cavity- or reflector-backed to eliminate backside radiation at the cost of additional bulk and complexity. Split-beam mode four-arm slot sinuous antenna - IEEE ... 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.
Vivaldi antennas, which cannot be easily extended to polarization-agile applications. The sinuous antenna is both radiation efficient and can be used with polarization agility in its 4 arms version without excessive complications. However, conventional two-arms sinuous antennas do present a linear polarization which oscillates in frequency.
The gain of the sinuous slot antenna with reflector is increased from 4.6 to 9.5 dB between 4 GHz and 9.6 GHz. Ke Gong, Zhi Ning Chen, Xianming Qing, Peng Chen, … 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 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. Design of an Ultra-Wideband Spiral Antenna for Ground Design of an Ultra-Wideband Spiral Antenna for Ground-Penetrating Microwave Impulse Radar Applications Bradley Hutchinson Radar systems that allow early detection of underground IEDs can save lives.

Gain-intensified slot antennas backed by SIW cavity using… Gain-Enhanced SIW Cavity-Backed Slot Antenna with Arbitrary Levels of Inclined Polarization.In this paper, a gain-increased method of cavity-backed slot antennas based on excitation of high-order substrate-integrated waveguide cavity resonance has been proposed. 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. Simulated gain patterns of the SIW cavity-backed slot … High-gain antennas have various applications such as in satellite platforms, radar systems, routers, and repeater systems.In this paper, we propose a novel enhanced-gain planar slot antenna backed by an SIW cavity for 2.4 GHz wireless local area network (WLAN) applications.
