Slot Antenna Images - International Journal of Antennas 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
INTRODUCTIONMicrostrip slot antennas are widely used for military and commer-cial applications due to their promising features such as lightweight, small sizeTherefore, a metallicreector or an enclosed cavity behind the slot should be used toreduce the back radiation and enhance the antenna gain.
Directional antenna - Wikipedia Directional antenna. A high-gain antenna ( HGA) is a directional antenna with a focused, narrow radiowave beam width. This narrow beam width allows more precise targeting of the radio signals. Most commonly referred to during space missions, these antennas are also in use all over Earth, most successfully in flat,... High Gain Compact Strip and Slot UWB Sinuous Antennas - CORE Abstract. 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. 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.

The sinuous l antenna element described here is one such element, suited to these kinds of applications. It is compact, has a good E- and H- planeA high bandwidth system therefore requires a wideband antenna. Additionally, the radiation pattern should be same at 7 Measurements were... Thèse | Chapter 2. Feeding Systems for Ultra Wideband …
Slot Antenna: Coupling RF energy into a slot in a large metallic plain can result in radiated energy with a pattern similar to a dipole antenna mounted over a reflection surface. The length of the slot is typically one-half wavelength.

Slot Antennas Source: ANTENNA ENGINEERING HANDBOOK. Chapter 8. Slot Antennas. William F. Croswell.The electric field is everywhere normal to the surface of the slot antenna except in the region of the slot itself.Note 1: Length of taper is proportional to gain; maximum gain approximately 10 dB. High-Gain Antenna (HGA) - Definition from Techopedia A high-gain antenna (HGA) is an antenna with a narrow radio beam that is used to increase signal strength. High-gain antennas provide a more precise way of targeting radio signals and are therefore very essential to long-range wireless networks. Radar Basics - Slot Antennas
