T-antenna - Wikipedia A T-antenna, T-aerial, flat-top antenna, or top-hat antenna is a capacitively loaded monopole wire radio antenna [1] used in the VLF, LF, MF and shortwave bands. [2] [3] [4] T-antennas are widely used as transmitting antennas for amateur … Omnidirectional antenna - Wikipedia Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so … US4792810A - Microwave antenna - Google Patents
A new type of linearly polarized Radial Line Slot Array (RLSA) antenna developed by FR-4 substrate is proposed for outdoor WLAN point to point application. The WLAN is based on the IEEE 802.1 la standard and the operating frequency range is the upper UNII band (5.725-5.875) GHz. The frequency range is use for point to point microwave link.
NOVEL DESIGN OF MULTI LAYER RADIAL LINE SLOT ARRAY ANTENNA ... Novel Design of Multi Layer Radial Line Slot Array Antenna 85 using FR-4 Susbstrate using Borland C++ 5.00. To achieve the desired radiation pattern in the slots surface design, some parameters in the input data file have to be changed according to the desired frequency, relative Characteristics of small-aperture, single-layered, radial ... A radial-line slot antenna (RLSA) is a high-efficiency planar array. A double-layered radial line and uniform slot length have been adopted in conventional RLSAs. A single-layered RLSA is much simpler in structure, but the slot length must be varied to synthesise uniform aperture illumination. A Concise Design of Large mm-Wave Radial Line Slot Antenna ...

A low profile slot antenna is provided which includes first and second oppositely disposed metallic plates with a dielectric layer disposed therebetween. An array of horizontal and vertical radiating elements are formed in the first … US3063049A - Linearly polarized monopulse lobing antenna having… The antenna axis is in the center of the radial waveguide 10 and extends directly out of the paper. For lobing to provide range information, the current excitations established by quadrants correspond to the vectorial components indicated by … US6297774B1 - Low cost high performance portable phased array… Each antenna element is preferably a dual polarization octagonal patch antenna element disposed on a common surface of the antenna aperture layer. Antenna (radio) - Wikipedia The end result is that the resonant antenna will efficiently feed a signal into the transmission line only when the source signal's frequency is close to that of the design frequency of the antenna, or one of the resonant multiples.
Abstract: A design for linearly polarized radial line slot antenna (RLSA) is proposed. A novel slot arrangement is presented which couples to the rotationally symmetric guided waves to produce a uniform aperture distribution with linear polarization. Basic characteristics were measured in the 12-GHz band on a model antenna.
