Double-plane pattern enhancement of rectangular slotted… Conventional slotted waveguide antennas are well known and prominently used for many military and even marketable applications. This is due to theirIt is also well known that this type of antennas is a typical array of slots with which the width of the main beam can be controlled in only one plane by... High Speed Circuits | Beam Steering Antennae ...Tapered Slot Antenna Planar antenna for continuous beam scanning and broadside radiationof Width-Modulated Microstrip Lines," IEEE Transactions on Antennas and Propagation, vol. 61Planar antenna for continuous beam scanning and broadside radiation by selective surface wave suppression. Implementation of rectangular slit-inserted ultra-wideband… In this paper, a tapered slot antenna capable of ultra-wideband communication was designed. In the proposed antenna, rectangular slits wereIn this paper, a tapered slot antenna is designed and proposed. The antenna has a 3 dB beam width, high gain, and directive characteristics, which are... A beam shaping reconfigurable radial line slot array...
The angular width of the beam radiated by high-gain antennas is measured by the half-power beam width (HPBW), which is the angular separation between the points on the antenna radiation pattern at which the power drops to one-half (-3 dB) its maximum value. For parabolic antennas, the HPBW θ is given by the formula show here. A parabolic ...
A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz. WIDE BEAM TAPERED SLOT ANTENNA FOR WIDE ANGLE SCANNING PHASED ...
