procedures for linearly polarized waveguide slots. .... 1.2 Linearly Polarized Slots. ...... Concentric Array Radial Line Slot Antenna,” IEE Proc – Micro, Ant, and. Helical antenna - Wikipedia A helical antenna is an antenna consisting of one or more conducting wires wound in the form of a helix. In most cases, directional helical antennas are mounted over a ground plane, while omnidirectional designs may not be. The feed line is connected between the bottom of the helix and the ground ... For monofilar designs the radiation is linearly polarized parallel to the helix ... Radiation Properties of a Linearly Polarized Radial Line ... - J-Stage
A television antenna, or TV aerial, so that linearly polarized antennas can receive the signal equally well in any orientation. In the previous standard analog television, used before 2006, the VHF and UHF bands required separate tuners in the television receiver, which had separate antenna inputs.

Optimization of Beam-Tilted Linearly Polarized Radial-Line ... This letter investigates the performance of beam-tilting technique when applied to improve matching of linearly polarized radial-line slot-array antennas. The application of a full-wave analysis reveals a severe deterioration of radiation patterns even for small tilt angles. An iterative optimization procedure is proposed in order to restore the radiation performance in conjunction with the ...
