J-pole antenna - Wikipedia The J-pole antenna, more properly known as the J antenna, [1] was first invented by Hans Beggerow in 1909 for use in Zeppelin airships. [2] Trailed behind the airship, it consisted of a single element, one half wavelength long radiator with … Dual-band blade antenna - Wikipedia Dual-Band Blade Antenna, a type of commercial RF "Blade antenna" that uses a "plane and slot design" to get efficient omni-directional coverage at two distinctly different RF bands.
In the field of antenna design the term radiation pattern (or antenna pattern or far-field pattern) refers to the directional (angular) dependence of the strength of the radio waves from the antenna or other source. Particularly in the fields of fiber optics, lasers, and integrated optics ...
A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. The shape and size of the slot, as well as the driving frequency, determine the radiation pattern.

How does a so-called slot antenna work? How can one construct one? What might be the radiation pattern and efficiency compared to a wire antenna? And, if a small slot ... ex W1GHZAntenna Book W1GHZAntenna BookW1GHZAntenna Book Microwave W1GHZW1GHZAntenna BookAntenna Book Microwave W1GHZ MicrowaveMicrowave 1 Antenna ... instance, a vertical slot has the same pattern as a horizontal dipole of the same dimensions — and we are able to calculate the radiation pattern of a dipole. Thus, a longitudinal slot in the broad wall of a waveguide radiates just like a dipole perpendicular to the slot. Antenna Theory - Slot - Tutorials Point Antenna Theory Slot - Learn Antenna Theory in simple and easy steps starting from basic to advanced concepts with examples including Fundamentals, Basic Parameters, Parameters, Near and Far Fields, Radiation Pattern, Isotropic Radiation, Beam and Polarization, Beam Width, Reciprocity, Poynting Vector, Types of Antennas, Wire, Half-Wave Dipole, Half-Wave Folded Dipole, Full-Wave Dipole, Short ... Slot Antenna Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear.
