Slot fed dipole antenna

A practical slot antenna is the cavity-backed slot antenna. Unfortunately, the equations related to the cavity backed slot antenna are somewhat complicated and in my opinion don't give a good idea of how they work. Hence, I'll present the basics, present some experimental results and try to give an idea of design parameters. A slot line fed planar dipole antenna with a parasitic strip for wide band applications is presented. The presented antenna offers a VSWR bandwidth from to GHz covering the DCS/PCS/UMTS and IEEE b/g bands with a gain better than REVIEWPOKER.INFO by: efficient radiator with an added advantage of having uniplanar nature. A slot line fed antenna on low permittivity substrate has been investigated which makes use of an open ended design that approximates it to a dipole [7]. In this communication, we present a simple uniplanar slot line fed antenna with moderate gain suitable for /

Antenna Theory - Slot

At these frequencies, the slot length is 0. More of a transmitter's current is dissipated as heat due to the finite resistance of the conductors which is greater than the radiation resistance. This method can be used to compute the radiation resistance for any antenna whose far field radiation pattern has been found in terms of a specific antenna current. The high feedpoint impedance R f. A dipole is omnidirectional in the plane perpendicular to the wire axis, with the radiation falling to zero on the axis off the ends of the antenna. They are usually constructed of two lengths of wire joined by a strain insulator in the center, which is the feedpoint.

Dipole antenna

Slot Antenna is an example of Aperture antenna. A rectangular slot is made on the conducting sheet. These slot antennas can be formed by simply making a cut on the surface, where they are mounted on. The use of slot antennas is well understood through its working principle. Let us have a look at the structure of a slot antenna. When an infinite conducting sheet is made a rectangular cut and the fields are excited in the aperture which is called as a slot , it is termed as Slot antenna.

This can be understood by observing the image of a slot antenna. The following image shows the model of a Slot antenna. This concept gives an introduction to the slot antennas. The above images clearly explain the principle. The light does not pass through the opaque area, but passes through the aperture. The light does not pass through the plane but through the remaining portion.

The screen is not placed to observe the resultant combination. The effect of screen gets nullified. This principle of optics is applied to electromagnetic waves for the wave to get radiated.

It is true that when a HF field exists across a narrow slot in a conducting plane, the energy is radiated. Consider an infinite plane conducting screen is taken and pierced with apertures of desired shape and size and this will be the screen of slot antenna. Another screen is considered interchanging the places of aperture and screen area which is the complementary screen.

Details

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. Often the radio waves are provided by a waveguide , and the antenna consists of slots in the waveguide.

Slot antennas are often used at UHF and microwave frequencies instead of line antennas when greater control of the radiation pattern is required. Slot antennas are widely used in radar antennas, particularly marine radar antennas on ships, for the sector antennas used for cell phone base stations , and are often found in standard desktop microwave sources used for research purposes. A slot antenna's main advantages are its size, design simplicity, and convenient adaptation to mass production using either waveguide or PC board technology.

Due to Babinet's principle a slot in a waveguide has the same radiation pattern as a driven rod antenna whose rod is the same shape as the slot. This can be used to determine the radiation pattern using calculations for a more conventional antenna. He invented it in order to produce a practical type of antenna for VHF television broadcasting that would have horizontal polarization, an omnidirectional horizontal radiation pattern and a narrow vertical radiation pattern.
