controlling slot excitation, by adjusting the slot offset from the center line of the waveguide. Prior to the design of an array it is required to determine the resonant slot length, equivalent circuit and variation of the circuit parameters with the change in offset values. S-parameters of the slotted waveguide are computed for this purpose. 2.
A slotted waveguide has no reflector but emits directly through the slots. The spacing of the slots is critical and is a multiple of the wavelength used for transmission and reception. The effect of this geometry is to form a high gain antenna that is highly directional in the plane of the antenna. SIW Based Slot Antenna In X-Band Using Rogers/RT duroid 5880 ...

A waveguide array antenna is composed from a number of open waveguides lying in one plane on the radiation side, of which a part is fed on the reverse side thereof, while the other ones are closed off. Substrate Integrated Waveguide Antennas | SpringerLink The scanning angle is three times in SIW compared to the hollow waveguide. In Cao et al. planar beam scanning substrate integrated waveguide (SIW) slot leaky-wave antenna (LWA) is proposed for enhancing scanning range and gain flatness using a modified composite right/left-handed transmission line (CRLH TL) structure. Tunable slot antenna backed by substrate integrated waveguide ... diode in an interdigital slot. This antenna has a tuning range of 370 MHz. An electronically tunable antenna designed by applying the half mode SIW was studied in Ref. 10. The res-onant frequency was varied from 2.99 to 3.59 GHz. The purpose of this work is to design a cavity backed slot antenna based on the SIW technology with a simple
Slot Antenna. Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide.
Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications.
