The researchers followed a regimented, five-step design procedure to create the antenna. Slots in the ground plane were introduced as all antenna design parameters were kept constant by making modifications in the microstrip feed lines with the changes in the ground plane. Basic Antenna Theory - Wireless connected to one side of the slot, and the outside conductor of the cable - to the other side of the slot. – The slot length is some (λ/2) for the slot antenna and (λ/4) long for the INF antenna. • The INF and the slot antennas behave similarly. • The slot antenna can be considered as a loaded version of the INF antenna. Microstrip Antennas – Part 2 - McMaster University (Transmission-line model. Design procedure for a rectangular patch. Cavity model for a rectangular patch.) 1. Transmission Line Model – The Rectangular Patch The TL model is the simplest of all, representing the rectangular patch as a parallel-plate transmission line connecting two radiating slots (apertures), each of width W and height h
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.
Design step for making slot antenna in HFSS Geometry of Slot Antenna Set Units: Select the units' inches.4. 4 | Antenna Output Parameter Conclusion: From this practical performed on HFSS software for Slot Antenna we obtained different output parameters of antenna , its return loss graph and far field pattern . 2.1 Design of the Wide Slot Antenna Following this procedure, a slot antenna is designed in the frequency band of 5-8 GHz for the purpose of gain enhancement over the entire operating band. Length of the slot determines the first resonating frequency and these slots radiate like a half wave dipole whose length is half of the... Design & parametric study of rectangular slot microstrip… ANTENNA STRUCTURE AND DESIGN The three essential parameters for the design of a rectangular microstrip patch antenna are: Frequency of operation ( 0ffrom the fig (c) and table 4, which shows that the variation of slot length L1 and slot width W1 effect bandwidth and return loss of the antenna. Design of L Slot Loaded Rectangular Microstrip Patch …

because one side is either completely enclosed, e.g., the slotted cylinder antenna, or it is desired that the radiation on one side be minimized. In these cases, the influence of the enclosed cavity region on the excitation and impedance of the slot antenna is significant to the antenna design. 8.2 SLOTTED-WAVEGUIDE ANTENNAS
A printed microstrip-line-fed slot antenna with a pair of parasitic patches for bandwidth enhancement is proposed in this letter. By using the parasitic patches along the microstrip feed line, an ... ATSC3.0 Ready Slot Antenna Design Using Advanced Antenna ... ATSC3.0 Ready Slot Antenna Design Using Advanced Antenna Optimization Methods Brandon George, Nick Wymant Radio Frequency Systems (RFS), Meriden, CT 06450 Coaxial slot antennas are a favored design by U.S. broadcasters due to their low complexity and ability to be customized [1]. Coaxial slot antennas currently designed and manufactured for the Wideband Bow-Tie Slot Antennas with Tapered Tuning Stubs (CPW) is investigated. The design was realized using a tapered metal stub introduced in the middle of the bow-tie slot. The modified structure shows wider bandwidth over the conventional bow-tie slot antenna. Parametric study of this new antenna results in a design procedure that helps design this class of antennas
Abstract: A design procedure for a wideband planar unidirectional antenna is presented based on the monopole slot antenna. Owing to the additional capacitance contributed by a stub-protruded feedline and two symmetrical stubs at the slot edge, the impedance-matching condition is improved; meanwhile, the resonance frequency of the monopole slot antenna is significantly shifted down, and an Design of Slotted Waveguide Antennas with Low Sidelobes
