Design of slots: the design of the slots depends on the phase and amplitude at the apertures. All the prototypes are designed for uniform amplitude and phase, although similar procedure can be used for other excitations. - The radial distance between radiation elements (two slots) is one wavelength.

Antenna parameters examined in this study include the dimensions and locations. of the substrates, feed line, ground plane coupling slot… Design of a Microstrip Monopole Slot Antenna With 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 The design of a resonant SWA is generally based on the procedure described by Stevenson and Elliot [4,6–9], by which the waveguide end is short-circuited at a distance of a quarter-guide wavelength from the center of the last slot, and the inter-slot distance is one-half the guide wavelength.

This paper presents the design and simulation of a compact rectangular slot patch antenna for dual frequency operation at 2.4 GHz and 5.2 GHz using the inset feed technique. The simulation of the designed antenna was done with the aid of computer simulation technology (CST) microwave studio version 12.

Compact Two-Layer Slot Array Antenna with SIW for 60GHz Design Procedure Design procedure of waveguide slot arrays was presented by Elliott in [4,5]. In first step, we must develop a model for the shunt admittance of a longitudinal slot in terms of frequency, slot length, and slot offset from the waveguide axis. To do this, a single slot was simulated in Ansoft HFSS for a range of lengths, offsets Design of Slot Antenna for Wideband Applications - ERNET
