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. 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 A novel approach for miniaturization of slot antennas A similar approach can be applied to design a meander type slot antenna [8]. In order to in- crease the efficiency of these antennas by reducing dissipation, the use of a high temperature superconductor (HTS) has been proposed [9], [10].

Design procedure of a U-slot patch antenna array for 60 ... Design procedure of a U-slot patch antenna array for 60 GHz MIMO application Abstract: In this paper, we present an antenna array with beam steering capability to characterize MIMO channels over 57-63 GHz frequency band. This uniform linear array is built of six U-slot patch elements which are spaced half wavelength to maximize the beam ... 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.

In section we present the design procedure and the simulated results of the corresponding section. The commercially available 3D electromagnetic solver HFSS [2] is used to simulation. Design of Slotted Waveguide Array Antenna Printed Wide Slot Ultra-Wideband Antenna - InTech - Open within the entire UWB. The design of a printed wide-slot antenna with a rotated slot is pre‐ sented in [20]. The impedance bandwidth of the antenna varies with the rotation angle of the slot and can maintain 50.2% with suitable angle. More recently, the design of a printed wide-slot antenna for wideband applications is proposed in [21].

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
