Design of Ultra-Wideband Tapered Slot Antenna by Using ... AbstractIn this paper, the tapered slot antenna (TSA) with corrugation is proposed for UWB applications. The multi-section binomial transformer is used to design taper profile of the proposed TSA that does not involve using time consuming optimization. A step-by-step procedure for synthesis of the step impedance values related with step slot widths of taper profile is presented. Design of a novel bandwidth-enhanced double-slot TSA and ... But the bandwidth of the gain more than 10 dB is only from 5 GHz to 15 GHz. In this paper, a modified tapered slot antenna with double-slot structure, is proposed. The radiation characteristics of the antenna are good. The fractional bandwidth reaches 167% from 2.5 GHz to 28 GHz.
Optimum performance is generally considered to be achieved Fig. 1 Schematic of Microwave Antenna with a –10 dB edge illumination taper.

Jam, "Optimum Design of Tapered Slot Antenna Profile," IEEE Transactions on Antennas & Propagation, vol. 51, No. 8, 2003... Optimum Design of Tapered Slot Antenna Profile - Semantic… A method for the design of slot-line tapers for Vivaldi antennas is presented. A stepped quarter-wave Chebychev transformer is first designed in slotline, and then a smooth curve is fit to the steps. The validity of the method is verified through measurements of experimental designs for the 1 to 3 GHz... Figure 1 Tapered Slot Antenna Types (a) Linearly Tapered…
Compact Vivaldi Antenna With Balun Feed For Uwb
Multicorrugated patterns are implemented to obtain better matching performance when the antenna feeds the GS lens with broadband coverage. An implemented design for grooving the lens profile presents a new principle to obtain an optimum focal point feed using the tapered slot antennas.
Optimum Design of Traveling-Wave SIW Slot Array Antennas
Endfire antenna elements of the tapered slot antenna (TSA) type can be employed both as single elements and in arrays. TSAs utilize a tapered slot in the metalization on a thin dielectric substrate, to radiate in the "end-fire" direction (along the tapered slot, see Figure 1). The special case of air dielectric also has been investigated. Stripline Fed Tapered Slot Antenna - atmsindia.org A tapered slot antenna uses a flared slot line etched on a dielectric substrate to produce an end-fire pattern from a surface wave. In this paper the development of a strip line fed tapered slot antenna has been presented. Relevant simulation and measurement results are also given. II. DESIGN OF THE 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]. Notch Antennas A notch antenna, also known as tapered slot antenna (TSA), is an end-fire traveling wave antenna. Like microstrip antennas, the TSA features low profile, light weight, easy fabrication by photo- etching, conformal installation and compatibility with microwave integrated circuits (MIC).

CHAPTER 2 DESIGN AND MODELING OF EXPONENTIALLY TAPERED ... profile of the slot. Of all the designs illustrated in Figure 2.1 [90], only the Vivaldi [91] and linearly tapered profile [78] have been thoroughly studied over the past few years. Planar tapered slot antennas have two common features. The radiating slot acts as the ground plane for the antenna and the antenna is fed by a balanced slot line. Compact Vivaldi Antenna With Balun Feed For Uwb For the 3.5–11.5 GHz operation, a tapered slot antenna with balun design was developed. The design parameters of the proposed LTSA are shown in Fig. 1. The top layer shows the micro strip line (indicated in red color) used for feeding the tapered slot antenna. The bottom layer indicates the linear taper profile which is Shahrokh Jam - Academia.edu Optimum design of tapered slot antenna profile more. by Shahrokh Jam. The optimum design of the tapered slot antenna (TSA) profile and geometry is achieved through its modeling by a stepline terminated in free space intrinsic impedance. The impedance matching of the TSA input impedance (obtained by the...
