Kayani et al. proposed a simple, compact Vivaldi antenna in 2005. 11 Their single-sided design employed stripline-to slot-line coupling as shown in Fig. 4. The main advantage of this design is that the antenna can be made smaller compared to an antipodal Vivaldi antenna. A THz Slot Antenna Optimization Using Analytical Techniques In section 2, the antenna design is presented and the waveguide dimensions and the operation frequency are briefly discussed. First we describe a single slot on a rectangular waveguide and it is shown that it can be described using a model of a transmission line. By using Slots and Notch Loaded Rectangular Stacked Microstrip Antenna ... A quad-band circular slot antenna has been ... a stacked DGS microstrip antenna for multi-frequency operation is designed. ... The microstrip line feed is used to ... Chapter 8 Slot Antennas - 电子创新网
Slotted Rectangular Microstrip Patch Antenna for WiMax applications free download Abstract. In this paper a compact Rectangular Micro-strip Patch Antenna (RMPA) with single feed is presented. Resonant frequency of proposed antenna is shifted toward lower side by introducing rectangular slot...
24 cms AERIALS - videorepeater.co.uk ALFORD SLOT ANTENNA: 24 cms AERIALS. By M. Walters G3JVL. INTRODUCTION. The Alford Slot antenna, which has been developed for l.3GHz by G3JVL, is an easy means of obtaining an omni- directional radiation pattern with horizontal polarization . Dual‐frequency operation of a coplanar waveguide‐fed dual ... This paper proposes a novel dual‐frequency coplanar waveguide‐fed dual‐slot loop antenna. The two operating frequencies have the same polarization planes, and can easily be controlled by the perimeters of outer and inner rectangular‐slot loops in the proposed antenna. A Dual-Band Slot-Embedded Microstrip Antenna for Dual ... A Dual-Band Slot-Embedded Microstrip Antenna for Dual-Polarization Operation Muhammad Asad Rahman*, Eisuke Nishiyama, and Ichihiko Toyoda Abstract—In this study, a new slot embedded microstrip antenna for dual-band dual-polarization operation is proposed. The antenna comprises a single layer structure with a square radiating patch Analysis of U-slot loaded Patch for Dualband Operation

He told me that he called the tapered slot antenna a "Vivaldi" as it looked like the cross-section of an early trumpet. Vivaldi had written a trumpet concerto, and it was the 300th anniversary of Vivaldi’s birth in 1678.

A Dual-Band Slot-Embedded Microstrip Antenna for Dual-Polarization Operation Muhammad Asad Rahman*, Eisuke Nishiyama, and Ichihiko Toyoda Abstract—In this study, a new slot embedded microstrip antenna for dual-band dual-polarization operation is proposed. The antenna comprises a single layer structure with a square radiating patch Analysis of U-slot loaded Patch for Dualband Operation proposed to provide dual band operation such as radial slot antenna [3], rectangular microstrip slot antenna with a π-shaped slot [4], and hybrid dielectric resonator antenna [5]. The reactively loaded antenna is one of the popular techniques to obtain the dual band operation. Dual resonance is obtained by introducing the slots parallel to the N93-27751 Slot-line end-fire antennas for THz frequencies
