A printed Bow-Tie slot antenna with loaded stub is proposed and the effects of changing the dimensions of the slot area, the stub and load sizes are considered in this paper. These parameters have a considerable effect on the antenna characteristics as well as its performance. An in-depth parametric study of these dimensions is presented. This paper proposes the necessary conditions for initial...

Finite-difference time-domain simulation results in bow-tie InGaAs diodes are presented. Dependences of electric field amplitude on frequency were investigated for various device shapes and sizes. It was shown that two metallized parts of the bow-tie type detector act as the separate antennas causing thus the experimentally observed fast sensitivity reduction at 1.63, 1.83, and 2.51 THz frequen...

A comprehensive study of electromagnetic waves underwater propagation for a wireless sensor network is introduced in this paper. A mathematical model for the path loss due to attenuation of electromagnetic waves propagates in sea and pure water is given. Reflection from the air-water and water-sand interfaces as a function of distance between sensors and water depth is also introduced. A high g...

To allow fast communication—at several Gb/s—of multimedia content among processors and memories in a multi-processor system-on-chip, a new approach is emerging in literature: Wireless Network-on-Chip (WiNoC). With reference to this scenario, this paper presents the design of the key element of the WiNoC: the antenna. Specifically, a bow-tie antenna is proposed, which operates at mm-waves and ca...

The paper describes the design and the experimental verification of three types of wideband antennas. Attention is turned to the bow-tie antenna, the Vivaldi antenna and the spiral antenna designed for the operation at millimeter waves. Bandwidth, input impedance, gain, and directivity pattern are the investigated parameters. Antennas are compared considering computer simulations in CST Microwa...

In this paper, we propose a paper-based pattern switchable antenna system using inkjet-printing technology for bi-direction sensor applications. The proposed antenna system is composed of two directional bow-tie antennas and a switching network. The switching network consists of a single-pole-double-throw (SPDT) switch and a balun element. A double-sided parallel-strip line (DSPSL) is employed ...

Abstract: In this paper a novel radial stub feeding microstrip bow-tie antenna is designed to operate between C and X band and its performance characterization is presented. This antenna is having simple structure and topology over other stub loaded antennas. In addition the proposed antenna adjusts to the desired frequency easily. Antenna output parameters like radiation pattern, axial ratio, ...
