A low-profile antenna with multi-directional beam pattern using loop elements

A Low Profile Four-Way Directional Antenna with Dual Polarization

This paper presents a low profile dual polarized directional antenna composed of loop and dipole arrays mounted on a ground plane with each loops and dipoles being fed independently. Each loop antenna is paired with a reflector while each dipole antenna is paired with a director and a reflector. The proposed antenna is intended for an indoor base station (BS) with resonance frequency of 2.4 GHz...

A Planar Six-Sector Antenna using Loop Antenna with Detour Elements for WLAN Card Terminal

Development of A Compact and Low Profile ‎Cavity Backed Slot Antenna Using Microstrip ‎Gap Waveguide Technology

Proof of concept of a cavity backed slot antenna based on inverted microstrip gap ‎waveguide (IMGW) technology is presented. Since the antenna is operating based on the ‎first resonating mode of the cavity, it is more compact compared to the ordinary cavity ‎backed slot antennas in which the second cavity mode is used for radiation. Furthermore, ‎the proposed antenna element introduces lower lo...

Directional Antenna Beam Controlling Method using Fuzzy Logic System

This paper is an effective method to search or a quick scan the easy spot for directional antenna beams, and it is used for high speed data transmission in millimeter wave. The present paper proposes a method using the Fuzzy Logic control system for giving maximum data rate transfer using directional antenna[1]. The methods of transmission is using TDD, and it sends the control instructions of ...

Planar Directional Beam Antenna Design for Beam Switching System Applications

In this paper, a planar directional beam-switchable antenna with four orthogonal beam directions is proposed. The proposed antenna is designed with two crossed active elements and two parasitic elements for each direction. The design methodology is described on the basis of the Yagi-Uda method for the active and parasitic elements, respectively. By adjusting the effective electric lengths of th...
