Excitation of metal casing using bent and folded dipole antenna with three conductors

چکیده
The antennas installed in mobile devices are small and low-profile compared to wavelength at the operating frequency. In general, horizontal elements short monopole have low radiation resistance. Low resistance requires matching circuit between 50 Ω feed line decreases efficiency. By using characteristic mode, excitation of ground plane improve has been investigated. This paper proposes structure with modified folded dipole antenna, which is placed close metal casing. surface current on casing excited by antenna contributes radiation.

We have modeled and simulate asymmetric microstrip folded dipole antenna on substrate materials and study the antenna performances. The conventional wire dipole antenna configurations are converted into corresponding microstrip version. The complementary nature of parallel coplanar strip line and waveguide models have been used to model the dipole antenna. The transmission line parameters namel...
متن کاملA Folded Dipole Antenna for Terahertz Continuous-wave Power Enhancement
Folded dipole antennas are analyzed to increase the terahertz continuous-wave output power. The calculated input impedance of the folded dipole antenna was 3000 Ω. In order to verify the power increase of the proposed antenna, the antenna is fabricated and measured by using the liquid helium cooled silicon bolometer.
متن کاملFundamental characteristics of a planar folded dipole antenna with a feed line on the dielectric substrate
Recently, the many services for the cellular phone are spread. Therefore, the broadband antenna for handsets is required. In our previous paper [1], the planar folded dipole antenna (PFDA) with a feed line, which consists of two parallel lines has been introduced and its characteristics have been analyzed. As a result, it was found that PFDA with a feed line had a broadband characteristic and t...
متن کاملFolded dipole plasmonic resonators.
A class of folded ordered plasmonic dipole nanoresonators based on insulator-metal-insulator (IMI) slab waveguides is proposed and studied. This work is motivated by the development of a novel fabrication process that avoids the need for direct write nanolithography and instead relies on accessible UV lithography and other top-down parallel fabrication techniques that result in metallic dolmen ...
