[Paper] Low Profile UWB Frequency Selective Surface based Antenna

New UWB Shielding with Frequency Selective Surfaces

In this paper a Frequency Selective Surface (FSS) as a UWB electromagnetic shield is introduced. The proposed FSS comprises a quasi-J.C-Jerusalem Cross- and a copper ring, which are located at both sides of a FR4 substrate and can represent a S.E -Shielding Effectiveness- better than 20dB in 90% bandwidth of Ultra Wide Band frequency. This structure is compact and thin. Each cell comprises J.C ...

Low-cost, compact UWB antenna with frequency band- notch function

Low-cost, compact, circular planar dipole UWB antennas have been designed, based on the ‘two-penny dipole’. One of the dipole arms has been integrated with the ground plane of a microstrip transmission line, the strip being connected to the other dipole arm. The use of microstrip in stead of stripline technology hardly degrades the radiation characteristics, but simplifies the antenna architect...

Angular-Stability Low-Profile Miniaturized Frequency Selective Surface Based on Complementary Structure

A new architecture for a low-profile miniaturized-element frequency selective surface based on complementary structure capable of providing a high angular stable performance is proposed. The proposed FSS is composed of an array of convoluted cross dipoles and its complementary slots pattern that is separated by a thin dielectric substrate. An equivalent circuit model for this FSS is presented t...

A Very Compact and Low Profile UWB Planar Antenna with WLAN Band Rejection

A low-cost coplanar waveguide fed compact ultrawideband (UWB) antenna with band rejection characteristics for wireless local area network (WLAN) is proposed. The notch band characteristic is achieved by etching half wavelength C-shaped annular ring slot in the radiating patch. By properly choosing the radius and position of the slot, the notch band can be adjusted and controlled. With an overal...
