DESIGN OPTIMIZATION OF A BOW-TIE ANTENNA FOR 2.45 GHz RFID READERS USING A HYBRID BSO-NM ALGORITHM

Design of koch fractal bow tie antenna for wireless applications

The crowding of wireless band has necessitated the development of multiband and wideband wireless antennas. Because of the self similar characteristics, fractal concepts have emerged as a design methodology for compact multiband antennas. A Koch-like fractal curve is proposed to transform ultra-wideband (UWB) bow-tie into so called Koch-like sided fractal bow-tie dipole. A small isosceles trian...

A Compact Modified Bow-Tie Antenna for High- Resolution GPR

A Planar Self-complementary Bow-tie Antenna for Uwb Applications

A new planar bow-tie antenna is proposed here for UWB applications. The self-complementary principle has been applied to a planar triangular monopole antenna along with bending the microstrip feed line. The antenna has a wider frequency band compared to the traditional bow-tie antenna, complies with the UWB requirements and it is directly matched to the (SMA) connector via 50Ω microstrip feed l...

Design of a Balun for a Bow Tie Antenna in Reconfigurable Ground Penetrating Radar Systems

This paper deals with the design of a reconfigurable antenna that resembles a monolithic UWB bow-tie antenna for Ground Penetrating Radar (GPR) applications. In particular, the attention is focussed on the design of the balun system able to work in the frequency band 0.3–1 GHz; the effectiveness of the design is shown by examining the behaviour of the scattering parameters S11 for both the refe...
