نویسندگان
چکیده
This paper presents a study on bow tie antenna with U-shape slot, designated for the Wireless applications. It is designed to work on a thick substrate (h = 1.6mm) with a high dielectric constant ( = 4.4) operating at three frequencies (2.4, 4 and 5GHz). Two U-shaped slots are introduced in the both sides of bow tie antenna in order to achieve a very low return loss at these frequencies. The antenna is simulated with HFSSv11 simulator. The proposed antenna can exhibit minimum return loss, Omni-directional radiation pattern, wide impedance bandwidth, VSWR<2, and the stronger current distribution throughout the antenna.

UWB Planar Conical Horn-Shaped Self-Complementary Bow-Tie Antenna
An ultra-wideband (UWB) self-complementary planar bow-tie antenna (SCPBTA) is proposed. The antenna consists of a printed conical horn-shaped (CHS) radiator and a counterpart CHS slot etched on a rectangular ground plane. The printed CHS radiator is connected directly to the 50Ω microstrip line by bending the end portion of the feed line. As a result, the antenna has a simple structure which do...

متن کاملA 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...
