A Broadband Printed Bow-tie Antenna with a Simplified Balanced Feed

چکیده
A broadband printed bow-tie antenna with a simplified balanced feeding network and modified tapering is presented. Microstrip and parallel-strip transmission lines printed on the substrate with high dielectric permittivity realize the proposed feeding network. The ground-plane transition between the microstrip line and the parallel-strip line is exponentially tapered so as to reduce the reflection losses and produce a balanced feed for the antenna. This printed bow-tie antenna achieves a 68% measured bandwidth and a stable radiation pattern within the X-band. Commercial FEM software is used for optimization of the bow-tie antenna and the simulation results agree very well with the experiment. © 2005 Wiley Periodicals, Inc.

Design and Implementation of a Compact Super-Wideband Printed Antipodal Antenna Using Fractal Elements
A compact printed fractal antipodal bow-tie antenna is designed and implemented to simultaneously cover the operations in the C, X, and Ku-bands. It is demonstrated that by addition of small fractal elements at the sides of hexagonal arms of the bow-tie, a wide operating frequency range of 3.3 to 19.1 GHz can be covered while antenna size is only 30×34×1.2 mm3. In order to match the antenna to ...
متن کاملUWB 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...

This paper presents a broadband and compact planar quasi-Yagi antenna for multi-band 3G/4G applications. The proposed quasi-Yagi antenna consists of a modified bow-tie driver to increase the bandwidth, a passive reflector and two passive directors to enhance the directivity at the lower and higher ends of the operating band, respectively. A microstrip-to-slotline transition feed is used to achi...
متن کاملA Study on Miniaturization of Bow-Tie Antenna with Folded Elements
Bow-tie antenna is one of wideband antennas [1]. It has been reported that the bow-tie antenna has been miniaturized by adding folded elements [2]. In this paper, it is shown that bending the bow-tie antenna with folded elements is effective method for miniaturization. The bent bow-tie antenna with folded elements can be more miniaturized than conventional bow-tie antenna with folded elements, ...

A micro strip-fed printed bow-tie antenna is presented inorder to achieve wide bandwidth, high gain, and size reduction. A comparisonbetween the bow-tie and the quasi-Yagi (dipole and director)antennas shows that the bow-tie antenna has a wider bandwidth, highergain, lower front-to-back ratio, lower crosspolarization level, andsmaller size. Two-element arrays are designed and their characterist...
