Compact Wideband Gysel Power Divider With Arbitrary Power Division Based on Patch Type Structure

Abstract

Abstract-A novel Gysel power divider based on patch type structure is presented in this paper. The proposed power divider possesses broad bandwidth, small physical occupation and arbitrary power division. More than 30% bandwidth enhancement is achieved based on the −15 dB input return loss criteria, while 55% size reduction is realized compared with conventional Gysel power divider. What's more, flat dividing is obtained in the design without using additional transmission line sections. Based on the novel structure, a design procedure of power dividers with unequal power division ratios is provided without using narrow microstrip line. To verify the design approach, the proposed power dividers with equal and unequal (2:1 and 4:1) power divisions at the centre frequency 1.5 GHz are fabricated and measured. The results demonstrate that the design can fulfil our goals.

An Improved Uwb Non-Coplanar Power Divider

“…As we know, the classical Wilkinson power divider [1] and its improved structures have been presented in the previous papers [2][3][4][5][6][7]. On the other hand, the other forms of power dividers with different design methodologies have been proposed [8][9][10][11][12]. The input and output ports of these power dividers are coplanar.…”

Design of an Ultra-Wideband Power Divider via the Coarse-Grained Parallel Micro-Genetic Algorithm

“…The power divider is one of the key passive components in the design of microwave circuits and antenna arrays, but due to the limitation on frequency bandwidth, which is not suitable for the UWB systems [3][4][5]. So wideband power dividers are needed.…”

A Design of Quasi-Arbitrary Phase Difference Unequal Microstrip Power Divider

“…With the development of radio frequency (RF) technology, the actual requirement for feeding networks is not only unequal power division, but also arbitrary phase difference [6]. Recently, extensive researches about power dividers have been focused on size reduction, high power division and dual-band applications [7][8][9]. However, the output arbitrary phase difference characteristic was rarely discussed, which limits its use.…”
