A couple microstrip antenna employing serrated coupling

A serrated microstrip lines Wilkinson power divider

“…The use of isolation stubs to reduce the parasitic effects in traditional Wilkinson power dividers [4]. On the other side, some researches show that ground plane serrations can as a nonintrusive method to improve the isolation and the radiation characteristicistics of the elements [5], and a coupled microstrip antenna employing serrated coupling to improve in the impedance characteristicistics for bandwidth enhancement [6], which are shown in Figure 1, respectively. In this paper, a novel millimeter-wave wideband Wilkinson divider using serrated microstrip lines is presented to obtain a good transfer performance in the range of interest band.…”

“…DIVIDER DESIGN In our work, a serrated microstrip line and a multiple cascading stage technique are used to enhance the bandwidth in wilkinson power divider design, which is depicted in Figure 2(a). Previous studies show that the use of ground plane edge serrations for microstrip patch antennas have demonstrated the isolation and the radiation characteristicistics improvements in the overall operation of the device [7], and a couple microstrip antenna employing serrated coulping results in the impedance characteristicistics of this bandwidth can be significantly improved [6]. A serrated microstrip line adopted in the wilkinson circuit due to it has a good impedance matching characteristicistic at the cost of ripples in the passband.…”

Transmission Line Model for an Edge-Coupled Patch Antenna

“…However, the patch usually operates around one resonance frequency of narrow bandwidth. Numerous studies have proposed ways to enhance patch antenna bandwidth and reduce antenna size by, for example, composing an impedance matching network with the antenna's structure through stacked geometry [3], employing coplanar geometry with a tuning stub [4], forming additional resonators with slots [5], designing an antenna with a thick substrate [6], and applying edge-coupled antenna topology (parallel [7] or serrate coupling [8]). Among these, edge-coupled patch antennas employing parallel and serrate coupling are of interest to us because of their compact design, wideband operation, and simple integration.…”

Compact Broadband Microstrip Antenna Using Two Semicircular Gap-Coupled Resonators

“…The serration of the coupled microstrip antenna is proposed for bandwidth enhancement. This antenna provides 30.5°0 bandwidth without increasing antenna size and manufacturing costs [9]. This paper presents a novel MSA which is consisting of a semicircular driven patch and another gap-coupled shorted semicircular parasitic patch.…”
