It is a symmetric structure with two transmission lines and one resistor of 100Ω connecting the two transmission lines. The micro-strip medium here has both top and bottom layers to create broadband configuration using defected ground plane structure (DGS). The bottom layer is of floating conductor so to achieve selective bandwidths. The isolation between the paths is more than 10dB with better return loss along the band of 2GHz to 5GHz. The simulation of the proposed structure is done by using Ansys HFSS 19.0. A prototype has been made and the results are verified against the full wave simulations and it is observed that they maintain good agreement between the results. Key Words: Microstrip, broadband, Defected Ground Plane Structure (DGS), floating conductor, isolation 1. INTRODUCTION Emerging applications of microwave technologies and radio frequency demand for miniaturized broadband components that have multiple functionalities with high performance at low cost. Broadband Power dividers have applications in Microwave imaging systems, high data rate wireless communications, SDP, UWB, cognitive Radio etc. Broadband power dividers are used for signal distribution and signal tapping in different microwave communication & radio-frequency subsystems. These have different structures as reported in [1] – [12]. In [1] – [2], Lange couplers are used for designing the broadband power divider. Using Lange couplers give the advantage of broadband frequency, but due to critical issue of wire bonding it limits the highest frequency of operation. With the use of N stage transformers in [3] – [7] power dividers they operate in wide bandwidth. Multistage transformers though occupy more space; they are easy to design in realization. In [8], design of ultra wide power divider is done using non uniform directional couplers but this requires more space during implementation. Even though the 3db based couplers on left handed materials which offers broad bandwidth needs more space for their circuits [9]. In [10], with the help of short circuited stubs and coupled lines design ultrawide power divider for sharp role off and good isolation. From [11] we know that broad band coupler made us realize with the help of layer alignments and multilayer construction in electrical characteristics. 2. DESIGN APPROACH In this, the proposed power divider is designed over FR4 substrate. The design is on 40mmx16mm rectangular substrate. This is composed of one input port and two output ports along with 100Ω resistor connecting both the transmission lines. Next the floating conductor in the ground plane is designed with gap g, along with gap g that is between the rectangular patches.
