This letter presents an eight-port, multiple-polarization, ultrawideband (UWB) diversity antenna array. The unit-cell antenna is constructed from a basic square monopole antenna. With suitable modifications in the radiating plane and the ground plane, the unit-cell antenna is designed to operate between 2.9–12 GHz to cover the entire UWB range. The designed UWB radiator is then replicated within a...
A novel ultra-wideband (UWB) equal power divider using rectangular rings of different impedances on microstrip line is proposed in this paper. It is demonstrated that 3 dB powers splitting from one input port to two output ports is achieved. In addition, good impedance matching at all the three ports and excellent isolation between two output ports are obtained over the specified 3.1–10.6 GHz UWB...
A novel quad-band unequal power divider with coupled line section using stepped-impedance transformers is presented in this paper. Coupled lines section is used to achieve the necessary impedance transformation at four selected frequencies. The topology of the structure, different from conventional Wilkinson power divider, is the coupled lines instead of the transmission lines. In this paper the structure...
A novel Dual band equal power divider with coupled line section using stepped-impedance transformers is presented in this paper. Coupled lines section is used to achieve the necessary impedance transformation at two selected frequencies. The topology of the structure, different from conventional Wilkinson power divider, is the couple lines instead of the transmission lines. In this paper the structure...
A novel RF power divider for CDMA (1.8GHz), Bluetooth (2.4GHz) & 3G (2.1GHz & 2.5GHz) application using stepped-impedance technology on microstrip line is proposed in this paper. This divider is formed by installing the concept of a microstrip multi-section impedance transformer and for achieving of wideband using stub matching. Finally, a compact power divider is designed, and it is demonstrated...
A novel Tri-Band equal power divider with coupled line section is presented in this paper. Coupled lines section is used to achieve the necessary impedance transformation at three selected frequencies. The topology of the structure, different from conventional Wilkinson power divider, is the coupled lines instead of the transmission lines. The most important and unique method is used here in this...
High power ultra wideband (UWB) systems can be used for various applications like buried target detection, electrical characterization of materials, space debris detection and as a source for vulnerability studies on electronic circuits. A high power UWB radiator system is developed at BARC, Mumbai. This is a 120 kV, 66 Ohm system which can generate intense electromagnetic fields. Any UWB system consists...
