A novel compact triple elliptical monopole antenna has been designed, analyzed and fabricated for super wideband applications. To enhance the impedance bandwidth, author proposed a with patch excited by 50Ω triangular tapered microstrip feedline. Further improvement is achieved optimally modifying Defected Ground Structure (DGS) of antenna. The structure mounted on Roger’s RT-Duro...

An Antenna is a metallic structure that transmits and receives radio waves. Antennas come in all shapes sizes from tiny microstrip antenna for biomedical applications to very big parabolic reflector antennas satellite communications. A Super Wideband Square Monopole designed on Arlon AD260A FR4 Epoxy with CPW-feed structure. Notched bands are obtained by embedding inverted E-shaped stub, using ...

To reduce interference from other wireless communications, a compact super wideband frequency diversity hexagonal shaped monopole antenna with switchable rejection band capabilities is proposed. The patch consists of structure an open-ended horizontal slot that divides the into upper and lower parts. overall size proposed 36 mm <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmln...

A new method is developed for the Direction of Arrival (DOA) estimation wideband sources by refining initial estimates and posing super-resolution theory in a non-convex optimization problem. gradient-projection conducted accurate DOAs. The proposed can be performed any non-uniform linear array with no need focusing matrices. Moreover, greedy search algorithm employed to obtain implementation. ...

This paper presents a patch loaded slot antenna for super wideband (SWB) application. To obtain SWB characteristic, the proposed geometry combined rectangular and an overlying excited by trident shaped microstrip feed. It is observed that hybrid nature of effectively enhances impedance bandwidth up to 120%, combining resonance both slot. Besides, it investigated after converting conventional ta...

A new wideband Wilkinson Power Divider which use the nonuniform substrate integrated waveguide (NSIW) method is presented in this paper. This structure utilizes NSIWs instead of the uniform quarter wavelength SIWs in conventional Wilkinson power divider. The proposed structure is analyzed by odd and even mode analysis. The proper NSIW section widths can be extracted by using even mode while the...
