In this paper, a dual-band CPW-fed MIMO antenna is designed and analyzed. Fundamental resonance of the coplanar stepped impedance resonator (CSIR) produces the 1st operating band, while its harmonic resonance and the resonance of the rectangular slot line resonator (RSLR) construct the 2nd band. The port-to-port isolation within the 2nd band is high since it works at the harmonic resonant frequency...
A compact dual-band planar monopole antenna for 2.4/5GHz WLAN application is presented. The two resonant modes of the proposed antenna are associate with four slots which contribute to the upper resonant frequency and can reduce the size of the lower resonant length. The parametric study is performed to understand the characteristics of the proposed antenna. Experimental results show that the designed...
The High-power radial line helical circular array antenna is a novel antenna developed to realize directional radiation of high-power microwaves. This kind of antenna uses short helical antenna as its radiation element, and uses radial line as its feeding waveguide. New probes that can be fixed directly on the radial waveguide (without the need for medium support) are used to couple energy from the...
The design of an ultra wideband antenna (UWB) for communications and ground penetrating radar system presents challenges. There is often a desire for the antenna to be small while maintaining their UWB characteristics. This is especially the case in ground penetrating radar systems that need to fit into buried pipes. In this paper several antenna configurations are examined to meet these requirements...
