Two-element ultra-wideband (UWB) multiple input and multiple output (MIMO) antennas are presented to obtain high isolation. The designed UWB-MIMO antennas are composed of two identical orthogonal antenna elements, and a defected ground structure with I-shaped slot and a pair of L-shaped stub are employed to get better isolation. Bandwidth of the proposed antennas range from 3.28 GHz-12 GHz. Also,...
In this paper, an accurate equivalent circuit model is presented for a triple frequency rejection band UWB antenna that provides the desired frequency rejection function at center frequencies of 2.92 GHz, 4.06 GHz and 5.28 GHz. The extraction of the equivalent circuit model of the presented antenna mainly depends on the impedance characteristic of electromagnetic (EM) simulation. The equivalent circuit...
In this paper, a microstrip-fed multi-band antenna is proposed for wireless communication applications. The proposed multi-band characteristics are implemented by etching ratio period defected microstrip structures (RP-DMSs) into a 50Ω microstrip line to construct desired stop bands in a wide-band antenna. As a result, a multi-band antenna is realized for S-band, C-band and X-band communication systems...
This paper provides a printed anti-interference antenna with excellent wide tunable and reconfigurable multiple filtering bands for ultra-wideband applications. The anti-interference characteristics are realized by the use of stubs and resonators to filter out unwanted narrowband signal interferences. Also, the wide tunable filtering function is implemented by adjusting the dimensions of these designed...
An ultra-wideband (UWB) antenna with quad notch bands is presented by using two similar fork-shaped resonators (FSRs) settled aside the feed transmission line. The proposed antenna is printed on a substrate with a relative permittivity of ε4 = 2.65 and a loss tangent of δ = 0.001, and the designed antenna consists of a microstrip feed structure, a modified trapezoidal ground plane, a fan-shaped radiating...
