Trident-shape strip loaded dual band-notched UWB MIMO The stepped slot which is similar to the stepped slot proposed by Zheng et al. and Chao et al. , and a microstrip line with trident-shaped strip form an element of proposed MIMO antenna is depicted in Fig. 3(d). By proper tuning of the stepped slot dimensions and feed line position, broadband characteristics can be obtained. UWB MIMO Antenna with Band-Notched Characteristic Designing the ultra-wide same as S11 and S21, respectively, so we only show S11 and bandwidth for an UWB antenna is not such a problem and can S21 in Fig. 2 It can be seen that the simulated impedance be achieved through matching using etching a ground slot bandwidths (for S11 < −10 dB) of the antenna with and under the feed line, adjusting

A Broadband Pattern Diversity Annular Slot Antenna An annular slot antenna suitable for pattern diversity in wideband applications is presented. Pattern diversity is obtained by feeding the antenna simultaneously with two microstrip lines printed on the back of the substrate, which generate orthogonal radiation patterns. Four Ports Wideband Pattern Diversity MIMO Antenna Four Ports Wideband Pattern Diversity MIMO Antenna . Ramling P. Manurkar α & Veeresh G. Kasabegoudar σ. Abstract- In this paper a broadband four ports MIMO antenna with pattern diversity is presented. To obtain pattern diversity, four microstrip feeding lines are printed on one side of the substrate where as the modified ground plane is ...
In this paper, an UWB-MIMO antenna with frequency selective surface (FSS) decoupling structure is proposed. To realize antenna system miniaturization and integration, silicon material is applied as substrate. The proposed antenna becomes a very compact construction with dimension of 38.2 × 26.6 × 0.4 mm. The proposed broadband FSS unit consists of four split rectangles and one I-shaped strip. Draft Version A Reconfigurable Radiation Pattern Annular
