In this paper mutual coupling reduction between two elements of ultra-wide band (UWB) MIMO antenna by using a tilted SRR like structure with variable length is proposed. The antenna consists of two modified elliptical shaped monopole antennas designed using 0.787 mm thick RT duroid. Near field distribution of the antenna structure is studied to understand the isolation mechanism. Tilted variable length...
In this paper mutual coupling reduction in two element MIMO antenna structure using a SRR like structure with variable length is proposed. The structure consists of two modified elliptical shaped monopole antennas with the interelement spacing of 23 mm are fabricated using 0.787 mm thick RT Duroid substrate. S11 and S21 less than −10 dB and −18 dB respectively are obtained over 3.1–10.6 GHz. The proposed...
In this paper an antenna structure consisting of two high gain circular monopole antennas separated by a planar reflector for UWB repeater applications is proposed. The antennas are fabricated using 0.787 mm thick RT Duroid. The two antennas are placed on either side of a reflector of size 70 mm × 70 mm at a spacing of 12.5 mm. S11 and S21 < −10 dB and −32 dB are obtained over 3.2–10.6 GHz. Individual...
In this paper high gain parallel metal plated circular monopole UWB antenna with a planar reflector is proposed. The antenna is fabricated using 0.5 mm thick copper plate. Reflector of 50 mm × 60 mm is placed 10 mm below the antenna structure. VSWR = 2 and gain variation of 7.5–10.2 dBi are obtained over 4.1–10.6 GHz. The antenna offers unidirectional radiation patterns in both the planes with cross...
This article proposes a parallel metal‐plated tuning fork‐shaped omnidirectional antenna for UWB application.Printed monopole antennas fabricated on a substrate offer impedance band width, which can cover UWB. However, radiation pattern varies significantly over the bandwidth. The cross polar component increases with frequency and the pattern degrades from the desired omnidirectional characteristics...
