In this work, a switchable bandstop filter is used as a decoupling structure for developing a miniaturized reconfigurable multiple input multiple output (MIMO) antenna. Initially, a dual band ((2.43-2.60 GHz and 3.51-3.79 GHz)) single monopole antenna structure is developed on FR4 substrate. Then the single monopole antenna and its replica are acco...

This manuscript proposes an Ultra-Wide band (UWB) Filtering Antenna (Filtenna) with application-based notches at Wi-MAX (3.3–3.7 GHz), WLAN (5.15–5.875 GHz), and ITU (7.725–8.275 GHz) bands. Initially, a monopole antenna is designed. To enhance bandwidth and bring about impedance matching, its ground plane is modified by introducing a triangular sha...

This manuscript proposes a triple band filtering antenna operating in the frequency range of 2.4 to 2.484 GHz, 4.2 to 4.5 GHz, and 5.15 to 5.825 GHz for possible application in WLAN and aeronautical radio navigation. Initially, a conventional square shaped monopole antenna is designed at 4 GHz, in which staircases are introduced at the edges to enh...

This manuscript proposes a Filtenna operating in the frequency range of 5.15-5.35 GHz for possible application in wireless local area network (WLAN). Initially, a monopole antenna consisting of a square loop radiating patch is designed at 5.2 GHz and is integrated into a bandpass filter (BPF) with centre frequency of 5.2 GHz. Within the proposed fr...

A new proposed circular disc monopole (CDM) antenna is designed for ultra-wideband (UWB) application. The dielectric substrate is used to print the antenna which is fed by 50 Ω CPW on the same substrate side. A stub is introduced across the feed line for improving the performances. In addition, the bandwidth (BW) is enhanced using modified ground p...

A new antenna structure comprising multiple radiating microstrip patches, representing a digital figure of eight, proximity fed by a microstrip line is proposed. On a double-layered substrate of FR4, this antenna achieves multi-band functionality in the range 3.2–13.51 GHz which covers IEEE 802.11a standard and other wireless communication systems....

A novel planar monopole antenna capable of multi-band operation is proposed. The proposed antenna has eight segment planar rectangular radiation patches placed on a baseline segment, fed by a CPW-feed. The proposed structures cover the useful bands such as IEEE 802.11 a, b, etc. Details of the proposed design along with the simulation and experimen...

A new antenna structure comprising of multiple radiating microstrip patches, representing a figure of digit eight, proximity fed by a microstrip line is proposed. On a double-layered substrate of FR4, this antenna achieves multiband functionality in the range of 3.81–12.42 GHz, which covers IEEE 802.11a standards and is suggestive of reconfigurabil...

The design of a triple-band planar monopole antenna is proposed. This antenna covers IEEE 802.11a, 802.11b, and 802.11g WLAN bands. Since the antenna is printed on a substrate, it can be easily integrated with the associated microstrip circuits lying on the same plane of the substrate. The antenna has been designed by using IE3D, a full wave MoM si...
