A Compact Frequency Selective Surface With Stable Response for WLAN Applications
Rajesh Natarajan,Malathi Kanagasabai,Sanjay Baisakhiya,Ramprabhu Sivasamy,Sandeep Kumar Palaniswamy,Jayaram Kizhekke Pakkathillam +5 more
TL;DR: In this paper, a compact frequency selective surface (FSS) composed of a modified swastika unit cell having the smallest dimension of 7 × 7 mm2 is proposed, aimed at the rejection of 5 GHz WLAN band.
Journal ArticleDOI
A Compact Antipodal Vivaldi Antenna for UWB Applications
TL;DR: In this paper, a compact antipodal Vivaldi antenna (AVA) with the dimension of $42 \times 36 \times 1.6~\hbox{mm}{^3}$ is proposed.
Journal ArticleDOI
Triband Antenna Structures for RFID Systems Deploying Fractal Geometry
Chitra Varadhan,Jayaram Kizhekke Pakkathillam,Malathi Kanagasabai,Ramprabhu Sivasamy,Rajesh Natarajan,Sandeep Kumar Palaniswamy +5 more
TL;DR: Two triband RFID antennas are proposed, one for the radio frequency identification (RFID) reader and the other for the RFID tag, each operating at 3.6, 5.8, and 8.2 GHz.
Journal ArticleDOI
Compact Monopole Antenna Backed With Fork-Slotted EBG for Wearable Applications
Padmathilagam Sambandam,Malathi Kanagasabai,Shini Ramadoss,Rajesh Natarajan,M. Gulam Nabi Alsath,Shanmathi Shanmuganathan,M. Sindhadevi,Sandeep Kumar Palaniswamy +7 more
TL;DR: In this article, a low-profile ultrawideband directional antenna for a wireless body area network (WBAN) is designed using a monopole backed with an electromagnetic bandgap structure, which acts as a reflector.
Journal ArticleDOI
