Journal ArticleDOI
Miniaturized Button-Like WBAN Antenna for Off-Body Communication
Padmathilagam Sambandam,Malathi Kanagasabai,Rajesh Natarajan,M. Gulam Nabi Alsath,Sandeep Kumar Palaniswamy +4 more
TL;DR: The directional radiation pattern obtained from the developed antenna ensures the low backward radiation to the body tissue, thereby, making it more suitable for WBAN applications.
Journal ArticleDOI
A NOVEL SHIELD FOR GSM 1800 MHz BAND USING FREQUENCY SELECTIVE SURFACE
Ramprabhu Sivasamy,Malathi Kanagasabai,Sanjay Baisakhiya,Rajesh Natarajan,Jayaram Kizhekke Pakkathillam,Sandeep Kumar Palaniswamy +5 more
TL;DR: In this article, the authors proposed a band stop function to shield the GSM 1800MHz downlink band with a unique geometry and the circular apertures endowed with it, which provides shielding efiectiveness of 20dB alongside with 133MHz bandwidth.
Journal ArticleDOI
A Compact Frequency-Reconfigurable Antenna With Independent Tuning for Hand-Held Wireless Devices
Sangeetha Subbaraj,Malathi Kanagasabai,M. Gulam Nabi Alsath,Sandeep Kumar Palaniswamy,Saffrine Kingsly,Indhumathi Kulandhaisamy,A.K. Shrivastav,Rajesh Natarajan,Shanmugapriya Meiyalagan +8 more
TL;DR: In this article, the design of a compact loop antenna with independent frequency tuning is presented, which consists of a feed line fed by a $50~\Omega $ coaxial probe and four resonating arms on the adjacent sides of the feed line.
Journal ArticleDOI
Modified antipodal Vivaldi antenna for ultra-wideband communications
Rajesh Natarajan,Jithila V. George,Malathi Kanagasabai,Livya Lawrance,Balaji Moorthy,Dinesh Babu Rajendran,Mohammed Gulam Nabi Alsath +6 more
TL;DR: In this article, a modified antipodal Vivaldi antenna (AVA) with low cross-polarisation is proposed for ultra-wideband communications, where the bandwidth offered by conventional single petal AVA is enhanced by adding another petal.
Journal ArticleDOI
Design of an X-band Vivaldi antenna with low radar cross section
TL;DR: In this paper, a passive Vivaldi antenna design is proposed for radar cross section (RCS) reduction using object shaping method, the implementation of annular slot along with exponential curves in the radiator reduced the scattering along the surface of the radiator.
