Abstract
A Compact Dual Band-Notched Circular Ring Printed Monopole Antenna for Super wideband Applications
Highlights
Nowadays there is an increasing demand of super wideband (SWB) radios in the modern wireless communication systems, owing to their extremely large bandwidth (BW) and very high data transmission rate
Printed monopole antenna (PMA) is an ideal candidate for SWB applications due to its several fascinating features such as small size, low cost, planar structure, operation over extremely large impedance BW and ease to accommodate with small space provided by hand held gadgets
Several dual band-notched (DBN) UWB antennas have been investigated by many researchers across the globe [8,9,10,11,12,13]
Summary
Nowadays there is an increasing demand of super wideband (SWB) radios in the modern wireless communication systems, owing to their extremely large bandwidth (BW) and very high data transmission rate. It is to be noted that some of the existing narrow-band systems such as WiMAX (3.3–3.6 GHz), C-band (3.7–4.2 GHz) and X-band satellite communication systems operating in 7.25–8.395 GHz (for down link: 7.25–7.745 GHz and uplink: 7.9–8.395 GHz) may cause electromagnetic interference (EMI) to the SWB system. To mitigate this electromagnetic interference issue, SWB antennas with band-notched characteristics is required. To the author’s knowledge, there are no DBN SWB antennas reported in the literature In this communication, a novel and compact DBN SWB PMA is presented. Simulation results have been carried out with the finite element method (FEM) based commercial software Ansoft high-frequency structure simulator (HFSS)
