Ultra Wideband Monopole Antenna Excited by a Capacitive Coupling Feed with Double Band Notch Function

This paper presents the results of a new monopole antenna that exhibits 2.75-10.7 GHz performance. The proposed antenna consists of a radiating patch with notches excited by capacitive coupling feed. Also, the antenna’s truncated ground-plane incorporates a central notch. This modification significantly improves the antenna’s impedance bandwidth by 118% over an ultra-wideband frequency range. T...

Modified U-Slot Stacked Micro-Strip Patch Antenna for Ultra-Wideband Applications in S Band, C Band and X Band

The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...

Design and Analysis of Triple Notched Band Uwb Band Pass Filter Using Defected Microstrip Structure (Dms)

This paper presents design, simulation, fabrication and electrical analysis of a triple notched band UWB band pass filter. Short circuit stubs and microstrip line defected structures are used to design a triple notched band UWB filter. The proposed UWB BPF consists of five short circuited stubs of quarter wavelength attached to the feed line. The notched bands are created by introducing three U...

Triple Band Rectangular Microstrip Antenna for S & C Band Applications

In this paper, triple band rectangular microstrip antenna with two vertical rhombus shaped slot (TBRMA2VRS) is designed and developed for S and C band frequency applications. The triple bands are obtained by etching two rhombus slots on the patch surface. The impedance bandwidth of secondary band is enhanced from 2.06% to8.54% by replacing the two rhombus slots. The radiation patterns measured ...
