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 antennas truncated ground-plane incorporates a central notch. This modification significantly improves the antennas impedance bandwidth by 118% over an ultra-wideband frequency range. T...

متن کاملBand-reject ultra-wideband monopole antenna using patch loading
Proposed is a new simple technique for achieving band rejection characteristics in ultra-wideband monopole antennas. Two band notches were added to an existing UWB antenna by gluing a padding patch printed on a small single-layer piece of commercial substrate. The design of the new proposed structure has a controllable rejection in the 5 GHz WLAN and 8 GHz ITU frequencies while maintaining a wi...
متن کاملA Novel Ultra-Wideband Monopole Antenna with Band-Stop Characteristic
In this letter, a simple monopole antenna with variable band-notched characteristic for ultra wide band (UWB) function is proposed. Two L-shaped quarter-waveguide resonators coupled to the ground plane with two shorting tracks at the sides of the antenna are used to generate stop-band performance around 5.5 GHz (WLAN). The proposed antenna is fabricated on the substrate FR4 (relative permittivi...
متن کاملA New Compact Ultra Wideband Printed Monopole Antenna with Reduced Ground Plane and Band Notch Characterization
In this paper, a printed monopole antenna with reduced ground plane has been presented as a candidate for use in ultra-wideband applications. The monopole antenna structure is a nearly square shaped with m-slot embedded in it. A 50Ω microstrip line is used to feed the proposed antenna. The proposed antenna has been supposed to be etched using a substrate with relative permittivity of 4.6 and th...
