Compact Folded Monopole Antenna Excited by a Conductor - Backed Coplanar Waveguide with Vias
© 2013 ETRI Journal, Volume 35, Number 3, June 2013 A compact monopole antenna excited by a conductor-backed coplanar waveguide (CBCPW) is developed for wireless USB dongle applications. The proposed antenna has a compact dimension of 14 mm × 47.4 mm × 3.5 mm, which is suitable for a USB dongle housing. A slotted elliptical patch and a CBCPW with vertical vias are employed to achieve a further ...
متن کاملWiMAX/MIMO Antenna using L-shaped Folded Monopole Antennas
In recent days, the Worldwide Interoperability for Microwave Access (WiMAX) technology has widely used for wireless mobile devices such as handsets, notebook PCs and so on. In addition, Multi-antenna systems for handsets such as diversity and Multiple-input Multiple-out (MIMO) applications has developed, which are seen as the potential technologies for enhancing the performance and capacity wit...
متن کاملUltra 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 کاملInput impedance antenna automatic matching system
This paper presents a new design for an input impedance antenna automatic matching system. In order to achieve this main objective, it is necessary to accomplish several intermediate tasks. On the one hand, a study about the implementation of a generic electronically tunable impedance synthesizer is carried out. Then, a prototype based on the research is constructed, and its characteristics and...
متن کاملMonopole Antenna Radar Cross Section Reduction with Plasma Helix
In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber without disturbing the antenna performance. The simulations show that radar cross section of simulated antenna is reduced in a wide frequency ...
