US6677909B2 - Dual band slot antenna with single feed line - Google Patents
A dual band slot antenna ( 1 ) for an electronic device includes an antenna body ( 10 ) with elongated first and second slots ( 11, 12 ) defined therein and a coaxial feeder cable ( 20 ) having a conductive inner core wire ( 21 ) and a conductive outer shield ( 22 ). The inner core wire is electrically connected to the antenna body at an outer side of the first slot 11 and the outer shield is electrically connected to the antenna body at an opposite, outer side of the second slot. The coaxial cable acts as a common feed line of the first and second slots.
Dual band triangular slotted stacked microstrip antenna for wireless applications | Central European Journal of Engineering
In this paper stacked configuration of microstrip antenna is used to produce dual wide band which is suitable for various wireless applications. Using triangular slot and stacking of foam substrate of dielectric constant 1, two bands of bandwidth 18.70% and 12.10% is obtained. The antenna is fed by coaxial probe feeding technique. The proposed patch antenna is designed on the foam substrate and simulated on the Zeland IE3D software.
Design of CPW-fed asymmetric slot UWB antenna for wireless application | Journal of Electronics (China)
A compact Ultra-WideBand (UWB) slot antenna is presented in this paper. The slot is modified rectangular in shape and asymmetrically cut in the ground plane. A hexagonal patch with two stepped CoPlanar Waveguide (CPW) feed is used to excite the slot. Wider impedance bandwidth is achieved due to the extra inductive reactance created by the asymmetric slot which neutralizes the capacitive reactance of the hexagonal patch. The measured impedance bandwidth of the proposed antenna is 11.85 GHz (2.9–14.75 GHz). The radiation patterns of the proposed antenna are obtained and found to be omni-directional in H-plane and bi-directional in E-plane.
