A polarized wideband slot array antenna is proposed for active antenna system (AAS). The proposed array has a planar structure that integrates all the elements on a single substrate. Metal columns are used to reduce the coupling between adjacent elements. A prototype of a 2 2 array antenna is fabricated and measured. The measured results show that the proposed array covers...
A novel wideband printed dipole antenna suitable for wireless mesh network (WMN) application is proposed in this paper, with VSWR<1.6's bandwidth greater than 31% at 5.5GHz, covering the WLAN upper band. When arranging the dipoles for an E-plane array, two parasitic elements are utilized on both sides of the array to achieve a 25-degree beamwidth in the E-plane so that the array could deal with...
In this paper a tapered slot antenna array has been analyzed and designed. Both the simulation and measurement results show that the antenna array has scanned impedance bandwidths over the frequency band of 1.8-9 GHz and scan angle up to 45deg. This work reveals that the strong mutual coupling between elements has good effects to the overall performance of the array. It can be well used to achieve...
We have developed a 1 times 4 wideband array structure for multiple wireless applications. The utilized single element is a wide-slot antenna and has demonstrated ultra-wideband operation characteristics. The proposed antenna system associated with feeding network and antenna elements can be integrated in a single substrate. Consequently, such a design is with low fabrication and assembly cost and...
