Meander line antenna (MLA) is an electrically small antenna which poses several performance related issues such as narrow bandwidth, high VSWR, low gain and high cross polarization levels. This paper describe the design ,simulation and development of meander line microstrip antenna at wireless band, the antenna was modeled using microstrip lines and S parameter for the antenna was obtained. The...
In this paper, a SIW horn antenna is designed using Luneburg lens in order to enhance the gain. Using a transition printed on the same substrate, both the matching performance and the front to back ratio was improved. In addition, this transition structure allows the antenna to be planar. The proposed antenna operates at 14.5 GHz and can be used for Ku band application.An antenna prototype was ...
In this paper, A lens antenna with high gain is proposed. The composed of the microstrip and hemisphere dielectric lens, loaded on top. polyethylene used to fabricated lens. has dimensions 47.58 mm × 24.79 mm, which corresponding electrical size 1.586λ0×1.586λ0×0.826λ0, where λ0 free-space wavelength at 10GHz. impedance bandwidth (return loss<-10dB) 12.7%(9.24 GHz-10.51 GHz), peak 9.06 dBi. ...
