A Miniaturized Wideband Planar Bow-Tie Slot Antenna with Asymmetric CPW

open access: yesInternational Journal of Antennas and Propagation, 2022
In this paper, a novel miniaturized wideband planar bow-tie slot antenna is proposed. For the purpose of miniaturization and wide bandwidth, the effects of the dimension and shape of the bow-tie slot and feed structure are analyzed. This antenna adopts a

Electromagnetic Scattering of Rough Ground Surface Covered by Multilayers Vegetation

open access: yesInternational Journal of Antennas and Propagation, 2019
A microwave scattering model is proposed for the ground surface covered with multilayers vegetation. The vegetation leaves are simulated with the discrete elliptical particles in layers, which are randomly distributed above the randomly rough surface ...
