Ultra-wideband PIFA with a convex-shaped feeding line
Jose Alfredo Tirado-Mendez,Rene Acevo-Herrera,Flavio Iturbide-Sanchez,Ruben Flores-Leal,Roberto Linares-Miranda,Hildeberto Jardon-Aguilar +5 more
TL;DR: In this paper, an ultra-wideband planar inverted-F antenna is presented, fed by a convex-shaped structure, which shows an omnidirectional pattern at the X-Y plane with a very low out-of-roundness all over the bandwidth.

UWB power propagation for bio-medical implanted devices
TL;DR: A study of ultra wideband (UWB) technology to compute the energy transmission level as an electromagnetic impulse traveling from the transmitter antenna into the human body, and reaching the receiver antenna, indicates that despite the increasing frequency from 3.5 GHz to 6.1 GHz, there is only minor power variations at the receiver.

A Study of the Effects of Symmetric and Asymmetric Design for CRLH-TL Unit Cell on XPD and Isolation for Dual Linear Polarized Antenna at Different Values of Phase Shifts
TL;DR: In this paper, a new design of a dual linear polarization single microstrip patch antenna with low cross-polarization pattern and high isolation between two input ports is presented, which results in significant improvement in co-cross polarization discrimination at the phase shift of 40o in comparison to the conventional antenna.
