Diamond-shaped metasurface low-profile wideband antenna

The Journal of Engineering, 2019
A low profile wideband metasurface (MTS) antenna based on periodically modulated diamond-shaped patch is presented. The proposed antenna consists of diamond-shaped MTS patches and a slotted antenna fed by a microstrip line, which excites both the quasi ...

High efficiency wideband printed monopole antenna with enhanced gain using artificial magnetic conductor surface

Scientific Reports
Combining the benefits of a low profile, high gain, high efficiency, and wideband operation in a planar antenna presents a significant challenge for antenna designers. Low-profile wideband antennas often suffer from low gain.

Towards a hardware implementation of ultra-wideband beamforming [PDF]

, 2010
This paper discusses and analyses the hardware implementation of an ultra-wideband (UWB) beamformer for UWB Impulse Radio data transmission. We use a Complex Programmable Logic Device (CPLD) acting as the binary baseband information source.
