Abstract In this article, bandwidth enhancement of a microstrip patch antenna using new kind metasurface is discussed. This geometry used to generate resonances in and with an optimal position the relation we can overlap obtain large bandwidth. The proposed showed from 5.1 GHz 8.0 what it able be applied WiFi 5 6. Numerical results were obtained Ansys HFSS software. A prototype was built measur...

In this paper, we analyze a distributed amplifier based on input/output attenuation compensation. The analysis is carried out for a HEMT transistor; and a constant-k section filter is used to calculate the amplifier’s characteristics such as attenuation factor, phase constant and gain. The proposed design approach enables us to examine the tradeoff among the variables, which include the type an...

A newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (UWB) applications. The two band notches of this coplanar waveguide (CPW) fed antenna are achieved by an M-shaped slot (MSS) embedded in the radiating element and a C-shaped strip (CSS) close to ground plane, therefore two very narrow rejected properties in the wireless lo...
