This paper presents the design, simulation and fabrication of a new microstrip antenna belonging to the Ultra-Wideband (UWB) category, operating in the frequency range of 3.8973 GHz to 11.251 GHz. The antenna design integrates a Coplanar Waveguide (CPW) feed line and a hexagonal slotted fan-shaped net resonator, employed on an FR4 substrate with a dielectric constant of 4.4 and thickness of 1.6 mm. From the outcomes of this research, it is clear that the antenna model can cover the entire UWB frequency range with an operational bandwidth of 7.3536 GHz and an input return loss lower than -10 dB and unlike conventional planar antennas or microstrip patch antennas; this antenna has bipolar radiation patterns. Given its low weight, favorable radiation pattern as well as frequency response, the compactness of this antenna creates it a suitable candidate for potential medical applications in WBANs and healthcare applications. Accordingly, it can be one of the most promising technology alternatives targeting wireless communication and sensing in next-generation healthcare solutions.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
