This article describes the design of a new Slotted Elliptical Patch with Defected Ground Antenna (SEPDGA) for microwavebased imaging applications. The intended antenna comprises of a defective ground plane and multiple rectangular slotted ellipse-shaped patch. Multi-resonances can be exhibited by the designed antenna which merges to disclose the wideband spectrum. The experimentally verified antenna has a fractional bandwidth (FBW) of 79% and a functional frequency band of 1.3–3.0 GHz (< -10 dB). According to simulation-based outcomes, it operates between 1.4 -3.2 GHz and has an FBW of 78%. Additionally, the antenna prototype has achieved a highest gain of 4.9 dBi at 2.65 GHz and an efficiency peak of above 85%. In addition to demonstrating superior time domain behaviors as well as omnidirectional radiation properties across the entire operating spectrum. Featuring a compact size, decent gain, high fidelity, large band of operation and efficiency, as well as stable omnidirectional radiation characteristics, this antenna is perfect for applications in biomedical imaging.

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.
