“…In (5) , a rectangular UWB antenna, which is capable of supporting wide BW of 3-10.26 GHz by adding suitable slits and slots in the patch and ground, was proposed. An antenna for wireless applications was introduced in (6) which was also acted as UWB antenna by providing a polygonal slot in the plane of ground. The enhancement of BW can be achieved in (7) by utilizing CMA (Characteristic Mode Analysis) technique along with the structure of defected ground.…”

Objectives:The main objective of this article is to present a novel corner defected ultra wideband (UWB-3.1 to 10.6 GHz) rectangular patch with a partial ground plane to enhance the bandwidth with multi-resonance characteristics. By defecting the corners, the original rectangle patch will be converted into defected shape of proposed one to satisfy the objective. Methods: A FR-4 substrate with height (h) of 1.6 mm, dielectric constant (ε r ) of 4.3 and the loss tangent of 0.025 was used to develop the required antenna. The antenna was excited by a 50 Ohm microstrip line. This antenna was designed, simulated and analyzed by using MS-CST (Microwave Studio -Computer Simulation Technology) to attain the outcomes such as return loss (S11< -10 dB), voltage standing wave ratio (VSWR < 2), improved gain, Omni-directional radiation patterns, and enhanced bandwidth. Findings: It exhibits a fractional bandwidth (FBW) of 152.9 % between 2 GHz and 15 GHz. The antenna resonates at multiple frequencies owing to truncation of corners and produces resonant frequencies of 3.87 GHz and 11.36 GHz with the corresponding return losses of -26.03 dB and -34.87 dB respectively in the simulation point of view. The antenna was fabricated and tested. The measured and simulated results of the desired antenna were compared, and they show good agreement. Applications: The proposed antenna is suitable for UWB, WiMAX (Worldwide Interoperability for Microwave Access), C and X -band communications.
