A Compact Circular Patch Antenna with Efficiency Enhancement using Annular Slot DGS
This paper presents a circular patch antenna that enhanced efficiency by employing annular slot DGS (defected ground structure), meant for n77 and n78 band applications. The proposed antenna consists of an inset-fed circular radiation mounted on the top surface of 1.6 mm thick FR4 lossy substrate. At the substrate’s bottom side, an annular slot-loaded DGS is added in an effort to enhance the antenna efficiency. This compact antenna design works at 3.5 GHz with a fractional bandwidth (FBW) of 7.3%, operating between 3.38 GHz to 3.63 GHz. The proposed circular patch antenna offers a high efficiency exceeding 60%, without sacrificing the antenna gain.
