Abstract

This paper presents a compact single-feed, rectangular slotted-patched antenna (SPA) for UWB applications. The proposed design adds a triangular part of the tail of the rectangular patch, cuts the edge of the patch, etches a rectangular slot in the ground plane, and then tunes the basic parameters of the design to achieve the UWB passband. The proposed antenna including slots on the patch for compact functionality is readily identifiable. The bandwidth and realized gain of the UWB antenna can be extremely improved to show the ability of a slot loading technique. The new conception of the rectangular patch antenna is considered. A feed mechanism using an inset patch feedline is implemented and analyzed. The parameters of the antenna are demonstrated, and the antenna is fabricated with an inexpensive FR4 substrate and validated experimentally. The antenna occupies frequency band (2.56-12) GHz. Making slots in the modified patch results in a significant gain improvement of 4.8 dBi as well as extending the UWB passband. The measured values of the reflection coefficient, VSWR, realized gain, and power pattern are in good agreement with the simulated results.
