Symmetrical L-slots Reconfigurable Triple band Antenna for Mutiband Applications

Abstract

This paper introduces a novel compact reconfigurable antenna that utilizes monopole technology and tunable frequencies through switch control. The antenna is fed by a coplanar waveguide (CPW) and features a unique patch design with two L-shaped slots and integrated switches. This inventive design enables remarkable reconfigurability, allowing the antenna to operate within the frequency ranges of [3.8-3.93 GHz], [5.05-5.3 GHz], and [7-7.5 GHz]. These frequency ranges are strategically chosen to align with specific application requirements. The antenna also boasts an almost omnidirectional radiation pattern. The experimental outcomes highlight the efficacy of the proposed antenna, which occupies a compact footprint of 34x35.4 mm², making it particularly well-suited for applications requiring multiband functionality.
