Multi-L Slots Antenna for Multiband Applications

This research paper present a multi-L shaped slots antenna (MLSSA) for multiband operation, the aim of this study is to design small and simple profile antenna that can operate in multiband frequency, the proposed antenna contain a rectangle microstrip patch with a small overall size of 27.4×24 mm
²
and a transmission line with 50 Ω coplanar waveguide (CPW), the bands characteristics are realized by introducing a six of L-shaped slots in radiating element, the prototype and proposed antenna have been constructed and experimentally studied. The measured S11 shows a good agreement with the simulated one, thereby the antenna respond at five frequency bands which are (2.36-2.58 GHz), (3.07-4.01 GHz), (4.25-5.27 GHz), (5.9-6.29 GHz) and (7.01-S.l GHz) to meet requirements for WILAN (5.15-5.S75 GHz), WIMAX (3.3-3.7 GHz), LTE band (3.2-3.3 GHz) applications.
