This paper presents the design and realization of a compact size multimode frequency reconfigurable antenna.The antenna consists of a triangular-shaped monopole radiator, originally inspired from a rectangular monopole antenna.Slots were utilized to notch the desired frequency while the PIN diodes were utilized to achieve frequency reconfigurability.The antenna can operate in wideband, 2014 dodge ram 1500 fender flares dual-band, or tri-band mode depending upon the state of the diodes.To validate the simulation results, a prototype was keychron m4 fabricated, and various performance parameters were measured and compared with simulated results.

The strong agreement between simulated and measured results along with superior performance as compared to existing works in the literature makes the proposed antenna a strong candidate for ISM, 5G-sub-6 GHz, and S-band applications.
