Abstract	This paper presents a novel structure of frequency reconfigurable truncated rhombus-like slotted antenna (FRTRSA). The structure consists of a slotted ground plane with a thickness of ho sandwiched between two different substrates of different thicknesses, $h_{1}$ and $h_{2}.$ The upper substrate has lower dielectric constant, $ε_{rι}$ than the bottom $substrate,ε_{r2}.$ Unlike a conventional antenna which provides only one frequency per antenna, the proposed antenna is focused to operate at two different frequencies in a single antenna by using corporate feed array configuration. A 'zig-zag' slot which is embedded at each radiating patch at two different orientations in xand y-axis has significantly influenced the excitations of the resonant frequencies. Therefore, the uniqueness of the antenna is that it has the same patch size although two different frequencies are achieved. The antenna integrated with the PIN diodes at its feed network to reconfigure the desired frequency. CST Microwave Studio has been used for design simulation and optimization. Simulated and measured results are presented and both results are in a good agreement. The results confirm that the antenna can be reconfigured at two frequency modes, $F_{1}=5.3GHz$ and $F_{2}=5.8GHz.$ The proposed antenna has given a great advantage on the lower frequency with patch size reduction of 37.09%.
