A uniplanar, compact electromagnetic band-gap (UC-EBG) structure based on modified semi-Spidron fractal and meander-line strip (SFM-EBG) patterning is proposed. The semi-Spidron fractal geometry significantly increases the equivalent capacitance, whereas meander-line strips increase the equivalent inductance; as a result, the proposed design can be used to successfully miniaturize an EBG structure having a wide operating bandwidth. The measurement results show that a center frequency reduction of 32.14% as compared to that achieved by a conventional UC-EBG structure can be achieved by utilizing this proposed structure. The SFM-EBG structure has a measured operating bandwidth of 39.7% (3.33-4.98 GHz), which is wider than that of a conventional UC-EBG (31%).
