The design of a wideband circularly polarized pixelated dielectric resonator antenna using a real-coded genetic algorithm (GA) is presented for far-field wireless power transfer applications. The antenna consists of a dielectric resonator (DR) which is discretized into 8 × 8 grid DR bars. The real-coded GA is utilized to estimate the optimal heights of the(More)
This paper presents the design of a wideband circularly polarized antenna using a multiple-circular-sector dielectric resonator (DR). The DR is composed of twelve circular-sector DRs with identical central angles of 30 ∘ but with different radii. A genetic algorithm is utilized to optimize the radii of the twelve circular-sector DRs to realize wideband(More)
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 frac-tal geometry significantly increases the equivalent capacitance, whereas meander-line strips increase the equivalent inductance; as a result, the proposed design can be used to(More)
A meandered uniplanar compact electromagnetic band-gap structure is proposed. Meandered microstrip lines between adjacent cells are used to increase the equivalent inductance. As a result, the dimension of the proposed EBG structure is more compact and its frequency band-gap is wider than that of the conventional uniplanar EBG structure. Two patch arrays(More)
