—A novel flexible printed monopole antenna with a windmill-shaped fractal design, which is fed by co-planar waveguide (CPW) is presented in this manuscript for ultra-wideband (UWB) applications. By integrating a modified windmill-shape fractal into the conventional irregular hexagonal-patch, the antenna achieves a significantly wider impedance bandwidth extending up to 156.6% across the frequency band of 1.37–11.25 GHz. Additionally, increasing the number of the windmill-shaped fractals leads to the emergence of further resonances. The overall dimensions of the designed antenna are 50 × 70 × 0 . 2 mm 3 , and it boasts an impressive bandwidth-dimension ratio (BDR) of 4457, showcasing exceptional efficiency in utilizing its compact size. The maximum gain reaches 4.8 dBi, while the radiation efficiency attains an impressive 98%. The modified windmill-shape fractal antenna design leverages the multifractal concept, providing monopole antennas with enhanced flexibility in controlling resonances and bandwidth. This manuscript offers a comprehensive presentation and discussion of the process used to improve the impedance bandwidth, shedding light on the antenna’s exceptional performance and capabilities.

|A narrowband, high selectivity Substrate Integrated Waveguide (SIW) bandpass (cid:12)lter with perturbing vias and CSRR is proposed for Sub-6 GHz applications. Firstly, the perturbing vias are positioned at the symmetrical axis of the SIW cavity which produces distinct electric (cid:12)eld distribution for the (cid:12)rst two modes. Next, the ground plane is engraved with the CSRR placed at an offset distance on either side of the perturbing vias, forming the coupling arrangement that combines mixed and magnetic, electric coupling. The presence of CSRRs resulted in a narrowband (cid:12)lter. The (cid:12)lter’s center frequency is 4.947 GHz with a fractional bandwidth of 1.16%. By comparing the fabricated (cid:12)lter to an existing SIW conventional multi-cavity or cascaded resonator, a size reduction of 117% is achieved. The simulated and measured results agree with each other.

|Recon(cid:12)gurable antenna arrays play a major role in the current and future wireless communication systems due to their multifunctional capabilities and many other advantages. Conventionally, the array pattern recon(cid:12)gurations were usually achieved by controlling the excitation amplitudes and phases of all or most of the array elements which are generally costly and complex methods. In this paper, a simple method for controlling the recon(cid:12)gurability of the beam-patterns of linear and planar arrays is presented. It can be easily switched between narrow and wide beams using thinned elements strategy. First, the array elements are divided into three groups based on their locations namely central, middle, and outer elements. Their amplitude weights are chosen to be unity, adaptive, and zero, respectively. To add some desired constraints on the array beam-patterns such as limited sidelobe level and speci(cid:12)ed nulls placement, the excitation weights of the middle elements are optimized such that an abrupt change in the array taper is avoided. This also avoids an undesired change in the sidelobe pattern. A genetic algorithm is used to perform such optimization so that the produced beam-patterns are best matched to the desired ones. Moreover, the size of the thinned region controls the resulting beam width.
