This paper presents an advanced design of high-gain slot antenna array at K-band using slots as radiating elements serially fed by coplanar waveguide (CPW). The arrays consist of identical slots of rectangular shape positioned symmetrically relative

A new geometry for uniplanar, ultra-wideband monopole antenna has been proposed for operations in the 1.8–30 GHz band, thanks to its fractal structure in the form of a cardioid. The antenna has extremely small dimensions at 0.21λ × 0.285λ at the

Coupled-mode theory is applied to obtain an analytic form of scattering parameters for a class of transmission line metamaterials with antisymmetric split-rings. The same structure is modeled with equivalent circuit, which includes electric and magne

In this letter, a design procedure of the K-band slot antenna array in corner reflector is described. The array consists of eight slots as radiating elements with parallel-series feeding by coplanar waveguide (CPW) transmission line. The uniform rect

This paper presents a simple design of linear series-fed frequency scanning antenna arrays with: (a) identical rectangular dipoles and (b) pentagonal dipoles having different impedances to provide enhanced side lobe suppression. Phase shifters are de

In this paper, a novel design of a patch antenna with two symmetrical slits and two closely spaced resonances is proposed. A novel patch antenna demonstrates a great flexibility in impedances adjustment at both resonances that are of a great importan

In this paper, we propose an approach that uses deep learning to detect a human fall. The proposed approach automatically captures the intricate properties of the radar returns. In order to minimize false alarms, we fuse information from both the tim
