The Integrated Optics has resulted in miniaturization of optical devices. Bent waveguides have replaced straight waveguides in optical integrated circuits for such reasons. In the proposed work, curved/bent waveguide is basic structure for generating delay and hence the phase shift. A differential phase shift is obtained by the differential length change between the straight waveguide and a S-b...

Millimetre-wave frequencies are defined as one of the front-runner contenders for body-centric wireless communication. In this study, low-profile antenna with substrate integrated waveguide (SIW) has been proposed that operate in band millimetre-wave frequency centred at 60 GHz. The implemented use FR4 εr and tangent loss 4.3 0.025, respectively. height size 1.5875 mm 20 x mm, performance is ev...

This paper presents a quasi-elliptic filter (QEF) with arbitrary termination impedances (ATI). The proposed QEF is designed by adding cross-coupling between the first and last resonators of an ATI bandpass (BPF) Chebyshev response. QEFs can be in even-order location pair transmission zeros (TZs) controllable. To prove validity design, fourth-order were implemented on single-layer substrate-inte...
