This work presents a new planar multiband antenna based on fractal geometry. This structure is optimized and validated into simulation by using CST-MW Studio. To feed this antenna we have used a CPW line which makes it easy to be incorporated with integrated circuits. The simulation results presents a good matching input impedance and radiation pattern in the GSM band at 900 MHz and ISM band at...

Various Coplanar Waveguide fed microstrip antennas with different ground planes and different radiating patches for broader bandwidth are proposed. The effect of changing periphery of the radiating patch from square to pentagon, pentagon to hexagon, hexagon to octagon and octagon to circle on resonance curve is studied. Similar study has been done by changing the shape of ground plane. The conf...

In this paper compact alignment and position sensors based on coplanar waveguide (CPW) transmission lines loaded with split ring resonators (SRRs) are proposed. The structure consists of a folded CPW loaded with two SRRs tuned at different frequencies to detect both the lack of alignment and the two-dimensional linear displacement magnitude. Two additional resonators (also tuned at different fr...

The paper presents the design of a novel ultra-wideband microwave crossover for the use in microstrip circuits. The proposed structure includes a double microstrip-coplanar waveguide (CPW) vertical interconnect in single-layer substrate technology which allows an inclusion of a finite-width coplanar waveguide (CPW) on the top side of the substrate to achieve the required cross-link. The present...

Abstract This paper presents wideband split-ring antenna arrays based on substrate integrated waveguide (SIW) for Ka-band (26.5–40 GHz) applications. The array is fed by a 2.92 mm coaxial connector (K-connector) and the power equally distributed to each resonator. designed coplanar (CPW), SIW, CPW-to-SIW transition, coaxial-to-CPW two-stage SIW divider are described in detail. By using thin Rog...

This paper presents the latest advances in extending semiadditive process (SAP) methods to 2–5 μm lines and spaces, achieved using dry film photoresists on thin glass substrates, toward meeting the routing requirements for 20-μm bump pitch interposers. High-density chip-to-chip interconnections on 2.5-D interposers are a key enabler to meet the high logic to memory bandwidth needs of next-gener...

Since the FCC has announced to allow the unlicensed use of the industrial, scientific, and medical (ISM) frequency band by any potential users, wireless communications community has provided enormous opportunities for driving many wireless systems that can be communicated over short distances. For example, some practical applications are operated at the internationally available unlicensed ISM ...

Coplanar-slotline tees have been used in a number of microwave circuits, although no complete models were available to explain their behavior. In this letter, a new “circuit-model” for a coplanar-slotline tee is presented. The model, based on the separation of coplanar waveguide (CPW) even and odd modes into two different ports, explains the tee’s behavior even if CPW air bridges are not used a...

Design and performance of a coplanar waveguide (CPW) bandpass filter (BPF) using Composite Right/Left-handed (CRLH) Zeroth-order Resonators have been studied. The Bloch analysis is applied based on the S parameters to derive the characteristics of the eigenmodes (Bloch modes), from which the right/left-handed frequency band and the zeroth-order resonant frequency are clearly determined. Then, t...

The symmetry properties of split ring resonators (SRRs) are exploited for the implementation of novel sensing devices. The proposed structure consists of a coplanar waveguide (CPW) loaded with movable SRRs on the back substrate side. It is shown that if the SRRs are placed with the slits aligned with the symmetry plane of the CPW, the structure is transparent to signal propagation. However, if ...
