In this paper hexagonal patch shape with hexagonal slot, ultra wideband antenna is proposed. The total dimensions of antenna are 55×43.5mm. Sides of hexagonal patch are taken 13mm each and hexagonal slot sides are taken as 3mm each. The antenna resonates at two frequencies in ultra wideband range (UWB). There is enhancement in BW in upper range ultra wideband frequency from 6.2 GHz to 8.2GHz du...

On-chip distributed transmission line resonators in CMOS technology have become the interest of research subjects recently (Ono et al. 2001; Umeda et al., 1994; Kanaya et al., 2006; Wolf, 2006) because of their size which becomes more compact, as the frequency of application increases. Among the various transmission lines, coplanar waveguide (CPW) has more engineering applications (Toyoda, 1996...

A coplanar waveguide (CPW) fed Ultra Wideband (UWB) slot antenna with reconfigurable rejection bands is presented in this paper. The antenna has a rectangular slot with triangular structure that acts as a tuning stub with CPW feed. The notch band is achieved by inserting a rectangular slot in the ground plane with a length of λ/2. The rejection of the bands 3.1 GHz – 3.9 GHz, 4 GHz–5.3 GHz and ...

A novel on-chip RF choke at 5 GHz is designed and measured for a class A operating Wireless LAN RF power amplifier (PA). The coplanar waveguide (CPW) based on-chip RF choke is implemented as an alternative component to inductors provided by the 0.35 μm SiGe BiCMOS technology. The CPW RF choke is designed at 5 GHz, and has a length of 1600 um and loaded with a capacitance of 0.95 pF. The measure...

Microstrip Patch antennas are very prevalent these days due to various attractive features possessed by them. Coplanar Waveguide (CPW) fed patch antenna has benefits of compact size, ease of fabrication and integration with other monolithic circuits. Moreover, the proposed design is very simple design fed with CPW feed. The proposed antenna performs dual band (1. 5 GHz and 7 GHz) operation with...

A lumped-element circuit is proposed to model a coplanar waveguide (CPW) interdigital capacitor (IDC). Closed-form expressions suitable for CAD purposes are given for each element in the circuit. The obtained results for the series capacitance are in good agreement with those available in the literature. In addition, the scattering parameters obtained from the circuit model are compared with th...

The accurate estimates of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of highperformance integrated circuits and integrated circuits packaging. In this paper, the quasi-TEM analyses of multilayer coplanar waveguide (CPW) broadside coupled-line balun are successfully demonstrated using Finite Element Method (FEM). We sp...
