In this article, we present a new design of a coplanar waveguide fed (CPW-fed) ultra-wideband (UWB) antenna with dual band-notched characteristics. Two notched frequency bands are achieved by using two inverted U-shaped stepped impedance resonators. The proposed antenna can operate from 2.82 to 11 GHz (118%), defined by VSWR< 2, except two notched bands around 3.5 GHz (WiMAX) and 5.5 GHz (WLAN)...

This paper introduces a new concept of coplanar patch antenna (CPA), which consists of a bow-tie shaped patch surrounded by closely spaced ground conductor and a coplanar waveguide (CPW) feed line. This novel configuration is proposed for use as an element of a phased array antenna specifically designed for radar systems. The main design goal is to devise a patch antenna that operates at 10 GHz...

In this paper one coplanar wide band bandpass filter (BPF) is designed with end-coupled λ/4 open-stub resonator. This coplanar waveguide (CPW) BPF is designed for passband centre frequency 2.5GHz and 100% fractional bandwidth (FBW) at 3dB. The proposed structure exhibits negligible passband insertion loss, sharp transition from passband to stopband, wide attenuation bandwidth, simple fabricatio...

This paper mainly presents a briefly review for recent progress in MEMS-based transmission lines for use in microwave and millimeterwave range. MEMS-based transmission lines including different transmission line structure such as membranesupported microstrip line microstrip line, coplanar microshield transmission line, LIGA micromachined planar transmission line, micromachined waveguides and co...

The constitutive parameters of most semiconductors, such as silicon and GaAs, are functions of temperature. Hence, the performance of passive and active device fabricated on silicon or GaAs substrate strongly depends on the operating temperature. Although passive devices are not so sensitive to the variation in temperature as active devices do, it is still necessary to examine the thermal effec...
