Abstract:
Design of a compact microstrip-fed ultra-wideband antenna suitable for USB dongle and other such space constraint applications is presented. The structure consists of a pentagonal monopole element and a modified ground plane that gives an impedance bandwidth from 2.8 to 12 GHz. Radiation patterns are stable and omni-directional throughout the band with an average gain of 2.84 dBi. The antenna occupies only 11 × 30 mm2 on FR4 substrate with permittivity 4.4.
The paper presents a maximally flat compact
planar filter employing folded Stepped Impedance
Resonators (SIR) and Complementary Split Ring
Resonators (CSRR), for Ultra Wide Band (UWB)
applications. An interdigital quarter wavelength coupled
line is used for achieving the band pass characteristics.
The filter has low insertion loss in its pass band and
steep roll off rate and good attenuation in its lower and
upper stop bands. The measured microwave
characteristics of the fabricated filter show good
agreement with the simulated response
