A novel compact dual frequency reconfigurable microstrip antenna achieving polarization tuning by loading a single chip capacitor is presented. A cross shaped patch antenna with an X-slot constitutes the fundamental structure of the antenna. The tuning of the two resonant frequencies is realized by varying the effective electrical length of the slot with an embedded capacitor at the centre of the...
A compact CPW-fed planar monopole antenna for ultra-wideband applications is presented and investigated. The proposed antenna with a small size of 20 mm ×26 mm × 1.6 mm is composed of a staircase shaped radiating element fed by a CPW feed line, and an inverted stair-style ground. The measured results agree reasonably with the simulated ones. The proposed antenna yields a wide bandwidth ranging from...
The radiation pattern of a Coplanar Wave guide (CPW) fed printed monopole antenna is modified to that suitable for a mobile handset is presented and discussed. The printed metal stripes in the back side of the monopole modify the far field pattern ideal for mobile handset. The antenna offers a bandwidth of 200MHz when printed on a substrate of dielectric constant (εr) 4.4 and thickness 1.6mm with...
Compressed Sensing algorithms have provided feasible and reasonably accurate solutions to the problem of reconstructing signals of which only sub-Nyquist number of samples have been acquired. A framework called MOSAICS for acquiring multiple analog channels using limited number of A/D converters by exploiting CS based undersampling has been proposed in our previous work. In this paper we introduce...
