Antenna is a vital component in wireless application systems. The microstrip antenna can be used for wireless applications as it has features such as light weight, easily mounted and it is easy to mass produce. Although there are many features that suits well for microstrip antenna to be deployed for wireless applications, there is a very serious limitation where it has a very narrow bandwidth....

In this paper, the bandwidth enhancement of TIA amplifier can be design for achieving the high information capacity which is used in optical fiber communication for existing transimpedance amplifiers in CMOS technology. The proposed TIA amplifier also trade-offs between gain, bandwidth, noise, and group delay variation with introduce on differential architecture along an RGC network as input an...

This paper proposes a bandwidth-scalable coding scheme based on the G.729 standard as a base layer coder. In the scheme, according to the channel conditions, the output speech of the decoder can be selected to be narrow-band (4-kHz bandwidth) or wideband (8-kHz bandwidth). The proposed scheme consists of two layers: base and enhancement. The base coder uses the G.729 algorithm to encode narrow-...

A compact center shorted rectangular microstrip antenna has been discussed. The bandwidth enhancement of the compact MSA has been realized using gapcoupled multi-resonator technique, which gives the bandwidth of more than 20%.
