The power quality is the challenging criteria in all equipment's at all levels comprise industrial sectors and consumer places. Some parameters are very sensitive which may affect and disturb the power quality. These parameters are harmonic current, power compensation and voltage sag. Providing the source without these parameters with efficient power quality is essential. Hence by selecting proper device the power output may reach without any interruption along with linear, non-linear and unbalanced loads. This paper introduces a Sliding Mode Controller (SMC), a very effective controller implemented with Shunt active filter and Static VAR Compensator (SVC) FACTS device which increases the reactive power compensation and suppresses the harmonic to enhance the system performance with high reliability.

In this paper, a high gain small size antennas are micro ICCLMA (Inductively Coupled Capacitively Loaded monopole antenna) with circular patch and micro ICCLMA with rectangular patch is presented. These different types of patch antenna topologies were designed with same dimensions to produce higher gain. We begin with the comparison between the antenna designs, requirements and continue with a discussion issues and simulation results. Each antenna topology is then discussed including the limitations and advantages of each. In fact, each technique is uniquely designed to produce size reduction and higher gain antennas. Among two antennas the micro ICCLMA with circular patch provides higher gain as compared to other micro ICCLMA with rectangular patch. The antenna design simulation results were done by using CST Microwave Studio. The gain of micro ICCLMA with circular patch is 46.03 dB.
