In this paper, the Ku-band rectangular microstrip patch antenna (RMPA) is intended to operate in the dual-band for satellite communication (SATCOM). The antenna which is obtained for dual-band by utilizing a U-slot and vertical slits on RMPA is fed with a micr…

Robot algorithms require faster and more efficient computing due to increasing integration of robot arms to automation systems and expanding capabilities of robotic systems. Inverse kinematics calculations used in trajectory generation is one of these algorith…

2020 yılına kadar büyük veri gereksinimi ile birlikte kullanıcı sayısının hızlı bir şekilde artmaktadır. Yeni nesil hücresel iletişim teknolojilerinin bu veri trafiği ile beraber daha yüksek veri hızlarını desteklemesi beklenmektedir. Yaklaşan 5.nesil (5th Gen…

Several statistical analyses of the Pisarenko harmonic decomposition (PHD) method for frequency estimation of a single real sinusoid in noise have been carried out in the literature. However, all of the analyses consider the phase of the sinusoid as a constant…

Instantaneous estimation of the frequency of a real sinusoid in noise from a small number of data samples is an important problem in the signal processing area. Several frequency estimators are proposed for this problem in the literature. In this paper, some o…

Design and usage of Unmanned Aerial Vehicles (UAV) especially for military purposes has been rapidly increasing in recent years due to their capability to endure long flight durations without needing a crew and due to their low cost compared with the conventio…

A microgrid is a power grid consists of distributed power generation units and loads. Microgrid is also a system that can operate in grid-connected mode and islanding (autonomous) mode. The control of distributed power generation units in microgrids is necessa…

Micro-strip patch antenna has penetrated deep in the market due to its advantages. After studying micro patch antennas, there are some draw backs of it. One of the drawbacks includes the narrowband performance. The primary reason for this is its resonant natur…
