The antenna performance is seen from the S-parameter value. The S-parameter graph can be seen as the return loss (S11, S22) and the mutual coupling (S21, S12) value. This research focuses on analyzing mutual coupling on Square and Vivaldi array antennas u... see more

An important issue in antenna array design is reduction of mutual coupling. In square microstrip antennas this reduction can be achieved by using electromagnetic band-gap (EBG) structures. They can help in the reduction of mutual coupling by using their c... see more

In this paper an approach of obtaining optimal planar antenna arrays consisting of omnidirectional sensors is proposed. The novelty of the proposed approach is to apply an exact expression of the Cramer-Rao lower bound for an arbitrary planar antenna arra... see more

The integrity of signal environment for a navigation system among other factors depends critically on the capability of the adaptive antenna array in controlling (reconfiguring) its radiation pattern for various signal scenarios. For a signal environment ... see more

A flexible monopole antenna combined with a flexible frequency selective surface (FSS) is presented in this work. Initially, the FSS structure is examined by constructing a unit cell of the periodic FSS structure with (3x3) arrays of square loops. On a th... see more

Smart antenna has been recognized as a promising technology to improve wireless communications. Interference suppression, power consumption reduction and high data rates support are some of its advantages. Radio frequency identification (RFID) demands pow... see more

Estimating the parameters of a geometric propagation model from MIMO channel sounding measurements will be considered, which requires the solution of an inverse problem. Thus, a model of the measured data is derived, which incorporates a model of the meas... see more

The development of 5G technology is expected to result in high data rate communication, low power consumption and larger network capacity. Microstrip antenna is an antenna that can support 5G technology because it can work at high frequencies but has the ... see more

This research proposes a 5.8 GHz circular polarization double square edge antenna with a bandpass filter that used a method stepped impedance resonator (BPF-SIR) structure for designing a compact integrated antenna with the filter. the double layer electr... see more
