This paper discussed about the effect of different substrates on slotted Log Periodic Fractal Koch Antenna (LPFKA). This log periodic antenna is comprised of ten radiating elements with titled slot angles and placed on both sides of the substrate in crisscross arrangement. This LPFKA was designed at frequency between 0.47 GHz and 0.79 GHz which focus on UHF TVWS bands. A comprehensive study between...
Influence of hand on the MIMO antenna performance for future 5G terminal has been studied and presented in this paper. The study covers on performance for mobile terminal operating at 5.0 GHz with 1 GHz bandwidth at −6 dB. Development of this study is due to the concern from service provider and mobile designer in developing a small and compact mobile terminal. The effect of users finger is studied...
A reconfigurable MEMS beam steering array (RMBSA) antenna for smart radar application is proposed. The RMBSA antenna is designed with a coaxial probe technique as the medium to feed the current to the centre of the RMBSA antenna before the current is shared out to the radiating elements. This research successfully invented beam steering capability by using Micro-Electro-Mechanical System (MEMS) as...
This paper investigates the performance of a circular patch antenna deployed with a parasitic ring and compares the performances with a conventional circular patch antenna in terms of gain, return loss, and radiation pattern. The antenna is fed by a coaxial probe and provided with a full ground plane. Compared with previous gain enhancement methods, the proposed metal ring resonator offers reduced...
