This research study presents a novel design of star-shaped fractal patch antenna for miniaturisation and backscattering radar cross-section (RCS) reduction. The proposed fractal antenna gives 50% size reduction compared with a conventional circular microstrip patch (CCMP) antenna. The antenna is studied experimentally for return loss behaviour using vector network analyser R&S ZVA40. It can be...
This paper presents the design of a star shaped circular microstrip fractal antenna. This star shaped circular microstrip fractal antenna has been designed on substrate with dielectric constant epsivr = 4.3 and thickness h = 1.53 mm. The antenna has been simulated using FDTD technique with dimension a = 40 mm. The simulated result shows the multiple resonances at 0.81 GHz, 1.47 GHz, 2.47 GHz and 3...
To achieve high data rates in next generation communication systems beyond 3G up to 100 Mbps or more research focuses on the open distributed wireless communication system called ODWCS which is a new architecture for a wireless access system with distributed & smart antennas (MIMO), distributed processors and distributed controlling through software defined radio (SDR) which is supposed to take...
This paper takes a brief overview of RFID technology to know what is Radio frequency identification, why to go with RFID, what are standards & different RFID techniques. It further explains the selection criteria & various application areas. In addition the paper also deals with problem areas.
This paper presents design of novel structure based on fractal geometry for minimum backscattering power using MOM method. The study reveals the optimum thickness of substrate for minimum backscattering power with respect to frequency is 9 mm with epsivr =2.2 for three iterative structure. It is clear that frequency of low RCS depends on thickness as well as geometry of structure. Low RCS has been...
