Design of Radio Over Plastic Optical Fibre for Broadband Indoor Access Network

Indoor wireless traffic increases exponentially. Radio over fibre technology has been used to provide broadband services in the access network. Plastic Optical Fibre (POF) has been considered as a promising waveguide to be used as backhaul link for indoor access network. The RoF system uses an improved POF cable as a backhaul. A photonic antenna is developed by integrating a microstrip patch antenna with an opto-electronic converter. A standard inset fed microstrip patch antenna used for the wireless transmission and reception is designed using CST software tool. A RoF communication system based on the developed POF is designed and simulated using Optisystem software tool. The Bit Error Rate (BER) performance of the system in terms of Quality factor is evaluated. A maximum achievable POF cable length of 117 m for an On-Off Keying (OOK) transmission data rate of 1 Gbps with an acceptable Quality factor of 7.0 is obtained. When the developed RoF system was used to transmit 10 Gbps and 50 Gbps data, the achievable cable lengths reduced to 80 m and 63 m, respectively.

Ku Band

The microstrip antenna required for higher frequency application is to be light in weight, easy to fabricate and small in size. As the applications in S-band and Ku-band are increasing with the increase in technology the requirement for higher data rate so the proposed work is to design a 24GHz (ka band) rectangular microstrip antenna with stripline feeding, return loss to be less than -20dB and VSWR less than 0.5. The substrate is chosen to be RT/duroid 5880 with relative permeability 2.2. it is capable of covering satellite application, telemetry. HFSS software tool is used to design the antenna.

Directive Gain

In connection with the development of radio communication systems, microwave, millimeter range, one of the most important is the problem of creating compact solid-state radiation sources. The antenna is the effective interaction between electronic circuits and the outside world is an important component of any wireless connection trend toward line the use of high frequencies in modern communications. Solutions, space technology, about (30 Ghz), Local Multipoint Distribution (LMDS) at 28Ghz) antenna technologies to meet the new requirements of the card actively participated in the elaboration of the various subsystems for such active monolithic Phased Array Antenna. This document is primarily.This paper mainly studies the effect of plasma wave on the radiation properties of a conically depressed microstrip patch antenna. Using linearized hydrodynamic theory and potential function technique, the total directive gain and quality factor are calculated for different values of plasma to source frequency and different half-cone angles. It is observed that the directive gain and quality factor are changes considerably by changing the half-cone angle as well as a plasma to source frequency values. © 2018 JASET, International Scholars and Researchers Association.

The Relationship

In this chapter, an equation is obtained using curve fit formula that shows the relationship between the simulated co-axial probe feed distance and theoretically inset feed distance in rectangular microstrip patch antenna. The simulation process is performed using IE3D simulation software tool and theoretical calculation performed by the cavity model. Using this equation, one can avoid hit and trial for getting simulated co-axial feed distance by knowing theoretically inset feed distance. A ratio also has been developed between co-axial probe feed and inset probe feed.
