Please I Need Help On A Project by Edisa(m): 10:21am On Jul 10, 2020
Before the lockdown brohaha,our project supervisor asked us(student) to come up with possible trainers that can be developed to help students in their practicals. The suggested trainers will serve as our project,so me decided to think outside the box( i no no say na whahala i put maself so) and i came up with the idea of developing an antenna trainer.i suggested the topic to our supervisor and he agreed and asked me to go research on it but the problem na be say,me way suggest the topic,i have little or no idea on how to go about it so,i need your help.
The antenna trainer will consist of a transmitter and a reciever unit,differernt type of transmitting and recieving antennas(e,g yalgi,dipole e.t.c).
The purpose or idea behind the trainer,is to expose students to experiment such as
* pathloss experiements using different antennas
* plotting radiation patterns of different antennas.
The problem now is, i dont know how am gonna get the losses in decibel at the recieving antenna for different antennna.i intended using the free space pathloss formular( 20 log(4piFd/C)) but i discovered that all the antennas with have the same losses.
The second problem is getting the radiation pattern.is there any software that can be use for achieving this?
I realy need your help on this,dont knw if i posted on the right section.

u can use any of the antenna type base on these features lengh,bandwidth,gain and frequency of operation.the most important of this is frequency of operation.concerning the issue of losses there is no way you would transmit signal without losses because we do not have a perfect space you can do that by using the appropriate formular in decibel..........concerning the issue of pattern of radiation,one of characteristics of an antenna is called directivity.directivity is the way you want your antenna to rotate about fixed axis.we have isotropic radiation which is the most widely used of all types of directivity because it rotate within and beyond the surroundings...in conclusion your project involve two stages 1 transmittting station 2 receiving station which will be Couple together by a coupling capacitor....modulation will take place at the transmitter while demodulation takes place at receiver....of course u need a software applicatiion to carry out this at the transmitter u need oscillator majorly colpit,mixer,mic and at the receiver u need diode rectifier to demodulate then loud speaker as ur output all this should be on a 5v board
