Group2 in the class on Thursday morning
I'm a student from electronic engineering college and my career is related to array antenna,I think I will become a senior RF antenna engineer in the future.My career is a promising industry refers to a lot of necessary things in our common life which will benefit the society a lot and let me find some examples.
First of all,look at the cellphones in your hands,if you want to send short messages or make a phone call to others,you will never neglect the importance of antennas.Antennas in the cellphone ensure the receiving and transmission of the voice signal.For bigger application,antennas are widely used in radars,if you want to use radar to detect the position or azimuth or some other information of the testing factor,you can't make it without the help of antennas.According to Wikipedia,"An electronically scanned array (ESA), or a phased array, offers advantages over mechanically scanned antennas such as instantaneous beam scanning, the availability of multiple concurrent agile beams, and concurrently operating radar modes. Antennas also play an important role in television.Everybody enjoys watching TV cozily at home,however,without the help of antennas,you can't receive any program at all.According to Wikipedia,"As discussed previously, antennas may be placed indoors where signals are strong enough to overcome antenna shortcomings. The antenna is simply plugged into the television receiver and placed conveniently, often on the top of the receiver ("set-top")."Antennas exist everywhere in our common life,we won't
notice them when we use them,however,if we lose antennas,we will realize the importance of them.
Besides applying in common electrical equipment,antennas also benefit the society in many other ways.Firstly,because of antennas,people use cellphones to send messages instead of writing letters.And when we use less letters,we cut less trees,and the less we cut trees,the better our environment will be.So antennas make contribution to our environment.Secondly,nowadays,there comes a new technology which use radar to predict the earthquake.It is known to us all that earthquake is a natural disaster which can't be avoided and will bring us a huge damage.However,when we have the technology to use radar to predict it,things change,we can save millions of lives,we can protect lots of trees,we can reduce the loss of our property.So antennas also help a lot to protect our personal safety.Thirdly,nowadays,we can use television to shopping instead of traditional ways.It is interesting and convenient to buy things through television,it is much cheaper and will save us a lot of time.We just watch the advertisement on the TV and if we want to buy it,we can make a phone call to the seller.It is truly a innovative way of shopping.So antennas can also make our life much more convenient and interesting.
There are still many ways which antennas benefit the society.So in my opinion,my career is a promising industry benefits the society a lot.I hope that my career will have a bright prospect and will become much more useful in the future.
