Seeking a little practical advice...

Both are good options. Any decision is taking a gamble but here is my 2 cents worth:

E&M FIELDS: Best choice if you hope to get a job where the job description includes any of the course topics you listed.

FEA: Probably more useful for most people since it "more directly" applies to electronics, thermal, vibration and many other things. Being more general it is probably less impressive sounding, but it is probably more generally useful.

NOTE: I said "more directly" above for a good reason. The more you learn the more you start to recognize that many things are "about the same". Kodak used to use a SPICE electronic circuit analysis package to develop new photographic chemicals. Electrical circuits can be simulated using mechanical components. Many other examples exist. So, E&M Fields has more in common with thermal and vibration that you would initially think. But, it might not be easy to get that point across in a job interview.

Wireless is a hot topic today in automation and process control--cellular, RF, satellite, Zigbee, Bluetooth and all those technologies. Companies are using wireless to transmit control signals, sensor readings, video monitoring systems, access controls, smartgrid meters, security intrusion alarms, and so on. Somebody who understands antenna design and applications would probably have a good chance of finding a job in an industrial company or an OEM. In fact, it's rapidly getting to the point where just about everything is wireless.

Stupid as it may sound, go for what interests you. Simple as that ...

Do one, get hired, get trained for the other if there's need. Jobs are so varied that there's no telling what you'll be working in post-graduation. Plus, almost no employers look at an undergrad's course list when recruiting ...

Good luck! DZ

Stick with EM, it seems you're comfortable with that. Plus everything is going wireless these days and they will all need antennas!

Key to career happiness :

1) Find what you love doing.

2) Find some company to pay you to do it.

When you get up in the morning looking forward to getting to work, you've made it. Good luck.

Have you considered PLC (Programmable Logic Controllers) or PAC (Process Automation Controllers), SCADA, etc. These topics will open far more jobs for you than either of the two current considerations.

When you are in high school, one pretty much has the knowledge that computers control the world. But once you learn electricity, engineering degree, hopefully not too much later in life, you figure out second only to computers, PLCs control everything electrical in the world.

Already he is wired and you made him more confused. Go for one sub which you love, depth knowledge will make every thing. and whatever be the course plc pac fe, there is a master course. so actually it not matters most except personally.

All these people telling you to pursue what you like are missing the boat: The job market for engineers is very tough right now. If, for example, you absolutely love auto racing and wanted to be a data acquisition and sensors specialist for Penske or Childress racing, you'd be looking for a job for YEARS! My nephew graduated in June, and he's still looking for anything--sales, service, design, manufacturing, but the job market is dead. So be practical--study something that is in demand, whether you like it or not. Since you like antenna design and wireless is hot, that seems to me to be the best bet. And learn Chinese, too--just enough to be polite and get around China when you go there.
