Guidance on Antenna Design

  1. Apr 15, 2012 #1
    Hi

    I have taken a very rudimentary course on antenna theory, now i am interested in further deepening my knowledge. I have bought myself Balanis's book on antenna theory, I need some guidance regarding what chapters should i study as it is quite a large book.

    Secondly, after i have got enough of theory i would like to design antennas using HFSS (possibly patch antennas), now my question is, what is the next step after getting the 3D rad pattern, vswr, impedance etc in HFSS and fabricating the antenna?? How to test the antenna physically?? Will i have to construct a transmitter and receiver for the antenna???? What is the standard practice to test the antenna in the academia?

    I suspect that you should be guided by the author of the expensive book and start it from the beginning.
    You have probably already sped through it and looked at the nice graphs, but it is time to get serious and cover the theory.

    There are some wonderful simulators available for computers and these can display the properties of antennas if you feed in the dimensions of the antenna and give it a frequency.

    One I like and use is EZNEC which is available as a free working demo and this is perfect for simple antennas.
    The commercial versions you pay for cover more complex structures and these are still pretty reasonably priced. But try the demo first.

    Forget patch antennas for a few years until you get comfortable with lower frequency antennas.

    I have been studying antenna at the end of two EM books and beginning few chapters of Balanis until I got involved in some music electronics projects and had to stop half a year ago. So I am not an expert by any stretch.

    You need to study at least the first 5 chapters to get going. Then the aperture antenna as the basic fundamental knowledge. Now a days, seem like a lot of designs are on pcb type of patch antenna, microstrip type, most of the jobs are on those. So I would think these are more useful in finding jobs. That's the direction I am heading at least as the first step after I finish the 6 essential chapters.

    Remember most of the wireless connections are based around 2.4GHz eg. 802.11, Blue Tooth etc. Look at those as an example of what is important for the job market. That's the path I am heading when I get back to it. Then the others come next.
