I am currently a master level technical leader in R&D.  I received my Bachelor of Engineering (Electronics and Communication) in 2001, and Master of Technology (Microwave Engineering) from Indian Institute of Technology (IIT-BHU), Varanasi in 2003. I worked 4 year as Scientist in Indian Space research organization (ISRO). I have more than 15 years experience in RF, Microwave, Signal Integrity and Power Integrity analysis for high speed systems and Antenna Design. My areas of interest are  RF, Microwave circuits, Antenna designs, Signal Integrity(SI), Power Integrity(PI) and EMI/EMC. I am reviewer for many international journals, such as IET, ACES and Antenna Journal and I have delivered invited talks in various conferences and institutions. I have more than 38 international and Nation research publications. I have 2 patents also in my name.

  1. please let me know how to give feeding to conformal patch antenna. I am having trouble in giving line feeding as well as coaxial feeding. Thank you

  2. Sir I want to know how to extract equivalent circuit of antenna .I am working on RFID tag antenna design….

  3. Hi,
    What would be the nominal Gain of a patch antenna on FR4 substrate. Is that possible to achieve the bandwidth of 100 MHz in an elemental patch.

      • Thanks for your reply. I tried to design patch antenna on FR4 substrate of 1.6mm thickness. I got the Gain of 2.2 dBi & Bandwidth of 52 MHz. But when I designed an array of 4×4 patches, I can able to achieve the bandwidth of 100 MHz and the gain is around 11 dBi. Why the gain is too low on FR4. Is there any theory relating the increase in the bandwidth to patch array structure

  4. 2.2 Gain is really low. If a signal patch antenna gain is 2.2 then an array of 4×4 should give max gain 14.2 dBi and you are getting 11 dBi that’s again 3 dBi less.. There are multiple ways to increase bandwidth of patch antenn

  5. I”m interested on corrugated horn design and I downloaded your Maltalb code but it’s protected that why I’m contacting you as you’ve said, in order to have the password.

    Thank you
