Fascinating Antennas, Part 1

#antennas #communications #electronics #PDH #CEU #LICN #military #aircraft #avionics

Brought to you by the IEEE Consultants Network of Long Island (LICN)

In Part 1 of our two part series on antennas, we will focus on "Electrically or Mechanically Commutated Arrays".

We see antennas everywhere. Every car radio, every police radio, many televisions and every smartphone has antennas. These antennas all provide a specific service – to insert information into the environment and extract it some distance away. Antennas provide the pure realization of Action at a Distance.

However, some systems used for air traffic control and navigation, combat control, and even communication with satellites and the stars (radio astronomy) put incredible requirements on their antennas. Such antennas are mind-bogglingly complicated to the uneducated, but they can be conceptually broken down into bite-size-chunks to tell a fascinating story.

Here we will discuss several such systems such as keeping airliners safe, assisting civil and military aircraft to land all-weather, protecting military assets from kinetic attack, and the staggering requirements inherent in communicating with orbiting platforms and even travelling through the galaxy (two have left the solar system)


  Date and Time




  • Date: 07 Dec 2023
  • Time: 07:00 PM to 09:30 PM
  • All times are (UTC-05:00) Eastern Time (US & Canada)

Online event (via Zoom): Please register on meetup.com to obtain the Zoom link.

There is no cost to attend this meeting, however, if you would like to receive Continuing Education Units (0.2 CEUs/2 PDHs) then payment of a $10 fee is required. You will also have to properly fill out an Evaluation Form to prove that you attended this lecture. Click here to open the PDF form. Download it to your local drive (look for the download button in upper right tool bar) and fill it out (the form can be filled in with most PDF readers). Save the form and email it to ambertec@ieee.org.

We accept electronic payment via Zelle. Zelle is a bank-to-bank transfer mechanism supported by most banks, without a fee, as part of their normal online banking capabilities. There is also a Zelle app available for your smartphone.

When you use Zelle with your bank, it will ask for the following information: 1) the amount to send (enter $10.00), 2) what account you want to pull the money from (select whatever account you want to use), and 3) the phone number or email of the recipient (enter ieeelicn@gmail.com. Don’t worry if you see the name of our Treasurer, David Rost, pop up). If it asks for a memo field, we suggest entering "yymmdd LICN CEU” where yymmdd are the year, month and date of the lecture.

While we prefer that your payment and evaluation form are received by the day of the lecture, they must be received by the first Monday after the lecture.

If paying by Zelle is a problem for you, then please contact John Dunn at ambertec@ieee.org for an alternate payment method.

Ed Gellender


Fascinating Antennas

Ed Gellender never grew up, and uses a lifetime accumulation of academic and experience credentials to continue playing with a succession of the biggest and best toys you have ever seen (Ever bounce off a runway? Ever play chicken with a freight train in a blizzard?).

Ed was working on the railroad all the day long, specifically on trackside thermal and acoustic detection of “hotboxes,” with their associated axle counting sensors, for which he holds a US patent. He also has experience with trackside consist monitoring, automatic train control (ATCS), positive train control (PTC) and onboard status monitoring.

Ed has also worked on a wide variety of aviation and shipboard electronic systems including Radios, Radars, aircraft landing systems, and even weather balloons. Recently, Ed was the cognizant engineer for the APX-122 IFF interrogator on the Navy’s new E-2D radar plane, notably flight testing anti-fratricide combat ID (“Mode 5”).

Ed has also worked on high power electrical distribution networks all around the New York City Metropolitan area with Con Edison, and also on power distribution on the George Washington, Verrazano, and Triboro Bridges, and Midtown Tunnel.


Howard Hausman received his MSEE degree from Polytechnic University/Tandon School of Engineering, NYU where he was an Adjunct Professor.  He is currently President/CEO of RF Microwave Consulting Services and an Adjunct Professor at Hofstra Universit and Adjunct Associated Professor at NYIT Adjunct Associated Professor at NYIT. 

Formerly Mr. Hausman was CTO and VP of Engineering, before being appointed President/CEO of MITEQ Inc., a world renown microwave engineering company with approximately 500 employees.  He has designed hardware, wrote papers, and lectured on microwave systems and components for Satellite Communications, Space Systems, Radar and Reconnaissance systems.

Howard Hausman is a recipient of an NYU Distinguished Alumni Award, the IEEE LI Alex Gruenwald Award “For outstanding contributions to enhance the knowledge of the IEEE LI Section members”, and a NASA Award for work on the Mars Landing System. 

Mr. Hausman is currently the Chairman of the IEEE LI Communications Society and was awarded a patent “Measuring Satellite Linearity from Earth Using a Low Duty Cycle Pulsed Microwave Signal”.  He also authored a textbook “Microwave Power Amplifier Design with MMIC Modules” published by Artech House.
