Ask Harlan: Question of the Month - February 2007
Published February 7, 2007
In an effort to better combine the editorial content of our magazine with our newly developed and retooled on-line presence, we have decided to expand Harlan's RF and microwave engineering advice into a monthly feature that appears in Microwave Journal.
Harlan has selected one question from his "Ask Harlan" column to be featured in the January issue. Harlan will be monitoring the responses and will ultimately choose the best answer to the question. Although all of the responses to the featured question will be posted on our web site, we plan to publish the winning answer in the April issue.
You be the expert: Please take a few moments and provide an answer to this month's featured question. Good luck and we look forward to reviewing your answer.
All responses must be submitted by March 6, 2007, to be eligible for the participation of the February question.
Peter Saul from Saul Research has submitted this month's question:
What happened to the "Hula Hoop" antenna, AKA DDRR? It was reported in the 1960s, but not since. It appears from the references (Microwave Journal, Vol. 6, No. 11, November 1963, pp. 89-90; how can I get a copy?) to have had lots of promise.
The winning response will win a free book from Artech House, along with an "I Asked Harlan!" t-shirt. In addition, everyone who submits a legitimate response will be sent an "I Asked Harlan!" t-shirt.
If your response is selected as the winner, you'll receive a free book of your choice from Artech House. Visit the Artech House on-line bookstore at www.artechhouse.com for details on hundreds of professional-level books in microwave engineering and related areas (maximum prize retail value $150).
