Hi, 188.193.103.199. On your recent additions to the article: this is not the appropriate place for this content. An "array antenna" is not the same as a "phased array". Read the introduction. An array antenna is any antenna composed of multiple antennas working together. A phased array is a specialized array antenna with phase shifters, allowing the beam to be steered. Here are some sources supporting these definitions: p.102, p.303, p.315, p.128, p.485, p.xi, p.30. We have a separate article about Phased arrays.
Also, the last sentence, on patents, is a little confusing. Your English is a little ungrammatical. Can you make it clearer? --ChetvornoTALK 18:52, 28 April 2021 (UTC)
- 188.193.103.199, here are the problems I have with your addition to the introduction:
- "...and space applications..." - Space communication didn't begin until the 1960s. Arrays were in use by the 1920s.
- "...phased arrays later found its way into communication (under the names "smart antenna" or "MIMO system") as well." - this implies that the previous sentence was only about phased arrays. This introduction is about general array antennas. We have a separate article for phased arrays.
- "Since several decades, they are in use for navigation purposes as well." - Insufficiently specific. What does this refer to? Phased arrays? This introduction is about general array antennas. Navigation array antennas have been in use for more than "several decades"; the aircraft navigation system VOR used sophisticated array antennas beginning 1937, and radio direction finding (RDF) radiogoniometer arrays were used from 1912.
- "They enable the computation of the arrays attitude, which is also used for at least one decade now." - This is confusing. An array's "attitude" doesn't need to be computed, it can be measured at the antenna. It also seems to be about phased arrays. This introduction is about general array antennas.
- "Still there are some patents granted, which are, however, due to the large body of knowledge published before and the generic structure of the receiver (that makes it very hard to achieve a real add-on) of only very little if no value." - The English is so bad that I am not sure what you are saying. If you mean that most array antenna information is in the public domain, that is probably true, but why is this WP:notable? I doubt that this is preventing new array research and development. If that is what you are saying, you need to support it with a citation from a WP:reliable source (see WP:VERIFIABILITY).
- The introduction should be no more than 4 paragraphs(MOS:LEAD). This intro is already very lengthy, history should probably go in a history section in the body.
- I agree the article needs some history, but it must be accurate and should be supported by citations to reliable sources.

Why don't you merge these findings in the article?188.193.103.199 (talk) 15:40, 1 May 2021 (UTC)
