Oh my. I just got mis-credited with sarcastic humor. I’m not saying that
intemperate expressions never appear on this list, but on the whole, the level
of civilization is quite high. Especially compared with many politicians and TV
personalities.

Antenna technology has not changed that much compared to circuit technology.
Looking like and being a fool are two different things.

Nothing new about those antennas though they have been around forever.
What has changed is the frequency things operate at going to higher
bands all the time.

How much has the GPS 1475.42 MHz (-relativity effects) frequency
changed since the 20th Century ?
And show me the GPS antenna the size of a grain of rice from that
period.
I know that ABM Phased array antennas are pre 1970's, What I am saying
is you don't see that on a cellphone -- yet.
Sure, Tesla and others played around with UWB transmission, so I guess
a high gain UWB antenna design isn't much interest to anyone today ?

Good God, we are here to talk about Rockets. In many ways the heyday
of rocket technology may have been in the past, but right here people
are making advancements. I laugh when I hear that NASA has built the
first 3D printed rocket component. Gee- where have I heard that before !
Poo poo technical development, and you look like a fool.
STOP IT !
