I have a great understanding of today's need for most wireless communication technologies, and we are indeed in very challenging era in antenna design. A huge Demand for high capacity, high gain, and broad bandwidth. Besides this, what are other today's antennas design or say wireless communication challenges? Direct me to a good article or papers that I can refer to.
Thanks
I think the most demanding task for antenna design is in the conventional MIMO and in massive MIMO wireless mobile communication systems.
Other task which is also very demanding is the developing antennas for ultrawideband wireless biomedical sensors.

To overcome the drawbacks of metamaterial based antenna is a challenge in antenna designing techniques.
Adaptive antennas for cognitive radios... Same antenna need to provide wideband for spectrum sensing and adaptive narrow band antenna for signal transmission.. Biomedical antennas are also another good area...
I think it is designing electrically small antennas for wireless devices.
the most demanding for antenna design is to design small size antenna with high gain and wide band range.
hi there, well there are different issues in various fields.
1. Antenna design for massive MIMO in wireless industry.
2. Design of ultrawideband antennas for wireless applications.
3. integrating technology with medical applications is also always the hour of need. Design of Antennas which constitute for advanced sensors in the medical field applications.
4. Use of Evolutionary algorithms and design of smart antennas.
One of very required antennas is an ultrawide band antenna for breast cancer detection with very narrow beam. There is ultrawide band antennas but it is not highly directive: Article Enhancing Tumor Detection in IR-UWB Breast Cancer System
An other challenge is to suppress the near field interaction or coupling between nearby antennas in the MIMO of the mobile phone. Please see the paper:https://www.researchgate.net/publication/275335973_Design_of_a_Planar_MIMO_Antenna_for_LTE-Advanced

The most demanding requirement? The price!
- Make it cheap ...
- ... on FR4 (resp."FR4-compliant") ...
- ... mechanically robust ...
- ... (without sacrificing too much performance).
The most interesting applications are those where giant piece counts are targeted. And these always have extreme price tags - requiring to find a cheap solution that fits the bill and fulfils the requirements list.
Currently, some very nice and clever solutions (like a WiFi antenna from a single, stamped piece of sheet metal) can be seen - and a lot of scrap.
