Special Issue Information
Dear Colleagues,
In the last 10 years, satellite communication systems have evolved towards constellations with many satellites (hundreds and thousands) and small satellites orbiting in a large variety of orbits at different altitudes, while still using the huge geostationary satellites in the Clarke Orbit. The growing capacity offered by all these systems is possible because higher frequency bands are adopted, such as the Ka band (20 and 30 GHz). Now, the higher Q/V frequency bands (33–75 GHz) are also becoming the focus of experiments. At these frequencies, smaller and lighter equipment (antennae and receivers/transmitters) allows a widespread use around the globe, both for fixed and mobile users. However, at these frequencies, the fading due to the troposphere (water vapor, oxygen, rainfall, snow) is the limiting factor. Modulation, coding, and fade countermeasures are being studied to overcome some of these difficulties.
This Special Issue is directed at industrial and academic colleagues who should address the basic aspects of satellite communication at these high frequencies. Some of these topics are also of interest for future Mars missions. The potential topics include but are not limited to the following research areas:
- Orbits and constellations for global communications;
- Small satellites;
- Propagation effects at Ka and Q/V frequency bands for mobile, broadcast, navigation, and fixed services;
- Fade countermeasures;
- Global satellite communication for the planet Mars.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Information is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
