The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum.
Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, K u, K, or K a band, or by similar NATO or EU designations.

Weather radar

Doppler weather radarradarDoppler radar
X band radar frequency sub-bands are used in civil, military, and government institutions for weather monitoring, air traffic control, maritime vessel traffic control, defense tracking, and vehicle speed detection for law enforcement.
3 cm X-band radar is used only for short-range units, and 1 cm Ka-band weather radar is used only for research on small-particle phenomena such as drizzle and fog.

Phased array

phased array radarphased-arrayphased-array radar
X band is used in radar applications including continuous-wave, pulsed, single-polarization, dual-polarization, synthetic aperture radar, and phased arrays.
The antenna, which uses the X band, used 26 radiative elements and can gracefully degrade.

Radar

X band radar frequency sub-bands are used in civil, military, and government institutions for weather monitoring, air traffic control, maritime vessel traffic control, defense tracking, and vehicle speed detection for law enforcement.
Modern radar speed guns normally operate at X, K, K a, and (in Europe) K u bands.

Goldstone Deep Space Communications Complex

GoldstoneGoldstone Deep Space NetworkGoldstone Observatory
DSN facilities are in Goldstone, California (in the Mojave Desert), near Canberra, Australia, and near Madrid, Spain.
The radio frequencies used for spacecraft communication are in the microwave part of the radio spectrum; S band (2.29 - 2.30 GHz), X band (8.40 - 8.50 GHz) and Ka band (31.8 - 32.3 GHz).

Curiosity (rover)

Notable deep space probe programs that have employed X band communications include the Viking Mars landers; the Voyager missions to Jupiter, Saturn, and beyond; the Galileo Jupiter orbiter; the New Horizons mission to Pluto and the Kuiper belt, the Curiosity rover and the Cassini-Huygens Saturn orbiter.
*Communications: Curiosity is equipped with significant telecommunication redundancy by several means – an X band transmitter and receiver that can communicate directly with Earth, and a UHF Electra-Lite software-defined radio for communicating with Mars orbiters.

Communication with the spacecraft is via X band.

Viking program

VikingViking missionsViking Orbiter
An important use of the X band communications came with the two Viking program landers.
An X band (8.4 GHz) downlink was also added specifically for radio science and to conduct communications experiments.

Communications satellite

The X band is used for radar, satellite communication, and wireless computer networks.
The landers use UHF transmitters to send their data to the orbiters, which then relay the data to Earth using either X band or Ka band frequencies.

Electron paramagnetic resonance

electron spin resonanceEPRESR
Many electron paramagnetic resonance (EPR) spectrometers operate near 9.8 GHz.
EPR experiments often are conducted at X and, less commonly, Q bands, mainly due to the ready availability of the necessary microwave components (which originally were developed for radar applications).

Compact Linear Collider

CLICCompact Linear Collider (CLIC)
The European X-band frequency is used for the Compact Linear Collider (CLIC).
X-band high-power klystron-based RF sources were built in stages at the high-gradient X-band test facility (XBOX), CERN, ). These facilities provide the RF power and infrastructure required for the conditioning and verification of the performance of CLIC accelerating structures, and other X-band based projects.
