Saab - Military Antennas

Saab is a leading supplier of military antennas for Electronic Warfare (EW), Electronic Intelligence (ELINT), Electronic Support Measure (ESM) and Electronic Countermeasure (ECM) applications. Our military antennas come in a wide range of frequencies, from 20MHz to 40GHz.

We offer standard products as well as a design capability to develop and customise military antennas for specific user requirements. Our military antennas include wideband Log Periodic Dipole Array (LPDA), horn, spiral, blade, omnidirectional and Direction Finding (DF) antennas.

LOG PERIODIC DIPOLE ARRAY ANTENNAS

Saab's range of wideband LPDA military antennas includes:

• 20MHz to 3,000MHz LPDA antenna of ultra-compact design with inductive loading
• 80MHz to 600MHz, 1.5kW CW ruggedised LPDA antenna for helicopter use
• 80MHz to 1,300MHz quick-assembly LPDA antenna in carry bag
• 0.7GHz to 3GHz and 1GHz to 40GHz etched PCB LPDA antennas suitable for dish feeds
• A multiband 20MHz to 512MHz LPDA antenna developed for snowy conditions (sections can be used individually)

HORN ANTENNAS

Saab horn antennas for both receiving and high-power applications include:

• 9:1 bandwidth dual-ridged horn antennas (for example 2GHz to 18GHz)
• S-band and C-band telemetry horn antennas
• 0.8GHz to 2GHz, 2GHz to 4GHz and 4GHz to 10GHz high power (600W CW) ridged horn antennas
• High power, broadband slant 45° and meander-line polarisers
• 6GHz to 18GHz circularly polarised horn antennas with symmetrical or asymmetrical beam shapes

SPIRAL ANTENNAS

Our spiral antennas cover 150MHz to 40GHz, including 0.5GHz to 6GHz, 2GHz to 18GHz, 6GHz to 18GHz and 18GHz to 40GHz spirals with excellent axial ratio and squint performance for amplitude comparison DF systems.

Saab's precision spiral antennas present outstanding amplitude and phase-tracking performance for interferometric DF systems in various bands.

Also available are 0.7GHz to 40GHz spiral antennas, which are only 110mm in diameter and have an integrated 0.7GHz to 18GHz and 18GHz to 40GHz diplexer.

BLADE ANTENNAS

We also supply compact, lightweight, industry-standard footprint blades, for use on high-performance and commercial jet aircraft. These blade antennas include:

• 20MHz to 500MHz phase track sets of blade antennas for airborne VHF interferometric DF
• 225MHz to 500MHz high-power blades
• 500Mhz to 2,000MHz blades and L-band blades for airborne TACAN and IFF applications

OMNIDIRECTIONAL ANTENNAS

We supply biconical omnidirectional antennas with vertical, slant 45° or circular polarisation options in the 0.5GHz to 40GHz range. Slant 45° models are compact and are supplied in 0.5GHz to 3GHz, 1GHz to 8GHz, 2GHz to 18GHz and 18GHz to 40GHz bands.

STUB AND MONOPOLE ANTENNAS

Our biconical omnidirectional antennas are augmented by radome-enclosed stub and monopole antennas suitable for airborne use, covering 2GHz to 18GHz and 6GHz to 18GHz.

ANTENNA SYSTEMS

Saab provides fully integrated and tested antenna systems that employ our high-quality antennas, including:

• High-power jamming arrays for spatial power combining in the 0.8GHz to 2GHz, 2GHz to 4GHz and 4GHZ to 10GHz range, with integral phase and power monitors
• An integrated 0.7GHZ to 18GHz four-channel spiral DF assembly, including slant 45° omnidirectional stack
• A compact, low profile, slant 45° spinning DF assembly (785mm in diameter, 170mm high) covering 0.7GHz to 18GHz in three sub-bands – optional coverage to 40GHz
• A radome-enclosed spinning reflector DF antenna with integrated omni-stack covering 1GHz to 40GHz (optional coverage down to 0.5 GHz)
• Integrated assemblies of phase-matched spiral antennas for interferometric DF
