P-DaHGR Antenna

The P-DaHGR, or Pantograph-Deployable High-Gain Reflectarray, uses the same lightweight, flexible membranes as the T-DaHGR but tension is created using a pantograph hoop. Decoupling the membrane tension from the structural loads enables a smaller stowed envelope at the expense of higher deployed inertia compared to T-DaHGR.

T-DaHGR Antenna

The T-DaHGR, or Tape-Deployable High-Gain Reflectarray, uses tape springs to tension the membranes and react structural loads. This large, spacefed reflectarray enables large apertures with low deployed inertia, and can be configured to support wider bandwidth than traditional reflectarrays.


This antenna configuration deploys a mosaic of rigid elements to form unique antenna apertures and support higher frequencies than might be supported by membrane-based DaHGR systems. MMA is currently developing a high aspect ratio (>4:1) 4 sq. meter aperture antenna that stows in a 27U form factor. This technology also holds the potential of a deployed multi-functional structure (solar array + antenna).

Log Periodic Membrane Antenna

The deployable Log Periodic (DLP) antenna is a broadband antenna that packages for platforms as small as CubeSats with > 6dBi of gain. This small antenna can support frequencies from 350 MHz to 2 GHz or more, while stowing as small as 1U of volume. Larger systems can support frequencies down to 100 MHz and lower.

The deployable Log Periodic Membrane Array (LPMA) antenna consists of four membrane gores. Eliminating the lower frequency range dramatically reduces the deployed surface area. Slightly larger satellite platforms with increased attitude control capabilities may choose to take advantage of the increased gain offered by the LPMA in the 120 MHz – 300 MHz band.

Both approaches target reliability and performance, while minimizing size, weight, and cost. The log periodic radiating structure not only meets the VHF band requirement, but holds the potential for significant bandwidth.

Broadband Crossed Dipole Membrane Antenna (BCMA)

The Broadband Crossed Dipole Membrane Antenna (“BCMA”) creates a constrained feed, dual-polarization VHF antenna using two deployed planar membranes, an active layer and a ground-plane layer. This approach creates a planar aperture of roughly 94cm x 94cm, or half wavelength per side. The proposed antenna will stow within a 10 cm cubic (1U) form factor to support CubeSat applications, and satisfy the proposed requirements.

To accomplish this high compaction ratio, the architecture takes advantage of MMA technologies such as high-strain composite booms, tensioned thin-film membranes, and low-profile launch restraints. While fundamentally broadband in nature, the BCMA is nominally targeting the frequencies of 137 MHz and 255 MHz to address VHF/P dual-band. The crossed dipole’s dual polarization leverages MMA’s ongoing R&D technologies into an innovative system architecture to satisfy mission needs. By sizing the BCMA to fit in a 1U (10cm x 10cm x 10cm) volume, MMA is enabling cubesat and nanosats to achieve performance previously only possible through larger spacecraft. On this model, far-field simulations were completed and showed that the directivity of the BCMA exceeds the specified 0 dBi gain level and reaches 1.26 dBi and 4.72 dBi at 137 MHz and 255 MHz, respectively, with the 0.9 m² aperture.

V/W Band Rigid Antenna

MMA rigid antenna systems are designed to meet the exacting requirements of high frequency applications requiring parabolic reflectors. These antennas are designed to meet the growing demand for bandwidth as satellite communications systems expand into higher frequencies. This design supports up to 19 simultaneous beams, is 1 meter in diameter and supports frequencies up to 100 GHz for SATCOM space payloads.

These are just a handful of the antenna architectures we have designed to solve our customer’s mission requirements. Like all of our innovative solutions, each mission is unique and requires a unique approach. We collaborate with our customers and partners to determine the best solutions for your mission constraints, requirements and goals.  And we do this with agility, creativity, and reliability.

Magical Membranes

Traditional antennas don’t lend themselves to a broad range of storage options. Not only does the size of an antenna you have on a satellite dictate the size of antenna you need on the ground to receive information, but it drives the size (and cost!) of the launch vehicle you need to get it to space.

The magic behind many of our revolutionary RF solutions is the flexibility of our membrane innovations. Our membrane antennas offer significant advantages in compaction, simplicity, scalability and cost. They support single frequency, multi- or broadband applications and can generate different beam footprints.

Packaging flexibility. Mission flexibility. infinite POSSIBILITIES.
