Embodiments generally disclosed herein relate to a sub-wavelength multi-port codesign approach between the unit transceiver element and the integrated EM interface to enable a generalized broadband MIMO array with individually programmable element patterns. The co-design approach allows processing of radiated signals at the antenna level distinct from classical arrays. The transmitter and receiver architectures with the integrated EM interface are implemented in 65-nm CMOS and have a bandwidth of 37-73 GHz. Wireless links with data rates up to 12 Gb/s are demonstrated across the spectrum with a wide range of reconfigurability of the active EM interface. The multifunctional EM interface and the broadband transceivers can enable future efficient and compact MIMO arrays for reliable links exploiting frequency, spatial, pattern and polarization diversities.

An outer space deployable antenna may include a support shaft, a plurality of antenna fins, and an actuator. At least one draw cord may be coupled between the antenna fins and the actuator so that the antenna fins are moveable from a flat stored configuration to a fanned-out deployed configuration surrounding the support shaft.
