Abstract: A contiguous radiating ring antenna structure suitable for a vehicle is disclosed. The antenna structure comprises a curved shape structure having a plurality of radiating rings, a plurality of sectors, a connecting unit, and a plurality of frequency barriers. The antenna structure has a phase variation of less than 2° degrees over 360° of azimuth coverage and about +/?85° of elevation coverage. The antenna structure has a thickness of less than 0.5 inches. The contiguous radiating ring antenna structure is design for demanding vehicular applications, including missiles, rockets, and aircraft. The contiguous radiating annular ring antenna comprises a beam forming network, which is configured to be incorporated into a printed antenna board for enhancing the vehicular communications.

Abstract: A deployable manpack antenna assembly comprises a transceiver antenna unit, a first support rod, a flexible conduit connector, a second support rod, a base unit, a latching unit, a clamping unit, and at least two sleeve retainer stops. The deployable manpack antenna assembly is configured for use in military applications, particularly relating to ground-party communications systems intended to be used in both communications-at-the-halt (CATH) and communications-on-the-move (COTM). The manpack antenna assembly operates in Ku, K and Ka bands for soldiers in the battlefield. The manpack antenna assembly comprises one of the two antennas, a biconical variant antenna, or an inverted-F variant antenna, both of which operate at Ku-band, K-band, and Ka-band simultaneously.

Abstract: A multi-band ground antenna with a nested concentric coaxial feed assembly is disclosed for supporting multiple frequency bands. The nested concentric coaxial feed assembly is attached to an antenna reflector through an attachment unit. The nested concentric coaxial feed assembly is located at a reflector focal point. The nested concentric coaxial feed assembly comprises an elongated housing, a feed cone, and a sub-reflector. The nested concentric coaxial feed assembly operates seamlessly across a wider bandwidth, without any gaps or performance drops. The multi-band ground antenna with multiple bands is being introduced for ground communications. The multi-band ground antenna comprises a nested concentric coaxial feed assembly, which supports a wide range of frequencies varies between 2 GHz and 36 GHz. The multi-band ground antenna is designed to be used in satellites and aircraft.
