The present disclosure describes monopole platform assembly. The platform assembly includes a frame, the frame including an elongate, hollow main support member of rectangular cross-section, and a plurality of elongate, hollow auxiliary support members of rectangular cross-section attached orthogonally to the main support member; a mounting plate coupled to an end of the main support member; at least two grating edge members coupled to the auxiliary support members; and a grating, the grating being supported by the two grating edge members, the auxiliary support members, and the main support member. The opposing ends of each auxiliary support member extend a distance outwardly passed the grating edge members such that the extended ends of the auxiliary support members are positioned to support a horizontal pipe member. The extended ends of the auxiliary support members each include a feature configured to enable fixing of the horizontal pipe member thereto. Additional platform assemblies are described herein.

A compact mobile high-frequency Antenna that quickly and quietly self-adjusts to minimize Voltage Standing Wave Ratio (VSWR). Includes a compact tuning coil and a rolling contact. A Reentrant cap serves as a capacitive top hat. A spiral cut enhances the efficiency is this very short antenna. A tough insulating tube covers the antenna to serve as a radome protect the user from RF burns. The use of rolling contacts on a smooth inside diameter of the tuning coil greatly reduces the force to move the contactor as well as the acoustical noise generated when tuning. A controller drives a servo motor to position the contactor to the optimal position within the tuning coil and selects the impedance to connect between the unused end of the tuning coil and the feed point of the antenna to optimize VSWR.

In various embodiments, disclosed herein are systems and methods directed to the fabrication of a coreless semiconductor package (e.g., a millimeter (mm)-wave antenna package) having an asymmetric build-up layer count that can be fabricated on both sides of a temporary substrate (e.g., a core). The asymmetric build-up layer count can reduce the overall layer count in the fabrication of the semiconductor package and can therefore contribute to fabrication cost reduction. In further embodiments, the semiconductor package (e.g., a millimeter (mm)-wave antenna packages) can further comprise dummification elements disposed near one or more antenna layers. Further, the dummification elements disposed near one or more antenna layers can reduce image current and thereby increasing the antenna gain and efficiency.
