VOR/LOC antennas operating in the VHF band from 108-118 MHz are installed on helicopter tail booms. Recently I've seen an older antenna design realized as medium sized half loops of length below one wavelength. These antennas are installed in pairs on each side of helicopter tail booms and excited 180 degree out of phase. Matching these antennas can be challenge but EM simulation with #CSTStudioSuite from #Simulia can help to solve this problem. Even more the EM simulation provides more inside offering access to surface currents, EM fields and far field pattern. As can be seen the installed two VOR/LOC antennas on an elliptical platform show maximum directivity along platform axis which would also be the forward direction of a helicopter.

Protocols - 4G RAN 🔹 RRC (L3) – The RRC protocol manages the control plane, handling signaling between the UE (User Equipment) and the network. The major functions of the RRC protocol include connection establishment/release functions, broadcast of system information, radio bearer establishment, mobility procedures, paging notification and outer loop power control. 🔹PDCP (L2) - It deals with higher-layer data, ensuring efficient transmission through header compression and encryption. It transfers user plane & control plane data. 🔹RLC (L2)– The RLC protocol ensures reliable data transfer. With ARQ (Automatic Repeat Request), it detects errors in data transmission and triggers retransmissions, ensuring that any corrupted or lost data is resent 🔹MAC (L2) – Medium Access Control is responsible for logical channel multiplexing, hybrid automatic repeat request (HARQ), uplink/downlink scheduling, random access procedure, and maintenance of uplink timing. 🔹PHY layer (L1) handles crucial tasks like IFFT (Inverse Fast Fourier Transform), modulation, coding, and rate matching. It contains different channels- - Physical Broadcast Channel (PBCH), which carries part of the system information (MIB) required by the UE to access the network; Primary and Secondary Synchronization Signals (PSS & SSS) for cell-search procedures and cell identification; - Physical control format indicator channel (PCFICH) to carry the number of OFDM symbols used for transmission of PDCCHs in a subframe; - Physical Hybrid Automatic request (HARQ) indicator (PHICH) to send ACK/NACK feedback to the UE for the uplink blocks received by eNB; Physical data shared channel (PDSCH) to carry user data, paging info & SIB msgs.
