Transactions on Maritime Science, 2015 This paper describes the building and testing of a 2.4 GHz antenna which can be used for WLAN as well as for other purposes. The antenna was built to have highest gain at 2.4 GHz although it can be used from frequency of 1.7 GHz up to 2.6 GHz. The paper also describes the calculation of the antenna parameters and dimensions as well as the measurements ...

MXene‐Coated 3D Printed Horn Antennas for Ku Frequency Band
Advanced Materials Technologies, EarlyView.An additive manufacturing approach to 3D printing horn antennas and coating them with Ti3C2Tx MXene is proposed. Rapid fabrication of lightweight, high‐performance antennas operating in the Ku‐band (12.4–18 GHz) has been demonstrated. The MXene‐coated antennas exhibit comparable electromagnetic performance to conventional, costly aluminum ones, with ...

Measurement-Based Characterization of 15 GHz Propagation Channels in a Laboratory Environment
IEEE Access, 2017 In this paper, measurements in a laboratory characterizing the 15-GHz band propagation channels are introduced. Both an omnidirectional antenna (ODA) and a 10° half-power-beamwidth (HPBW) pyramidal horn antenna are deployed at the transmitter (Tx)

Collapsible corrugated horn antenna [PDF]
, 1978 A horn antenna that is readily collapsible while not in use is described. A number of different sized annular metal rings are arranged in a sequence such that each ring is larger than the one that precedes it in the sequence.
