Overview
JK B 41 is an airborne biconical antenna with a stand off mast, large bandwidth. It operates in the frequency range of 18 to 40 GHz. The ESM antenna subsystem employs a biconical antenna covering 18-40 GHz. The antenna is fed by a custom built K female connector with extended center conductor which is connected to the top cone of the antenna. A four layer slant linear polariser circuit is used to make the antenna slant linearly polarised to respond to all polariza?ons viz., VP, HP, slant 45 ? (left or right) and circular (RHCP, LHCP). An overall ‘C’ sandwich Radome is used and firmly integrated with antenna to protect the antenna from external environment.
