BROADBAND ANTENNA Russian patent published in 2024 - IPC H01Q9/18 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, namely to antennae, and can be used as part of a panoramic detector-direction finder located on small-sized mobile platforms, for example, on board an unmanned aerial vehicle (UAV). Antenna comprises a vertical rectangular dipole with a four-leafed coupling element, which are conductive polygons electrically connected to each other by means of transition holes, formed on opposite sides of the foil dielectric, output of the communication element is connected to the input of the receiving device with input resistance of 50 Ohm through series-connected coplanar line and switch of subbands of antenna operation. Switch, in its turn, is formed by back-to-back first and second microwave switches, which form two signal transmission channels, the first of which includes an attenuator, and the second - source repeater. Due to the specified design of the antenna, a significant expansion of the operating frequency range of the device is achieved.

EFFECT: wider operating range of antenna frequencies with simultaneous reduction of weight and dimensions of the panoramic detector-direction finder as a whole.
