SMALL-SIZED STRIP ANTENNA OF THE VHF BAND Russian patent published in 2022 - IPC H01Q1/38 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering, namely to the field of aircraft antennas, and can be used in antenna-feeder devices of VHF bands as a small-sized transmitting or receiving antenna. Essence: the antenna is made in the form of three longitudinal conductive strips with dielectric substrates arranged on top of each other on a conductive screen. The lower strip (the first one), closest to the screen, has an electrical contact with the central conductor feeding the input of the HF connector of the coaxial cable. The middle strip (the second one) has an electrical contact with a conductive screen. The upper (third) strip has an electrical contact with the lower one, bypassing the middle strip, through a hole in it by means of a connecting bolt.

EFFECT: providing a significant reduction in the length of the antenna and simplifying the process of adjusting the antenna alignment by changing the length of the upper easily accessible strip, which plays the role of a non-dissipative stub.
