BROADBAND ULTRA-SHORT WAVE VIBRATOR Russian patent published in 2011 - IPC H01Q9/00 

FIELD: physics, radio.

SUBSTANCE: invention relates to antenna engineering and is meant for use as a transceiving antenna together with broadband ultra-short wave radio stations. The ultra-short wave vibrator consists of a metal plate (MP) (1) placed vertically over the conducting surface (CS) (2), where the metal plate is in rhomb-shaped, whose height H satisfies the inequality H≥0.18λ_max, where λ_max is the greatest wavelength of the working range of the waves, and angle α = 60°-80° at its sharp corners. One of the sharp corners is connected to the centre conductor of a coaxial feeder (3), the screen cladding of which is connected to the CS (2). The blunt corners of the MP (1) are connected to conductors (4) of a capacitive load (CCL) which are curved and lie in the plane of the MP 1. Outer ends of the CCL are adjacent to the vertex of the MP 1.

EFFECT: reduction in height of the device without deterioration of matching quality.
