1. An antenna for transmitting or receiving radiation having a wavelength λ
- comprising;
a first conductor having a side thereof concavely curved with respect to a plane;
a second conductor, disposed directly on an opposite side of said plane and having a side concavely curved with respect to said plane such that the concave sides of said first and second conductors face each other, said second conductor having a length substantially equal to the length of said first conductor, said first and second conductors being separated by a gap coincident with said plane to thereby define a capacitance;
an inductor coupled to at least one of said first and second conductors and connected to form an LC resonance circuit with said first and second conductors; and
wherein said first and second conductors have a length of approximately λ
/4 or less at a resonant frequency of said LC resonant circuit.

Abstract
An antenna for detecting or transmitting polarized radiation. The antenna is small in size (i.e., less than one quarter the wavelength of radiation at its resonant frequency) and is formed by a split-cylindrical capacitor which comprises of a pair of curved plate conductors which are curved about an axis of rotation centered on a plane which coincides with the direction of propagation of the polarized radiation. The curved plate conductors are disposed on opposite sides of the plane, facing each other and are separated by a gap through which the plane extends.
