Abstract

The invention discloses a holographic modulation based artificial tensor impedance surfaced antenna and an implementation method thereof. The artificial tensor impedance surfaced antenna systematically comprises an artificial tensor impendance surface composed of multiple unit lattices equal in size; each unit lattice sequentially comprises a metal floor, a dielectric substrate and a metal paster from top to bottom; surface impedance corresponding to the unit lattices of the artificial tensor impedance surface is controlled through geometric parameters of the metal paster, so that the surface impedance on the surface of the antenna is distributed according to holographic interference pattern rules of a source field and a target field. The implementation method includes the steps of S1, scalar impedance extraction and simulation; 2), matching of equivalent scalar surface impedance curves; S3, holographic modulation of the sensor surface impedance; S4, antenna modeling and simulation. The target radiation field of a specific planning mode is obtained by the aid of the holographic tensor surface impedance principle, an equivalent scalar surface impedance matching criterion is put forward, and data volume needed in modulation of the tensor surface impedance is effectively reduced.

Description

technical field [0001] The invention relates to an artificial tensor impedance surface antenna based on holographic modulation and a realization method thereof. Background technique [0002] With the vigorous development of wireless communication technology today, various wireless communication applications have been fully integrated into people's daily life and become an indispensable part. In the military field, the antenna system represented by radar also plays a vital role in the combat capability of the army. As the core component of sending and receiving electromagnetic waves, the electromagnetic performance and physical characteristics of the antenna are crucial to the entire wireless communication system. Taking the fighter airborne antenna as an example, in addition to high or specific requirements on traditional antenna indicators such as antenna gain and polarization, the antenna also needs to have characteristics such as low profile, easy conformal integration, ...
