Multi-frequency conformal antenna with headspace null and its working method

Abstract

The invention provides a multi-frequency conformal antenna with a headspace null point and a working method, which include, from top to bottom: a dielectric resonator, a floor, a dielectric substrate, and a feeder at the bottom of the dielectric substrate; both the floor and the dielectric resonator are arc-shaped and Conformal, the center of the arc is located below the arc, the dielectric resonator is fixed in the middle of the floor, and the floor material is metal; the upper and lower surfaces of the dielectric substrate are respectively fitted to cover the floor and the feeder; the feeder seam is etched in the center of the floor; this By analyzing the internal field distribution and structure of the antenna, the invention constructs the antenna radiation model with magnetic dipoles, and realizes dual-frequency point operation through two high-order resonance modes. By adopting a convex floor and a convex dielectric resonator, the dielectric The two even-order high-order modes of the resonator antenna realize oblique omnidirectional and side-firing zero-point performance, which can meet the requirements of interference suppression and electromagnetic compatibility. The antenna adopts side feed and is coupled through the floor slot to achieve a low profile structure.

Description

technical field [0001] The invention belongs to the technical field of conformal dielectric resonator antennas, in particular to a multi-frequency conformal antenna with a headspace zero point and a working method thereof. Background technique [0002] In recent years, with the rapid update and iteration of wireless communication technology and integrated circuit technology, various military and civilian wireless communication equipment are also developing in the direction of high sensitivity, high integration, broadband, and miniaturization. In this context, higher requirements are put forward for antenna performance, and indicators such as multi-band, miniaturization, and easy integration with the system have become important considerations in antenna design. In addition, antennas are also required to have a conformal structure on high-speed aircraft such as airplanes and missiles, and wearable devices. These more stringent technical requirements have prompted us to gradu...
