Abstract
The invention provides a new, small-size, wide-band gap electromagnetic band gap structural material, and the manufacturing method prints special metal pattern on microwave medium material plate by PCB process, where the size of the pattern is determined according to the applied frequency range. The electromagnetic band gap structural material can be used in antennas, filters, resonators, and other microwave devices, to improve their performance.
Description
Technical field
The present invention relates to a kind of electromagnetic forbidden band structure, in particular to the electromagnet forbidden band structural material on the radio frequency components and parts of being applied in of a kind of small size, broad stopband.
Background technology
Electromagnetic forbidden band structure (Electromagnetic Bandgap (EBG)) or forbidden photon band (PhotonicBandgap (PBG)) material suppress the characteristic of a certain frequency (section) electromagnetic wave propagation because of it is distinctive, have broad application prospects at microwave and optical communication field, caused people's extensive interest in recent years.The difference of root a tree name periodic structure arrangement mode can be divided into three-dimensional, two dimension (also claiming the plane) and one dimension three major types.Wherein the structure of two dimensional surface or directrix plane is maximum because of hanging down characteristics such as section and preparation technology are simple research report in existing document, typical case's representative has " mushroom " structure of people's propositions such as Yablonovitch (referring to Fig. 1, documents 1) and UCPBG (referring to Fig. 2, the documents 2) structural material that proposes of T.Itoh etc.Although above-mentioned two class plane electromagnetic forbidden band structural materials can provide enough forbidden band band widths to satisfy most microwave device application needs, but the plane unit cell size still showed excessive when substrate adopted the lower medium carrier of dielectric constant, like this in order to satisfy limited components and parts physical dimension requirement, the actual unit cell periodicity that uses will reduce greatly in microwave and optical communication components and parts, correspondingly because the minimizing of the unit cell number that adopts, electromagnetic forbidden band structural material suppresses this characteristic performance of electromagnetic wave propagation also will have a greatly reduced quality, and this limitation when the low frequency applications is more outstanding.
