Embodiment 1

[0024] 4 parts of ferrocene phthalocyanine copper organic magnet and 3 parts of nanometer (60-80nm) calcium titanate porcelain (CaTiO 3 ) The powder is soaked in 50ml of acrylic acid (component D)-ethanol solution containing 0.2% at 50-60°C for 2 hours, then filtered, then washed and dried with acetone, and fully mixed with a high-speed stirrer (12000prm / min). Afterwards, mix with 3 parts of polystyrene in an open mill at 130-150°C for 30-40 minutes, the electromagnetic parameter product (μ'ε') of the obtained composite electromagnetic dielectric substrate = 39, and the dielectric loss tangent tgδ ≤2×10 -3 , use it to make a 30×30×1.5mm copper-clad substrate, and make a 450MHz urban light control microstrip antenna with a bandwidth of 18%.

Abstract

The invention discloses a composite electromagnetic medium material containing a dicyclopentadienyl iron phthalocyanine metal organic magnetic body and a corresponding preparation method. The material consists of the dicyclopentadienyl iron phthalocyanine metal organic magnetic body (A) containing Cu, Co or Ni, a nano ceramic powder material (B), a thermoplastic resin material (C) and a modifier (D). The material has the remarkable characteristics that the material has higher electromagnetic parameter product (mu'epsilon'=30-100) and lower dielectric loss (tg delta is less than 2*10 -3 ) at the extensive frequency band of 0.1 to 45GHz; when the material is used for manufacturing a micro-strip antenna or an electronic device, the bandwidth of the material can reach over 15 to 40 percent so as to greatly reduce the geometric dimension of the electronic device or the antenna and keep good gain; and the material has simple process and low price and is easy to realize industrialization.

Description

technical field [0001] The invention relates to a composite electromagnetic dielectric base material which can be used for making microwave devices and microstrip antennas, in particular to an organometallic magnet composite electromagnetic dielectric material and its related preparation method. Background technique [0002] Both modern warfare and the development of the national economy require electronic equipment such as communications, radar, navigation, and electronic countermeasures to be multifunctional, miniaturized, and highly maneuverable. In order to meet this need, electronic technology is developing towards lightweight, miniaturization and planarization, that is, light, small and thin. Broadband and ultra-wideband applications, especially when applied to low frequency bands, the broadband and miniaturization of microwave components and antennas have always been the main problems that plague radio engineers and technicians. In order to make microwave devices lig...
