Abstract

The invention discloses a preparation method for a micro-strip ceramic antenna. The preparation method for the micro-strip ceramic antenna includes steps that 1) adding ceramic powder into mixed liquid of water and glycol; 2) adding ammonium polyacrylate; 3) adding the mixture of acrylic amide and N,N'-methylene bisacrylamide; 4) adding ammonium persulphate and tetramethylethylenediamine, pouring into a mould, preserving heat for 30 minutes to 2 hours at 65 to 90 degrees centigrade, and demoulding to obtain a ceramic blank; 5) dumping and sintering the ceramic blank body to obtain a piece of ceramic tile; 6) using silver slurry to metalize the upper and lower surfaces of the ceramic tile, and inserting a silver needle in a feed hole to obtain the micro-strip ceramic antenna. The micro-strip ceramic antenna is formed under normal pressure and does not need powder compression, the needle is made of ordinary metal, plastic or glass, and the micro-strip ceramic antenna is capable of being formed even the aperture is less than 0.5 millimeters; the mould material and design cost are reduced, and meanwhile, the cured blank body is high in intensity and easy to demould.

Description

technical field [0001] The invention belongs to the technical field of microstrip patch antennas, and in particular relates to a preparation method of a microstrip ceramic antenna. Background technique [0002] Microstrip antenna is a new type of antenna developed in the past 30 years. It is characterized by small size, light weight, thin planar structure, conformal to the aircraft, easy to integrate with printed circuit boards, simple manufacturing process, low cost, easy to achieve linear polarization or circular polarization, and can obtain unidirectional Wide-directional maps have been widely used in a wide range of 100MHz~100GHz, including GPS, Beidou navigation, satellite communications, radar, missiles, environmental monitoring, biomedicine, portable radio equipment, etc. [0003] The preparation process of the microstrip antenna for navigation in the prior art is to use a binder (such as PVA, PVB) to granulate the microwave dielectric ceramic powder, and dry press ...
