Custom L1 L2 GPS Antenna 1575.42MHz 1227MHz Ceramic Double Layer Patch Bulit In Antenna
Background technology:
In recent years, with the development of satellite communication technology, the rapid growth of satellite communication business and satellite mobile communication, the lower frequency band of microwave in the past has become crowded. Therefore, Ku band or even Ka band communication is used in satellite communication to meet the demand of large amount of information. In some special application fields, such as mobile communication and navigation communication, the antenna is required to have the characteristics of good concealment and strong mobility. However, the traditional antenna is no longer suitable for the needs of modern satellite communication system because of its large size, poor mobility, difficult to be conformal with the carrier and easy to expose the target. The modern satellite communication system puts forward higher requirements for the antenna, which not only requires miniaturization, light weight, good concealment and mobility, but also requires dual polarization, multi frequency and bandwidth characteristics in order to meet the needs of large capacity communication. The characteristics of the antenna are closely related to the dielectric substrate, so choosing the appropriate dielectric substrate is the key to design the antenna Find the basis of the antenna.
In order to effectively increase the Q value of microstrip antenna and broaden the working frequency band, it is necessary to choose the dielectric substrate with lower dielectric constant and thicker thickness as far as possible; for the feed network, choosing the thinner substrate will effectively reduce the pseudo radiation from the feeder, enhance the binding effect of the dielectric on the wave and increase the energy coupling efficiency. Therefore, when selecting the dielectric substrate, according to the specific application, it is necessary to first consider the multiple parameters of the substrate, such as dielectric constant, dielectric thickness, loss tangent, etc., and then consider the multiple properties of the dielectric substrate, such as the uniformity of the substrate thickness, the stability of the substrate with the change of humidity and temperature, the chemical resistance, tensile strength and structural strength, flexibility, impact resistance and workability of the substrate Adhesion, etc.
Therefore, it is necessary to develop a new ceramic substrate and antenna to meet the needs of modern communication technology.
