Document Type and Number:
Japanese Patent JP3435378
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an array antenna having a directivity pattern suitable for radar together with impedance matching characteristics over a wide band capable of sufficiently guaranteeing performance against frequency characteristic fluctuation caused by a sever use environment (such as temperature change, for example), to become a problem in the case of loading on an airplane or the like.
SOLUTION: This array antenna is composed of a power feeding element provided with a power feeding means, a first power non-feeding element arranged in front of the power feeding element within a wavelength of 0.1, and a second power non-feeding element arranged at the back of the power feeding element at an interval exceeding a wavelength of 0.1 at least.
