摘要
The present invention relates to a microstrip sector antenna (1) comprising a metal microstrip structure (3) formed by interconnected radiating elements (4), underneath of which a first dielectric layer (7) and a metal grounded layer (2) are disposed. In order to increase the Half Power Beam Width (HPBW) of such antenna, in particular antenna having the microstrip structure designed for 90-degree antenna, over the microstrip structure (3) in a distance (D) of between 0.04 to 0.4 of the antenna wavelength (λo) a second dielectric layer (10) is disposed. Said dielectric layer (10) preferably comprises at least one dielectric substrate (11), preferably laminate made on the basis of epoxy glass, and preferably is a part of a housing of the antenna (1).
