PURPOSE: Provided is a patch antenna that is suited for surface packaging on a printed circuit board and has a short-circuiting conductor. CONSTITUTION: The patch antenna comprises two layers which in the assembled state each form a lower, first and an upper, second patch pattern resonator(10,20), respectively. The first resonator(10) comprises a first substrate(11). The upper surface of the first substrate(11) supports a first pattern of metal patches(13) which extends over a major portion of the upper surface, while only edge portions(111) of this upper surface remain free. A first portion(14) of a short-circuit conductor extends between the ground metallization(12) and the first pattern of patches(13). The second resonator(20) of patterned patches is formed by a second substrate(21) on whose upper surface a second pattern of metal patches(23) is provided which extends over the entire upper surface. Furthermore, a second portion(24) of the short-circuit conductor is present in the second substrate(21). When the antenna is assembled through joining together of the two resonators in the direction of the arrow(A), the second portion(24) will form a continuation of the first portion(14), whereby the short-circuit conductor is created. |
