Abstract:
PROBLEM TO BE SOLVED: To provide a radio-frequency (RF) integrated circuit (IC) package having a characteristic suitable for mass production. SOLUTION: The radio-frequency integrated circuit chip package 100 having N-integrated aperture coupled patch antennas 104 (N is at least one) includes a cover part and a main part coupled to the cover part. The main part are arranged at intervals from the patch antenna 104 to the inside, and include the ground surface 110 parallel to it. The ground surface is formed so as to internally have the coupled apertural area slot 113. The slot 113 substantially faces the patch antenna 104. The main parts are also arranged at intervals from the patch antenna 104 to the inside, and include the feed line 114 in parallel to it and the radio-frequency chip 162 coupled to the feed line 114 and the ground surface 110. The cover part and the main part cooperatively set an antenna cavity 150, and the patch antenna 104 is arranged in the antenna cavity 150. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
A radio-frequency integrated circuit chip package has N integrated aperture-coupled patch antennas, N being at least two, and includes N generally planar patches, and at least one generally planar ground plane. The ground plane is formed with at least N coupling aperture slots therein. N feed lines are spaced inwardly from the ground plane and substantially parallel thereto, and at least one radio-frequency chip is spaced inwardly from the feed lines and coupled to the feed lines and the ground plane. A first substrate layer is formed with the chip located in a chip-receiving cavity. A second substrate layer is interposed be-tween the ground plane and a plane defined by the patch. The patch is formed in a first metal layer, the ground plane in a second metal layer, and the second substrate layer defines an antenna cavity in which the N generally planar patches are located.
