摘要： A small volume antenna (100) has the form of a polygonal (e.g., square) board with multiple antenna elements (104, 110) located at vertices (114, 116) (e.g., opposite vertices). The antenna elements (104, 110) include two segments (118, 120, 124, 126) that meet at corners (122, 128) that are located at the vertices (114, 116). Peripheral portions (134, 136, 138, 140) of a ground plane (132) that underlie the segments (118, 120, 124, 126) of the antenna elements are deleted, and slots (154, 162) that have two joined segments (156, 158, 164, 166) that parallel the segments (118, 120, 124, 126) of the antenna elements (104, 110) are formed in the antenna elements. The antenna elements (104, 110) are selectively loaded by switched impedance (e.g., capacitance) networks (172, 176, 178, 180, 182, 186, 190, 192). The antenna (100) is able to support operation in at least two broad operating bands.

摘要： A textured dielectric panel (305, 520, 625, 745, 925, 1035, 1205) is fabricated by applying a first mask pattern (310, 510, 610, 710, 915, 1015, 1210) to a first side of a solid panel made of a first material that is a ceramic dielectric and then sandblasting the solid panel through the first mask pattern from the first side to at least partially generate a shaped cavity (315, 920, 1040). The shaped cavity of the solid panel may be filled with a-second material (330, 740). The first and second materials have substantially differing dielectric constants. The first side and second side of the solid panel may be metallized (325), forming a patch antenna. The shaped cavities can be made more complex by using additional masking and/or sandblasting steps.

摘要： A dual, preferably orthogonally polarized microstrip patch antenna which includes a layer of electrically insulating material in the form of a printed circuit board. First and second sets of electrically conductive patches, preferably of copper, are disposed on one surface of the electrically insulating material, the first set adapted for transmission and/or reception of electromagnetic radiations polarized in a first direction and the second set adapted for transmission and/or reception of electromagnetic radiations polarized in a second direction. Patches of the first set are interlaced with patches of the second set. A feed for each of the patches is coupled to the opposing surface of the electrically insulating material which includes a first plurality of slots, one associated with each of the patches of the first set for polarizing the patches of the first set in the first direction and a second plurality of slots, one associated with each of the patches of the second set for polarizing the patches of the second set in the second direction. The centers of the patches of the first and second sets of patches are disposed in a straight line and the centers of adjacent patches of each of the sets of patches are spaced apart less than one wavelength of the carrier frequency of interest.
