栅缝地同轴馈电金属过孔阶跃阻抗的半槽天线
摘要：
栅缝地同轴馈电金属过孔阶跃阻抗的半槽天线涉及一种缝隙天线，该天线包括介质基板(1)、介质基板(1)上的金属地(2)和辐射槽缝(3)、同轴馈线(4)；金属地(2)上有辐射槽缝(3)和多条平行的栅缝(6)；辐射槽缝(3)的一端短路，另一端开路；在辐射槽缝(3)近开路端部分有两排金属化过孔(7)阵列形成低阻槽缝(8)；辐射槽缝(3)其余部分是高阻槽缝(9)，同轴馈线(4)的外导体(5)与金属地(2)相连，同轴馈线(4)末端内导体(12)跨过高阻槽缝(9)在其边缘(11)，与金属地(2)连接。该天线是多频带工作，可减少天线尺寸、交叉极化、遮挡和改善隔离。
摘要（英）：

The invention relates to a slot antenna and particularly relates to a gate slot ground coaxial feed metal through hole stepped-impedance semi-slot antenna. The semi-slot antenna comprises a medium substrate (1), and a metal ground (2) and a radiation slot (3) which are on the medium substrate (1), and a coaxial feeder (4), wherein the radiation slot (3) and multiple parallel gate slots (6) are on the metal ground (2), one end of the radiation slot (3) is in short circuit, the other end of the radiation slot (3) is in open circuit, the portion of the radiation slot (3) close to the open circuit end is provided with two rows of metalized through holes (7) which form a low-resistance slot (8) in an array mode, the other portion of the radiation slot (3) is a high-resistance slot (9), an outer conductor (5) of the coaxial feeder (4) is connected with the metal ground (2), and an inner conductor (12) at the tail end of the coaxial feeder (4) crosses the high-resistance slot (9) and is connected with the metal ground (2) at an edge (11). The semi-slot antenna realizes multiband operation, can reduce the antenna dimension, cross polarization and shielding and improves isolation.
