Abstract: An antenna array may be provided. The antenna array comprises N radiating elements and M phase shifters, where M is less than N. N may be an integer greater than or equal to three. M may be an integer greater than or equal to two. The N radiating elements may be arranged linearly. Two adjacent radiating elements may be separated substantially by an integer multiple of a first spacing. The N radiating elements may be grouped into a first number of groups, wherein each of the groups comprises at least one and at most M adjacent radiating elements. The N radiating elements may be connected to the M phase shifters in such a way that: one radiating element is connected to at most one phase shifter; and two sequential radiating elements connected to the same phase shifter are separated by a second spacing, the second spacing being substantially an integer multiple of M multiplied by the first spacing.

Abstract: A brake device for a fishing reel has a first brake disk, a second brake disk and two abutting discs. The first brake disk has an outer side, a through hole and a friction face. The friction face is formed on the outer side of the first brake disk and is adapted to face a minor panel of a clutch of the fishing reel. The second brake disk parallels the first brake disk and has two sides, a through hole and two friction faces. The friction faces are respectively formed on the sides of the second brake disk and are adapted to face the minor panel and a major panel of the clutch. The abutting discs are mounted in the through hole of the second brake disk to respectively abut the panels of the clutch to enable the second brake disk to be mounted between the panels at intervals.

Abstract: The fishing reel has a body and a deceleration controller. The body has a magnetic spool and a side cover. The deceleration controller is mounted on the side cover and has a mounting tube, a moving shaft, a magnetic assembly and a switching button. The mounting tube is mounted through the side cover and has an inner thread. The moving shaft is movably mounted through the mounting tube and has an inside end, an outside end, an outer surface and a thread section. The thread section is formed in the outer surface of the moving shaft and screwed with the inner thread of the mounting tube. The magnetic assembly is securely mounted on the inside end of the moving shaft. The switching button is mounted securely on the outside end of the moving shaft to turn the moving shaft moveable inwardly or outwardly relative to the magnetic spool.

Abstract: A fishing reel has a body, a spool, a handle and a warning device. The body has a spool axle rotatably mounted in the body. The spool is rotatably and coaxially mounted around the spool axle of the body. The handle is rotatably mounted on the body and is connected to the spool. The warning device is mounted between the spool and the spool axle and has at least one illuminating element, an annular coil and an annular permanent magnet. Each illuminating element is mounted through the spool. The annular coil is coaxially mounted in the spool and is electrically connected to each illuminating element. The annular permanent magnet is coaxially mounted around the spool axle, corresponds to the coil and is separated from the coil by a gap.

Abstract: A spool has a cylindrical body, a central hole and two recesses. The central hole is defined through the cylindrical body to define two openings respectively at two ends of the cylindrical body. The line recesses are defined in the outer surface of the cylindrical body for two different fishing lines to respectively wound around. Accordingly, the spool is able to simultaneously receive two kinds of fishing lines to improve convenience in use.
