A panel antenna includes a panel portion and a feeder cable. The panel portion includes a first portion and a second portion connected with the first portion to form a L-shape. A first metal sheet is disposed on the first portion. A second metal sheet is disposed on the second portion. The first and second metal sheets connect with each other. The first metal sheet has a feeding point and the second metal sheet has an elongate connecting arm. The overall structure of the first and second metal sheets forms a L-shape The feeder cable includes an inner conductor electrically connecting with the feeding point and an outer conductor extending along the connecting arm. The outer conductor has an exposed part contacted with the connecting arm.

Panel antenna

A dipole antenna assembly () includes a dipole antenna () and a feeding element () connecting with the dipole antenna. The dipole antenna includes a radiation portion (), a ground portion () and a circuit (). The feeding element includes a central conductor () soldered on the radiation portion at a first position, and a shielding layer () soldered on the ground portion at a second position. The circuit includes one end connecting with the radiation portion at the first position, and another end connecting with the ground position at the second position for impedance matching.

Dipole antenna assembly

A dual-band dipole antenna () includes a ground radiating portion (), a signal radiating portion () and a feed wire (). The feed wire () has a ground portion () connected to the ground radiating portion (), and a core conduct () connected to the signal radiating portion (). The signal radiating portion () has a first branch (), a second branch () having a same length and a same width as the first branch (), and a middle portion () connecting the first branch () and the second branch () at connecting points. Each of the first branch () and the second branch () has a first radiating length (D) extending from the connecting point and a second radiating length (D) extending from the connecting point.

Dual-band dipole antenna

An antenna () comprising a first pole portion (), a first helical portion (), a second pole portion () and a second helical portion (), each of which connects the next in turn along a line, said second helical portion () having a plurality of cylindrical whorls, wherein the second helical portion is coated with metal () so that the whorls are connected to a neighbor one by the metal ().
