Abstract
A present invention relates to a monopole wideband antenna, that is a wall mounted handing type antenna capable of providing easy frequency adjustment and operating at broad frequency band range. Moreover, the monopole wideband antenna of the invention can be applied in various electronic devices, and is advantageous in its low cost and small size since it can be fabricated directly using a means of print formation upon a circuitboard.
Claims10
A monopole wideband antenna, adapted to be formed on a printed circuitboard, comprising:
- an antenna unit, composed of a radiation element and a frequency adjustment element that are independently disposed with respect to each other, while allowing the radiation element to be further configured with a first extension element, a second extension element and a signal feed point in a manner that the first extension element is formed extending in a first direction into a first impedance matching adjustment area;
- the second extension element is connected to the first extension element by one end thereof and is extending in a second direction into a primary radiation area, and the signal feed point is connected to the joint of the first and the second extension elements and is extending in a third direction, and the frequency adjustment element is arranged at a position sandwiched between the first and the second extension elements;
- a ground unit, disposed neighboring to the signal feed point;
- and
- a second impedance matching adjustment area, being an area sandwiched between the ground unit and the antenna unit.
