Abstract

The present invention relates to a circularly polarized antenna which is applicable to small-sized communication modules and terminals to have a subminiature and ultralight antenna using a coaxial connector and a serial power distributor, including: an upper printed circuit board having a plurality of horizontal monopole radiation elements which are arranged at a constant interval; a lower printed circuit board having a feed network which is provided at a constant interval from the upper printed circuit board to face the upper printed circuit board; and a plurality of coaxial connectors which electrically connect each horizontal monopole radiation element of the upper printed circuit board with the feed network of the lower printed circuit board.

Description

technical field [0001] The invention relates to a circularly polarized antenna, in particular to a circularly polarized antenna which is miniaturized, ultra-light and has excellent characteristics suitable for small-sized communication modules and terminals. Background technique [0002] Currently, the satellite broadcasting, communication and Internet industries are flourishing as the core media of the information-oriented society of the 21st century. Satellite broadcasting equipment has been developed starting from a satellite dish. [0003] In particular, this development has been prominent in the areas of GPS (Global Positioning System) and DMB (Digital Multimedia Broadcasting). [0004] Also, the devices have become smaller and lighter due to semiconductor and communication technologies, so that the devices can be applied to a wider range of applications not only in automobiles but also in GPS and DMB reception functions in PDAs (Personal Digital Assistants) trend.
