Abstract: An antenna for radio communication apparatus is disclosed which includes a conductive patch having two sinuous slots, a ground, a short circuit connection connecting the patch to the ground, and a feed connection connected to the patch. The antenna has a radiation diagram including a first resonant band including frequencies from 1 950 MHz to 2 100 MHz and having a width greater than 20%. The antenna can operate in a frequency range covering the UMTS, PCS, DCS and possibly GSM bands. The same type of antenna can be used on many kinds of apparatus using different frequency bands, for example frequency bands varying from one country to another. Radio communication apparatus incorporating the above antenna is also disclosed.

Abstract: A electromagnetic wave preventing cover of an mobile phone handset is covered to a casing of a handset and is connected to the antenna seat hole of the handset, so that the transmitting antenna of the mobile phone handset for emitting electromagnetic radiation is far away from the brain, and thus, the harm of the electromagnetic wave to the brain is reduced. A cover has a space for enclosing the mobile phone handset, and has a slot at the front surface of the cover for extending the communicating covering plate of the handset, and the cover has an opening for receiving the handset into the cover. A terminal serves to insert into the antenna seat hole of the mobile phone handset. An antenna is adhered to the outer surface of the communicating covering plate of the handset. A micro-wave shield coaxial cable is fixed within the cover and has an end connected to the terminal and another end connected to the planar antenna.
