Abstract: It is well known that there is a detrimental effect of the magnetic wave to human brain. It has also been the constant effort to minimize the size of cellular phone for easy handling and operation. From the stand point of design, we first time propose to integrate the antenna and the microphone into a single part and to place this single part at the bottom of the phone body. When the cell phone is in use, the antenna (with microphone enclosed in antenna cap at the tip) is pulled out from the bottom of the phone body, this is directly opposite to the common way of putting antenna on top of the phone, hence to alleviate the magnetic effect to the brain and at the same time to minimize the phone size.

IPC: H04B1/707
Filed: 2000-08-04
Abstract: A transmitter for wireless communications provides multiple types of orthogonality to improve transmit diversity. Transmit diversity is improved by using both coding and carrier frequency orthogonality. Data to be transmitted is broken into four parallel channels. Two of the channels are transmitted on a first carrier signal and the other two channels are transmitted on a second carrier signal. Channels transmitted on the same carrier signal are provided with orthogonal codes so that they may be separated by a receiver. Channels transmitted on different carrier signals may be encoded with identical orthogonal codes. The modulated carrier signals are then transmitted using at least two antennas, where one antenna is used for each carrier.
