Abstract
A structure and method for minimizing adverse effects on the performance characteristics of an antenna in a wireless communications device caused by user interference. An electrically symmetrical microstrip antenna (208) is positioned internal to the body of the wireless device (202). When the device is closed (in a passive state) the antenna (208) is connected to the transceiver at one of the electrically symmetrical ends (210). When the device (202) is opened and more likely to be subject to user interference due to proximity of the hand or body to the device, the antenna (208) is connected to the transceiver at the other electrically symmetrical end (212). Shifting the connection point of the antenna (208) allows the antenna to be relocated to a position that is less likely to be subject to adverse effects caused by body proximity. In another embodiment, two microstrip antennas (302) and (308) are positioned at opposite ends, and internal to, the casing of the wireless device (202). An antenna switch (306) is used to control which antenna is connected to the transceiver unit at any given time. When the device (202) is closed, the switch can connect the antenna with the better signal (usually the antenna closest to the transceiver (308) to the transceiver (218). When the device is opened, the switch can connect the antenna least affected by user interference (302) to the transceiver unit (218).
Description
Invention field
The present invention relates to antenna, more particularly, relate to the antenna setting in cell phone.
Background of invention
Antenna generally is used to transmit and receive electromagnetic wave.Antenna comes work by current conversion being become (transmission) electromagnetic wave and converting electric current to from (reception) electromagnetic wave.It is " gain " that of antenna performance measures.Gain is based on the directivity and the efficient of antenna.Directivity is day ability of bundle of lines energy accumulating on required direction.If desired, can be in narrow beam width energy accumulating.The energy of this focusing provides the ability of striding telecommunication, but along with the angle of antenna changes, the direction of wave beam also changes, and therefore for good signal, needs the suitable orientation of antenna.The efficient of antenna relates to the losing quantity relevant with the reception of signal specific.Surely can be with its intended purpose by many different modes designing antennas.For example, in cellular communication, antenna is designed to obtain maximum " gain " on characteristic frequency.Such design generally is to realize by the antenna of part that structure equals the wavelength of required operating frequency.
Be used in antenna in the travelling carriage of cellular communication generally on electric and all less on the mechanical structure.The size of antenna general common with on the body that is worn over the user or the communicator in hand held become.The inside antenna of travelling carriage provides to be convenient to handle assembly and to fill in favourable shape factor in pocket or the suitcase.Exterior antenna has increased the length of travelling carriage, and is often stumbled when device is removed or puts back to pocket or suitcase.But when using inside antenna, various factors may hinder and receive and emission.Special a kind of obstruction of being concerned about is the interference of user of mobile station health in cellular communication.This interference normally occurs between travelling carriage and the base station owing to user's head or hand are in.
User's health produces the interference of a kind of being called " health effect ".Produce the health effect and be because people's health has conducted away electromagnetic wave from the transceiver of travelling carriage.Under cellular situation, because the user is close to mobile portable antennas, so this effect is stronger.For example, usually can see that user of mobile station hand when using phone covers the part of antenna.
When the user held to travelling carriage, in fact hand became the part of the ground plate of antenna.The variation of consequent ground plate size may have negative effect to the performance characteristics of antenna.May comprise for example frequency response skew and lower efficiency (comprising the obvious loss of signal) the influence of antenna.
