摘要： An arrangement for increasing the level of radiated and received energy in a telescoping antenna while the antenna is in a collapsed position. The increase in energy is obtained through use of a sliding member which projects from the base of the antenna and contacts antenna matching circuitry for making changes to this circuitry when the antenna is collapsed. Initially tuned for resonating signals for transmission and reception with the antenna in an extended position, the antenna matching circuitry is retuned by a switching action provided by the sliding member for more effective resonating of these signals with the shorter length antenna. The switching action of the sliding member also activates gain control circuitry which increases the signal levels in both an associated transmitter and receiver when the antenna is in the collapsed position.

摘要： A telescoping antenna structure suitable for use in a portable transceiver for increasing the level of radiated or received r-f energy while in a collapsed position and also obtaining the maximum permitted level of radiated r-f energy while in an extended position. The increase in r-f energy in the antenna while in the collapsed position is obtained through use of a projectable sliding member affixed to the antenna which comes in contact with and makes electrical changes to antenna tuning circuitry when the antenna is adjusted from the extended position to the collapsed position.

摘要： A bimodal portable telephone provides cellular service and improved cordless service in a common handset. Operation of the bimodal portable telephone in a cellular telephone system provides telephone service over a wide geographical area of coverage through operation with multiple cellular bases and in a cordless telephone system provides telephone service over a localized geographical area of coverage through operation with an associated cordless base. The cordless service provides improved performance over convention cordless telephone service by advantageously employing a frequency hopping spread spectrum modulation technique for communications between the portable telephone and the cordless base unit. This improved performance achieves increased operating range of the cordless telephone system. This increased operating range is particular advantageous to the user of the portable telephone in that it permits this more economical system to be used over a much greater distance than is possible with convention cordless telephone service. Also commonality of circuitry within the portable telephone is facilitied through the selection of operating frequencies for the cordless telephone system to be in close proximity with those of the cellular telephone system.
摘要翻译： 双模便携式电话在普通手机中提供蜂窝服务和改进的无绳服务。 双蜂窝便携式电话在蜂窝电话系统中的操作通过多个蜂窝基站的操作在广泛的覆盖范围的地理区域上提供电话服务，并且在无绳电话系统中通过操作与相关的无绳基站在覆盖范围内提供电话服务 。 无线服务通过有利地采用跳频扩频调制技术来提供便携式电话和无绳基站单元之间的通信，从而提供了比常规无绳电话业务更好的性能。 这种改进的性能实现了无绳电话系统的增加的操作范围。 这种增加的操作范围对于便携式电话的用户是特别有利的，因为它允许在比常规无绳电话服务可能的更大的距离上使用这种更经济的系统。 通过选择无绳电话系统的操作频率与蜂窝电话系统的操作频率非常接近，便携式电话中的电路的通用性也是有利的。
