Patent ID: 8774068

Claim:
An antenna switch structure for use in a mobile communication terminal, the antenna switch structure comprising: a first transceiver comprising a low band main circuit path configured to process signals of a low main frequency band; a first receiver comprising a low band diversity circuit path configured to process signals of a low diversity frequency band; a second transceiver comprising a high band main circuit path configured to process signals of a high main frequency band; a second receiver comprising a high band diversity circuit path configured to process signals of a high diversity frequency band; a first dual band antenna configured to transmit and receive wireless signals of two or more frequency bands; a second dual band antenna configured to transmit and receive wireless signals of two or more frequency bands; a first diplexer connected to the first dual band antenna comprising a first port and a second port; a second diplexer connected to the second dual band antenna comprising a first port and a second port; a first switch controlled to switch between a first mode that connects the first port of the of the first diplexer to the first transceiver and the first port of the second diplexer to the first receiver and a second mode that connects the first port of the first diplexer to the first receiver and the first port of the second diplexer to the first transceiver, wherein a mode of the first switch is selected in response to signals received at the first switch; and a second switch controlled to switch between a first mode that connects the second port of the first diplexer to the second transceiver and the second port of the second diplexer to the second receiver and a second mode that connects the second port of the first diplexer to the second receiver and the second port of the second diplexer to the second transceiver, wherein a mode of the second switch is selected in response to signals received at the second switch.
