DETAILED DESCRIPTION

[0007] Electronic devices have an enclosure or housing in which electronic components, such as a processor, a memory, a power source, a cooling fan, an I/O port, an antenna, etc., are present. The enclosure of an electronic device also houses a radio transceiver circuitry which may include multiple signal processors for processing various communication signals over different radio frequency channels. One or more signai processors may be coupled to an in-built antenna for transceiving the signals. The signal processors can generate communication signals for transmission and can also process and decode received communication signals. The signal processors may be main signal processors which are capable of both generating signals for transmission and decoding received signals; or auxiliary signal processors which are capable of decoding received signals.

[0008] In the radio transceiver circuitry, generally, an Input/Output (I/O) port of a tow band Wireless Wide Area Network (WWAN) main signal processor, an I/O port of a mid band WWAN main signal processor, and an I/O port of a high hand WWAN main signal processor are multiplexed together to a single port to which a first antenna is connected. This muittptexing is usually done by using two diplexers. The first antenna transceives WWAN signals over the tow-band, mid- band, and high-band. Further, an I/O port of a WWAN auxiliary signal processor and an I/O port of a Global Positioning System (GPS) signai processor are multiplexed together to a single port to which a second antenna is connected. The I/O port of the WWAN auxiliary signal processor and the I/O port of the GPS signal processor is multiplexed using another dipiexer. The second antenna receives WWAN signals and GPS signals.

[00093 The diplexers in the radio transceiver circuitry increases insertion ioss and thereby reduces signai strength and affects signai quality. Also, the electronic devices having the radio transceiver circuitry are generally compact In nature. The diplexers in the radio transceiver circuitry may utilize more space thereby adversely affecting the compactness of the electronic devices.

[0010] The present subject matter reiates to configuration and arrangement of antennas in an electronic device. According to the present subject matter, a separate antenna is coupled to a high band Wireless Wide Area Network (WWAN) main signal processor; and a single antenna is coupied to a Global Positioning System (GPS) signal processor and a Wireless Local Area Network (WLAN) signal processor. [0011] In an example implementation, a first antenna is coupied to the high band WWAN main signal processor, The first antenna is to transceive high band WWAN signals. A second antenna is coupled to the GPS signal processor and a WLAN ssgnai processor. The second antenna is to transceive GPS signals and WLAN signals

{00123 Thus, with the proposed subject matter, high band WWAN signals are transceived through a separate antenna, which is not otherwise the case in a RF transceiver circuitry. Hence, the i/O port of the high band WWAN main signal processor is not multiplexed with the I/O ports of the mid-band and Sow-band WWAN main signal processors, thereby reducing the number of dipSexers in the radio transceiver circuitry by one. Due to elimination of the dipiexer from the radio transceiver circuitry, insertion loss may be reduced, thereby improving signal strength,

[0013] Further, in the proposed subject matter, a single antenna is coupied to the GPS signal processor and the WLAN signal processor. To this end, the i/O port of the GPS signal processor is multiplexed with the I/O port of the WLAN signal processor, instead of being multiplexed with the I/O port of the WWAN auxiliary signal processor as in other systems. The insertion loss at a dipiexer multiplexing the I/O port of the GPS signal processor with the I/O port of the WLAN signal processor is less as compared to the insertion loss at the dipiexer multiplexing the I/O port of the GPS signai processor with the I/O port of the WWAN auxiliary signal processor. This is because, when GPS signals and WWAN signals pass through a dipiexer, greater power is consumed by the dipiexer to multiplex/demultiplex the GPS and WWAN signals, since the difference in operating frequencies of the GPS and WWAN signals is smalf, i.e., in the order of 100-200 Mega Hertz (MHz). Whereas, when GPS signals and WLAN signals pass through a dipiexer, lesser power is consumed by the dipiexer to multiplex/demultiplex the GPS and WLAN signals as the difference in operating frequencies of the GPS and WLAN signals is comparatively larger, i.e., in the order of 900 MHz to 1 Giga Hertz (GHz). Hence, with the antenna configuration of the present subject matter insertion loss is further reduced which provides improved signai strength and better signal quality. [0014] The following detailed description refers to fie accompanying drawings. Wherever posslbie, the same reference numbers are used in the drawings and the following description to refer to the same or similar parts. While several examples are described in the description, modifications, adaptations, and other implementations are possible. Accordingly, the following detailed description does not limit the disclosed examples, Instead, the proper scope of the disclosed examples may be defined by the appended claims.
