The design of antennas for mobile devices is becoming increasingly challenging. New wireless standards, touting enhanced throughput, require both the coverage of more frequency bands per antenna (to support LTE-A inter-band carrier aggregation for example), as well as more antennas per mobile device (to support IEEE802.11ac or LTE-A MIMO for example). At the same time, mobile devices become sleeker. The Chu-Harrington limit, however, bounds and relates the bandwidth, the efficiency and the volume of electrically small antennas. ChipDesign has therefore developed a multi-functional tunable antenna, which allows multi-band 2G/3G/4G cellular communication, 866 MHz RFID tag reading, L-band DVB-H and S-band SDARS broadcast reception, L2 GPS navigation and 2.45 GHz WLAN (IEEE802.11a/b/g/n/ac) and WPAN (Bluetooth and ZigBee) connectivity. ChipDesign believes that its on-demand-reconfigurable multi-functional antenna paradigm can provide a solution to the MIMO-on-the-handset conundrum.
