Frequency Reconfigurable Microstrip Loop Antenna Covering LTE Bands With MIMO Implementation and Wideband Microstrip Slot Antenna all for Portable Wireless DTV Media Player

摘要

A microstrip slot antenna covering Digital TV (DTV) and frequency reconfigurable microstrip printed loop antenna operating at LTE bands 3 (1.8 GHz) and 7 (2.6 GHz) with multiple-input-multiple-output (MIMO) implementation are designed which can find applications in portable wireless DTV media players. The DTV antenna is matched from 496–862 MHz and LTE bands 3 and 7 from 1710–1880 MHz and 2500–2700 MHz, respectively, all considering ${rm S}_{11} = -6~{rm dB}$ matching criterion. Further, the LTE bands antennas are frequency reconfigurable antennas and its MIMO implementation shows an envelope correlation (EC) below 0.22 for both the LTE bands. Prototype antennas were fabricated and experimental verification was performed.
