LTE/5G C-band MIMO antennas for laptop computers

The paper presents a design of MIMO antennas for laptop computers operating at LTE (long term evolution) band and 5th generation wireless systems (5G) C-band. The antenna is designed with a parasitic open slot and a PIFA located at the top edge of the display ground. The antenna can cover the LTE 700 (698-787 MHz), LTE 2300 (2305-2400 MHz), LTE 2500 (2500-2690 MHz) and 5G C-band (3400-3600 MHz). The antenna size is 12 × 75 × 4 mm
