Abstract

In this paper, a novel technique of collocating millimeter-wave end-fire 5G beam steerable array antenna with a low-frequency PIFA is presented. In this technique, the low-frequency antenna can be transparent by using some grating strips between the low- and high-frequency antennas. A quad-element mm-wave array with end-fire radiation patterns operating in 22-31 GHz is integrated with a dual-band low-frequency PIFA in a mobile terminal. The novelty of this paper is the collocation of high-frequency end-fire 5G antenna array with an old generation low-frequency antenna such as 4G in small space in the mobile terminal without interfering with the radiation pattern and impedance matching of both low- and high-frequency antennas. The proposed 5G antenna covers 22-31 GHz and can scan ± 50 degree with the scan loss of better than 3 dB. The coverage efficiency of the proposed mm-wave 5G antenna is better than 50 and 80 % for a minimum gain of 4 and 0 dBi in 22-31 GHz, respectively. The gain of the high-frequency antenna array is better than 9.5 dBi at 28 GHz. The low-frequency antenna covers some practical 4G LTE bands from 740-960 MHz and 1.7-2.2 GHz bands. The measured results in both low- and high-frequency agree well with the simulations.
