Embodiment 1
[0122] Sample 1 to Sample 2 are used in 5G system. LCP 1 was formed from 60% HBA, 4% HNA, 18% TA and 18% BP. LCP2 is formed from 48% HNA, 2% HBA, 25% BP and 25% TA. Compounding was performed using an 18 mm single screw extruder. Samples were injection molded into panels (60mm x 60mm). The formulation is described below.
[0124] The thermal and mechanical properties of samples 1 to 2 were tested. The result is shown below.

Embodiment 2
[0128] Samples 3 to 5 were extruded into films for 5G systems. Sample 3 contained 100 wt.% LCP 3 formed from 73% HBA and 27% HNA. Sample 4 contained 100 wt.% LCP 4 formed from 79.3% HBA, 20% HNA and 0.7% TA. Sample 5 contained 75 wt.% LCP 3 and 25 wt.% PTFE. The thermal and mechanical properties of samples 3 to 5 were tested. The result is shown below.
[0131] Samples 6 to 8 were extruded into films for use in printed circuit boards. Sample 6 contained 80 wt.% LCP 5 and 20 wt.% PTFE, sample 7 contained 75 wt.% LCP 5 and 25 wt.% PTFE 1, and sample 8 contained 75 wt.% LCP 4 and 25 wt.% PTFE. LCP 5 was formed from 43% HBA, 9% TA, 29% Hq and 20% NDA. In addition, the D50 particle size of PTFE 1 is 4 μm, and the D90 particle size is 15 μm.
[0132] The thermal and mechanical properties of samples 6 to 8 were tested. The result is shown below.

Abstract
There is provided a 5G system including at least one antenna element configured to transmit and receive a 5G radio frequency signal and at least one electronic component. The antenna element, the electronic component, or both, includes a polymer composition including a liquid crystal polymer containing repeating units derived from a naphthenic hydroxycarboxylic acid and / or a naphthenic dicarboxylic acid in an amount of about 10 mol.% or more. Further, the polymer composition exhibits a dielectric constant of about 5 or less and a dissipation factor of about 0.05 or less at a frequency of 10 GHz.
