Numerical comparison between 2 antennas—with and without GPLA substrate. (A) Normalized absorbed power within the device (in %)—green line—with GPLA, purple—without GPLA. (B), (C) and (E) Radiation patterns at 850 MHz, 1.5 GHz and 7 GHz, respectively. (D) Antenna layout. (F), (G) and (H) Color maps of unwrapped radiation patterns (linear scale). Horizontal and vertical axes—angular and frequency dependences, respectively. Antenna gain is represented by color in linear scale.
