“…A larger volume of metal increases the size of the RF-ground, which restricts the antenna size and placement possibilities even more. To ensure good antenna performance, phone manufactures have cut slots into the back cover, as is seen in many commercial products, or proposed in, e.g., [11][12][13][14][15][16][17]. Slotless covers have been presented in [18,19], but they have large openings in the side rim for the antennas.…”

Abstract-Current phones include more metal than earlier, which deteriorates the performance of antennas. This paper presents the first complete antenna set designed for a modern handset with a full metal back cover. 4G, Wi-Fi, and GPS antennas are integrated into the metallic side frame of the device in a realistic model. The designed antennas are either capacitive coupling elements with reactive loads or slot antennas. Fixed matching circuits are used to improve total efficiency. The passive implementation enables the use of carrier aggregation (CA) to increase the data rates, and includes also the multipleinput multiple-output (MIMO) operation for 4G and Wi-Fi. The designed antennas cover frequency bands 704-960 MHz, 1.56-1.61 GHz, 1.71-2.69 GHz, 2.4-2.484 GHz, and 5.15-5.875 GHz, producing in measurements a good agreement with simulation results.
