A Metal Rim Integrated Open Slot Antenna with a Band-Stop Matching Circuit for LTE/WWAN Smartphones

摘要

A metal rim integrated open slot antenna with a band-stop matching circuit for LTE/WWAN smartphones is presented in this letter. The proposed antenna comprises two branch slots which share a same opening disposed at the top edge of the ground board, the longer open slot structure is excited by a 50-Ω microstrip line with a band-stop matching circuit. By adjusting the length of the slot, position of the microstrip line, values of the capacitor and the inductor, the antenna can cover the LTE/WWAN operations in the 698-960 MHz and 1710-2690 MHz bands. Simulated and measured results of the antenna are presented and discussed.
