단락된 전자기 결합 스터브를 활용한 광대역 차량용 C-PAD 안테나 설계

초록

In this study, an automotive two-port MIMO C-PAD antenna with 1 Tx and 2 Rx for 4G/5G IVI wireless communication systems was designed. The C-PAD antenna consisted of two antenna elements using a microstrip line monopole on a two-layer PCB. To implement the wideband characteristics of 1,710 to 3,500 MHz, two antenna elements were designed using a basic monopole structure and a shorted coupling stub. The fabricated C-PAD antenna had a VSWR below 2.1 in the 1,710 to 3,500 MHz range and a measured gain of −2.14 to 1.52 dBi at θ=60°, thus exhibiting an excellent performance.
