BROADBAND ANTENNA SYSTEMS AND METHODS |
摘要 |
A multi-band antenna that may be designed to operate well in both Public Safety (PS) and Long-Term Evolution (LTE) wireless communication may employ a stepped T-shape structure in conjunction with patch tapering or a reconfigurable ground plane architecture and capacitive feeding to achieve broad bandwidth performance (e.g., over a frequency range from 220 MHz to 4900 MHz). To achieve desired performance, the antenna may include a three-dimensional structure having lateral dimensions of approximately 0.25lambda in length and 0.01lambda in height at a low desired frequency of operation (e.g., 426 MHz). In some embodiments, the disclosed antenna may exhibit good gain flatness and have a radiation pattern that remains substantially constant over a broad range of operating frequencies. |
