Broadband antennas have emerged in the last decade as a possible solution to replace multiple antennas in Radio Frequency (RF) systems that only cover specified frequencies. By using this type of antenna, it is possible to reduce costs, size, and improve performance. Additionally, this type of arrangement opens up possibilities for achieving better transmission rates. Furthermore, these settings could allow for new applications in radar, sensing systems, and meet all requirements. The most common broadband antenna designs include log-periodic antennas, patch antennas, spiral antennas, and complementary antennas. However, there are some challenges with the configurations, with the most well-known being their pattern radiation, interface and manufacturing process. In this work, we have design three model of broadband antenna to cover the frequency range of 1-6 GHz. Combination of Log-periodic and power spiral antenna were simulated in HFSS. In the most of the case the antenna showed a good performance in the desired range.
