文章出自: https://www.chinatimes.com/realtimenews/20250831003027-260408 The Log Periodic Antenna as known as LPDA is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies. Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas. The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements. With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain. 有成精密Q2毛利率跳升 半導體業務占比已近五成 Horn Antenna 獨家》往墾丁測速桿密集「像考駕照」 商家怨︰生意更難做 868MHz Antenna
