Description
Summary:Active integrated antennas receive a great deal of attention because they can reduce the size, weight, cost of the transceiver system and minimizes the connection losses. Due to the mature technology of microwave integrated circuit (MIC) and monolithic microwave integrated circuit (MMIC), the active integrated antennas become an area of growing interest in recent years. Active integrated antennas have many potential applications in wireless communications such as low cost and compact transceivers, detectors and sensors. Various antennas have been integrated into active devices that can be classified into oscillator type, amplifier type and frequency conversion type. In this chapter, the author discusses different type of configuration for active log periodic antenna. The amplifier is incorporated with the antenna at the inset feed, the centre of log periodic antenna and each individual antenna.
