摘要：

A novel compact low-profile printed antenna is designed and analyzed for wireless communication applications. The proposed antenna is composed of a four-steps patch and a three-steps segmental ground plane with two small rectangular slits. To enhance the antenna bandwidth and generate multiple notches, a circular split-ring slot integrated with double strip slots is introduced in the multistep radiating patch, and a inverted-L shaped slot is embedded onto the defected ground plane. The simulated and measured results show that the antenna achieves a wider bandwidth ranging from 3.0 to 16.5 GHz (the return loss <-10 dB) with triple notches of 3.3-3.8 GHz (WiMAX band), 5.1-5.8 GHz (WLAN band), and 7.2-7.8 GHz (X-band). Furthermore, the proposed antenna obtains relative high gain (>4.0 dBi), lower group delay (<2.5 ns) and stable radiation patterns. (C) 2016 Wiley Periodicals, Inc.
