A novel planar LTE antenna with dual notched bands is proposed and investigated. The need of band rejection related to commercial issues. In certain areas, the usage of bands are restricted and decided by FCC and ITU. So the users should not get frequency bands which are restricted in a particular area provided by network operator. This design consists of a square patch and a modified grounded plane. To realize dual notched bands characteristics, a T-shaped stub embedded in the square slot of the radiation patch and a pair of U-shaped parasitic strips beside the feed line is used. The advantage of this antenna is the high rejection level in the stop band. The measured results show that the proposed dual-notched-bands planar antenna shows a very wide bandwidth from 1.8 to 11.0 GHz defined by voltage standing wave ratio , with two notched bands of 3.3-4.0 GHz (WiMAX band) and 5.05?5.90 GHz (WLAN band), respectively, and well as LTE bands. Both the experimental and simulated results of the proposed antenna are presented, indicating that the antenna is a good candidate for various 3GPP applications.
