ABSTRACT

In this paper a miniature design for dual band antenna with integrated filtering realization for LTE-A (long term evolution advanced) system is presented. In the proposed investigation the ground plane and patch are defected by cutting different slots with different dimensions. Different shapes of slots are cut to get appropriate lower band (1880- 1920 MHz) and higher band (2570 to 2620 MHz) for which return loss is less than -10 dB. This slotted patch antenna employed for dual band operation provides satisfying filtering performance without using any extra filtering circuits. The antenna is designed to fit the specification of LTE –A bands (B38 and B39 bands). The proposed antenna offers improved radiation characteristics with good omni-directional patterns at both sampling frequencies in the E-plane (yz-plane) and the H-plane (xy-plane).These patterns are appropriate for application in most of the wireless communication like LTE and LTE-A. Gain of antenna is increased with frequency. Gain of lower band frequency is approximately -4.5db and 1.5 db for upper band frequency. The integration of the filter and the antenna leads to a reduction of size and weight.
