Dalia Sadek, Heba A. Shawkey, Abdelhalim Zekry . Passive Front End for LTE TDD Transceiver. International Journal of Computer Applications. 116, 8 ( April 2015), 6-11. DOI=10.5120/20354-2542
In this paper, a passive front end for a 3GPP Long Term Evolution (LTE) TDD transceiver comprising a microstrip antenna and filter is presented. The proposed antenna and filter operates in the LTE band 36 (TDD) which extends from 1930MHz to 1990MHz. A patch antenna and Hairpin filter is fabricated with a total area of 43x36mm2 for the antenna and 38. 6x32. 16mm2 for the filter. The proposed devices are fabricated using FR-4 material substrate and the measuring results show good agreement with the simulation results. The fabricated antenna has 2. 67dBi directivity, 1. 242dB gain, a minimum return loss of -31. 85dB at resonant frequency 1950MHz and 150. 3 MHz bandwidth at 6dB return loss, while the filter has -3dB BW of 90MHZ, a center frequency of 1950MHz and a fractional bandwidth of 4. 615%.
