A Passive Front End of Radio Transceivers for LTE Bands

Software defined radio implementation is required for LTE (Long Term Evolution) radio transceivers. An SDR (Source Demand Routing) consists of an rf front end and a Digital Processor Platform (DSP). This paper is devoted to the design and implementation of the passive part of the front end; the antennas and bandpass filters. It presents the design of two microstrip patch antennas and a third order parallel coupled band pass filter with defected ground structure that can be used in cellular communication applications, especially in LTE. The two antennas cover LTE network bands.
