Digital Audio Broadcasting (DAB) system is one of the high - definition radio with the ability to provide high audio quality and data - based services for stationary and mobile receivers. Digital Video Broadcasting (DVB) is the popular broadcasting standards that enable handheld receivers to receive high definition digital television transmissions. Orthogonal Frequency Division Multiplexing (OFDM) system is a digital multi – carrier modulation technique intend offers high spectral efficiency. The main aim set is to arrive as an efficient unified system for multipurpose wireless system that would cater to all existing standards. This paper presents the unified approach for designing an integrated antenna for DAB and DVB using OFDM system. In this paper DAB and DVB using OFDM system is designed individually and their performance is measured by Bit Error Rate (BER). Integrated antenna for DAB and DVB using OFDM system is designed and simulated radiation patterns are presented. The proposed unified approach produces the better BER performance and better gain as compared to individual standard design
