This article proposes a microstrip bandpass filter patch antenna for remote access, particularly for vehicular applications. The antenna comprises split ring resonator (SRR) defected ground structure. The antenna design and filter are integrated to collaboratively work as filtenna (integrated filter antenna) for enhanced performance by reducing the total power consumption in the system. The objective of this paper is to carry out a detailed study of the effects of SRR parameters on the proposed filtenna. The investigation is carried out on the width of the slit opening of the SRR slot and the rotation of the inner square shaped ring structure in clockwise direction. The proposed filtenna is designed to provide a tuneable frequency operation. Simulation is performed on high frequency structural simulator which demonstrates good output response making filtenna design suitable for intelligent vehicular communication, particularly dedicated short-range communication-based applications at 5.9 GHz band and wireless local area network applications. The proposed filtenna is smaller in size, has low insertion loss, displays high selectivity and exhibits brilliant out of-band execution.
