<span>This paper presents a bandwidth enhancement of dual-band bi-directional rectangular microstrip patch antenna. The novelty this work lies in the modification conventional microstip antenna by using combination two techniques: complementary split ring resonator (CSRR) and defected structure (DPS). was studied investigated via computer </span><span>simulation technology (CS...

Transmission line structure based on substrate integrated waveguide (SIW) loaded with new structure of octagonal complementary split ring resonator (CSRR) has been proposed. The SIW loaded CSRR pair is used in dual/quad octagonal structure to design dual band pass filter (single and double pole) with improved performance characteristics. The proposed band pass filter (BPF) yields two passbands ...

A highly reliable and efficient communication system is needed for a vehicle to navigate drive the destination without human control (known as an autonomous or self-driving vehicle). In this work, we consider various parameters antenna design, ensuring amongst vehicles infrastructure. Specifically, type of antenna, method used, operating frequency, substrate (with thickness permittivity), size ...

This paper introduces a decagonal C-shaped complementary split-ring resonator (CSRR) textile-based metamaterial (MTM). The overall size of the proposed sub-wavelength MTM unit cell is 0.28λ0 × 0.255λ0 at 3 GHz. Its stopband behaviour was first studied prior analysing negative index properties MTM. It worth noting that in this work unique way experiments were completed. For both simulations and ...

In this review article, different structures of monopole antennas based on metamaterial concepts which have been developed for various wireless applications are presented. The antennas designed for wireless applications must be broad band, low profile, small size and have better performance. Monopole antennas embedded with Artificial magnetic conductors (AMC), Electromagnetic band gap structure...

Over the years, Cognitive radio technology has dramatically influenced wireless systems in which antenna plays a significant role for interviewing spectrum sensing and underlay operations. An ultra-wideband (UWB) with extended dual notch band feature is proposed this work to meet requirements of cognitive radios without interference from crowded spectrum. The consists stair-stepped rectangular ...
