This paper describes a novel design of Minkowski and Meander curves based hybrid fractal antenna for mobile devices used for communication in delay tolerant networks, wireless sensor networks and mobile adhoc networks. Meander curve improves the impedance bandwidth. Minkowski fractal curve gives its contribution to make antenna multiband. The proposed antenna resonates at five frequencies 1. 98, 5.94, 10.61, 12.73, 14.85 GHz. Prior to fabrication, better performance parameters such as return loss, radiation pattern, gain, current distribution, impedance, VSWR are achieved. The maximum bandwidth 2.83 GHz and gain 9.0 dB at 2.4 GHz are achieved. The proposed antenna can be used for various applications like Bluetooth, Wi-Fi, Wi-Max, Wi-Bro, AWS, GPS, S-DMB, WLAN 802.11b/g and DTH services etc. Simulated and measured results are compared and are found in agreement with each other.

In this work, a review has been presented on filter designs based on microstrip technology with the implementation of metamaterials. It briefly describes the properties of various types of resonators that behave as Left handed materials. Some of the implications of SRRs, CSRRs and other structures in filter design have also been discussed. General TermsMetamaterials in microstrip filters. KeywordsMetamaterials, microstrip filter, split ring resonator, complementary split ring resonator.
