Metamaterial-based design of microstrip antennas and other microwave structures have gained enormous popularity worldwide among researchers. The complementary split ring resonator (CSRR) is one of the most commonly used metamaterial structures in this direction. The CSRR structure yields a negative value of its effective permittivity at a narrow band near its resonant frequency. CSRR structure was initially proposed as a notch filtering element in microstrip transmission lines because of the negative permittivity. Later, the CSRR structure found its use in antennas and other microwave applications. The CSRR structure is reported to enhance the performance of a microstrip antenna in terms of its gain and bandwidth. In addition, CSRR structure is also used in the design of dual band antennas and antennas with integrated filters. This chapter deals with the practical design aspects relative to these applications of CSRR structures.

Dual Band Antenna

This paper describes dual-band patch antenna. The dual-band operation is obtained by embedding a pair of Lshaped slots. Dual band antenna can reduce the size of antenna 40%, comparing with rectangular microstrip antennas on normal dielectric substrate, and have wider bandwidths for both bands. In this paper L-shaped slots patch antenna with length L= 25.74 mm and width W = 31.20 mm fabricated based on availability of Rogers Duorid 5880 dielectric material and a prototype antenna is developed. The dielectric constant of Rogers Duorid 5880 material is e= 2.2 having thickness h = 0.16 mm and copper thickness is 35 microns using a coaxial feeding method for dual band operation. The prototype antenna is operating in S band frequency range.
