“…Mobile telephony systems for example, allow portable devices compliant with GSM900/DCS1800/ UMTS2000 technologies and the same devices will also link users to WLAN networks based on 802.11 standards (2.4/3.6/4.9/5/5.9GHz) specifications. Hence, it is of great interest to develop patch antenna with multiple resonances [4][5][6][7].Many researchers have made huge efforts to design slot/slit based antennas on the radiating patch and ground plane, which can be used for multiband operations [8][9][10][11][12][13][14].Reconfigurable antennas are still attracting many researchers for designing multiband antennas [15][16][17].Metamaterials are the promising new candidates for designing multiband antennas [18][19][20].Fractals have been investigated for multiband antenna operations [21,22].Stacking of antennas for multiband operation has also been investigated [23,24].…”

A Compact Corner Split Ring with Split C Slot Rectangular Microstrip patch Antenna (CCSR-SCS) fed by a 50 Ω microstripline is discussed. A Corner split ring with C shaped slot has been etched in rectangular microstrip antenna. The slot increases the length of the surface current for the dominant mode TM 10 leading to the decrease in resonance frequency. The size reduction along with proposed antenna Hexaband is obtained with the antenna and it is best suited for wireless communication. The proposed work is simulated using 3DEM of Mentorgraphics. The results show that Hexaband with compactness is achieved.

“…An axial ratio bandwidth of more than 7% was achieved by using a 2 × 2 single-fed CP corner truncated patch array [20]. Multiband circular polarization can be achieved in a three-layered antenna structure using corner truncation, embedding slits, and inclined slots [21]. Another method to generate CP waves is using a 4 × 4 substrate-integrated waveguide feed to a slot-coupled rotated strip with a metal topped via fence fabricated using LTCC technology [22].…”

In this paper, a high gain wideband circularly polarized (CP) microstrip antenna is presented for broadband operation. The proposed structure comprised of a partially grounded printed monopole antenna loaded with a split ring resonator and a metallic reflector. By using the metallic reflector surface underneath the patch radiator results in the reflected waves in the same phase with main lobe radiation, thereby improving the gain and it also acts like a secondary radiator to generate wideband CP behavior in the proposed design. A gain enhancement of 4.3 dBi is achieved in the operating frequency band as compared with the design without a metallic reflector. The maximum gain achieved in the presented method is 8.6 dBic over the entire operating range. The proposed design shows a wideband behavior ranging from 4.30 to 9.10 GHz with the 10-dB impedance bandwidth of 71.64%. In addition, the proposed design yielded a broadside right hand CP radiation with a 3-dB axial ratio bandwidth of 33.88% from 4.98 to 7.01 GHz. The proposed antenna is fabricated and experimental results on reflection coefficient, gain, axial ratio, and radiation patterns concede well with simulation results.

A novel shape penta-band microstrip patch antenna is presented in this paper. The proposed antenna shows five operating frequencies and can be used for various wireless applications, i.e. 2.58 GHz for non-direct line of sight, wireless Internet service providers, and compatible with Navini Networks; 3.17 and 3.42 GHz for WiMAX; 4 GHz for C-band application such as weather radar systems; and 5.3 GHz for higher WLAN. Very small frequency ratios of the values 1.2286, 1.078, 1.169, and 1.325 are achieved between two consecutive resonant frequencies. Antenna design techniques for achieving five bands are presented and discussed step by step. The analysis is done by Ansoft HFSS v.15, and results are verified with experimental results of fabricated prototypes.
