“…The advantages of proximity coupled feeding method include higher bandwidth, better impedance matching and lower spurious radiation. In the proximity coupled feeding method, radiating patch is positioned on the top of the upper substrate and feed line is positioned in between two dielectric substrates [18]. Electromagnetic field coupling occurs between feed network and the patch.…”

This paper presents a novel method for the design of truncated microstrip patch antenna with Defected Ground Structure (DGS) based on Double Looped Complementary Split Ring Resonator (CSRR) arrays for enhancement of bandwidth. The proposed antenna is suitable for WLAN/Wi-Fi, RFID applications. A truncated microstrip patch antenna without DGS was initially designed for a resonant frequency of 2.86GHz having a bandwidth of 95.6MHz. By integrating a new Double Looped CSRR array (DLCSRR) structure on the ground plane, resonant frequency of the antenna is shifted to 2.47GHz and also the bandwidth is enhanced to 202.5MHz. By implementing DLCSRR array structure on the ground plane size reduction and bandwidth enhancement of 52.79% is achieved. The performance of truncated microstrip patch antenna with DGS based on Double Looped CSRR array structure was also compared by replacing conventional proximity fed microstrip patch antenna with the same physical size. The conventional proximity coupled microstrip patch antenna is designed for a resonant frequency of 2.26GHz with a lower bandwidth of 23.3MHz. The antennas were designed using CST simulation software. The measurement results show a good agreement with simulated results

“…They have been employed as radiating or receiving elements in a wide range of microwave systems, such as radars, navigation, mobile communications [6] and wireless biotelemetry [7]. In microstrip antenna design, it is important to ascertain the resonant frequency of the antenna accurately because microstrip antennas have narrow bandwidths [8][9][10][11][12] and can only operate effectively in the vicinity of the resonant frequency. As such, a theory to help ascertain the resonant frequency is helpful in antenna designs.…”

These expressions are obtained based on genetic algorithm and the data base is generated using moment method (MOM). The proposed model is very simple, fast, and valid for an entire range of permittivities and thicknesses of two-layered substrate. The present model has been validated by comparing our numerical results obtained for the resonant frequencies with measurements. Finaly, the effect of the two-layered substrate on the resonant charateristics of the circular microstrip patch antenna has been presented.</p></td></tr></tbody></table></td></tr></tbody></table>

“…Microstrip patch antennas are used in many applications and fields due to its various advantages such as low weight and profile [3], mechanical robustness and fluency of manufacture [4]. However, the radiation characteristics of the antenna degrades when we rise frequency up to the millimeter wave band [5], commonly called Extremely High Frequency band (EHF).…”

<p>This paper presents an enhanced Quadri-band microstrip patch antenna, using defective slots in the ground plane, designed to operate in the millimeter wave band, formulated using cavity model and simulated by an EM-simulator, based on finite element method: HFSSv15 (High Frequency Structure Simulator). The proposed antenna incorporates two symmetric patterns of “U” shaped slots with an “I” shaped slot engraved in the middle of the ground plane. The resulting antenna has four frequency bands; the first resonant frequency is located in the Ka band, at about 27Ghz, the second at nearly 35Ghz, the third at 41Ghz and the last one at 51GHz. Those resonant frequencies could be shifted by tuning the slots dimensions introduced if the ground plane of the proposed antenna .</p><p> </p>
