“…Nevertheless, the size of the low frequency RMSA becomes large and the bandwidth is small. Many techniques for obtaining both the compact and broadband antennas were published in the literature, such as high relative permitivitty substrates( r), shorting pins at appropriate position inside the radiating patch and etched slits etc... [1][2][3][4][5]. Advancements in the wireless communication field involve innovative RMSAs which provide dual or triple band to avoid using two or more antennas and that can also allow size reduction.…”

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.

“…Recently, annular-ring microstrip antenna (ARMSA) has drawn many scholars' attention [4][5][6][7][8][9]. For the ARMSA, its patch size is smaller than the traditional square and circular patch antenna when operated at the fundamental mode (TM 11 mode).…”

“…Some techniques have been reported to solve the problem. In [4], a stacked annular ring coupled to a shorted circular patch was presented which offered a large impedance bandwidth and low crosspolarization levels. In [5], the author adopted microstrip line as an impedance transformer to realize impedance matching with 50 Ω, and the transmission loss caused by the very narrow microstrip line has to be considered carefully.…”

A novel design of circularly polarized (CP) annular-ring microstrip antenna (ARMSA) working in TM 11 mode is presented. The CP radiations of the proposed antenna are implemented by a 90 • branch-line hybrid coupler placed at the inner part of the ARMSA. Since the ARMSA has narrow bandwidth and high-input impedance, a circular parasitic patch suspended above the ring is employed for not only improving the impedance matching and bandwidth, but enhancing the performances of axial ratio (AR). Due to the utilizing of parasitic patch and circular hybrid, the measured results are shown to attain a 10-dB return loss bandwidth of 31.2% (1300-1780 MHz) and a 3-dB AR bandwidth of 19.2% (1360-1650 MHz) respectively. The CP gain is 8.2 dB at 1.575 GHz. The proposed antenna is low profile and has a simple structure, therefore, it can be a good candidate for GPS portable terminal applications.

“…This Letter proposes a rectangular microstripline-fed circular printed slot antenna, which has similar radiation pattern properties, with the advantage of bandwidth wider than that of conventional circular slot [8 -10] and annular printed slot antennas [6,7]. In this case, many design parameters of the proposed antenna lead to good impedance matching in a wide frequency band.…”

A large‐band rectangular‐shaped microstrip‐fed circular slot antenna is studied in this Letter. In this case, many design parameters of this antenna lead to good impedance matching in a wide frequency band. Although the use of a high‐relative‐permittivity (εr = 4.3) substrate usually restricts the operation bandwidth, the measured bandwidth is from 2.277 to 9.272 GHz, which is approximately 124.6 % (VSWR ≤ 2.0). The experimented data for the impedance loci and the radiation patterns of the antenna are also described. © 2002 Wiley Periodicals, Inc.
