“…The detailed explanation on number of the current modes and mode numbers required on the feedline and patch are given in [1], [2] and [5]. The original code in the previous work has been validated by comparing with the measurements in [1], [2] and [6], for the Ka-and the Ku-Bands. Both of the codes were developed in C++ programming language on Linux system and the Gaussian Quadrature algorithm was used for the integrations.…”

Analytical evaluation of asymptotic part of the Green's function, in product with piece-wise sinusoidal, entire domain, and travelling wave mode basis functions, is presented. The Sommerfeld type double integral in spectral domain is solved and reduced into a single integral in spatial domain with very short integration range. The derived results lead to develop a computational efficiency improved code, which has been found 27 times faster than the earlier validated common method of moments code.Index Terms-Lens antennas, microstrip antennas, stacked microstrip antennas.

“…Due to its dependability of compactness, easy fabrication, low profile, light weight, portability, and low cost fabrication [2], microstrip antenna is very suitable for the requirement of satellite (spaceborne) [3] and air-borne applications [4,5]. Furthermore, microstrip antenna significantly has flourished in some field, for example, military [6], medical [7], and maritime [8] fields. Thus, the development of a circularly polarized (CP) antenna for X-band communication utilizes microstrip material.…”

This paper presents a novel Circularly Polarized (CP) microstrip array antenna with circular shape and slotted by an elliptical ring for X-band communication. This array antenna consists of 4 paths. Each patch is designed with a unique model, and the purposed antenna is mainly circular-shaped. An elliptical ring slot is set at the center of the circular-shaped patch. And a pair of triangle shapes employed as truncation factor is placed at the edge of the circular-shaped antenna. This microstrip array antenna is developed by 2 × 2 patches in a sequential rotation mode with relative phases 0 • , 90 • , 180 • , and 270 • . The total dimension of this array antenna is 60.92 mm × 60.92 mm. The simulated result shows a good agreement with minimum requirement. The center frequency of the antenna design is 8.2 GHz with low frequency at 8 GHz and high frequency at 8.4 GHz. The proposed antenna is produced under −10 dB S 11 of 21.9%, maximum gain of 12.47 dBic at the center frequency, and axial ratio bandwidth of 12.2% is obtained. Simulated result has been validated by fabrication and measurement, then the structure of the antenna design is fabricated on NPC-H22A with a thickness of 1.6 mm and dielectric constant of 2.17. Complete investigation and experimentation are presented in the next sections.

“…Global Positioning System (GPS), which is one of the most important tools, has been widely used for providing exact information of position and time for users, especially for users in marine applications such as marine surveying and offshore exploration [1][2][3][4][5]. Compared with the applications on land, the applications on sea are more severe for GPS antenna designs.…”

Abstract-In this paper, a method to broaden the beamwidths of a crossed dipole antenna is proposed. By introducing four parasitic strips around the crossed dipole antenna, the beamwidths of the crossed dipole antenna in the vertical plane are broadened effectively, making the patterns uniform over a wide frequency band. An Lband prototype, operating in the frequency range 1.1 GHz to 1.6 GHz, is fabricated and tested. The simulated and measured results show that the beamwidths at lower frequencies are broadened and uniform radiation patterns over the whole operating frequency band are obtained, making the crossed dipole suitable for wideband marine GPS (Global Positioning System) applications.
