“…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.
