Abstract
The circular sector patch antenna is studied in C-band (4 GHz - 8 GHz). In this paper, we present steps of designing the circular sector antenna then a comparison with a rectangular antenna in literature. High Frequency Structure Simulator (HFSS) software is used to compute the gain, axial ratio, radiation pattern, and return loss S11 of proposed antenna. Based on the designed patch antenna, many phased arrays will be simulated using HFSS. The impact of distance between element, number of element and phase will be checked. Obtained results are analyzed and compared with literature.
Highlights
Modern Wireless communication Systems require low profile, lightweight, high gain and simple structure antennas to assure reliability, mobility, and high efficiency
In our study we are interested in circular sector shape, because of their small size compared with other shapes like the rectangular and circular patch antennas and provide circular polarization which is desired in wireless communication
We demonstrate that changing feeding mode hasn’t a major effect on resonance frequency and radiation pattern
Summary
Modern Wireless communication Systems require low profile, lightweight, high gain and simple structure antennas to assure reliability, mobility, and high efficiency. A patch antenna is very simple in construction using a conventional microstrip fabrication technique [1,2,3,4,5]. It consists of a patch of metallization on a grounded dielectric substrate. They are low profile, lightweight antennas, most suitable for aerospace and mobile applications. In our study we are interested in circular sector shape, because of their small size compared with other shapes like the rectangular and circular patch antennas and provide circular polarization which is desired in wireless communication. The chosen rectangular antenna is designed by Pozar in [1]
