“…Although the angle of the arch that is formed by the two branches can be the third parameter for impedance matching in the case of circular meshed patches, it was found that the optimal coupling performance can be achieved when it is 60 • [15]. Other benefits of this feeding technique include low insertion loss in dual-port application [17] and improved gain and bandwidth [18]. While it is true that such a feed line may decrease the overall transparency of the antenna, the thick microstrip line can be placed on top of the cover glass above one of the gaps (G in Fig.…”

Abstract-This paper analyzes rectangular and circular patch antennas fabricated from meshed conductors and backed with solid ground planes. Because of the meshing, the antennas are rendered optically transparent, where the transparency is determined by the mesh geometry. It is found that although there is a compromise between the antenna's efficiency and the optical transparency of the meshed patch, it is possible to optimize the antenna by refining mesh lines to certain extent. The limiting factors for refining mesh lines include material handling and fabrication process as well as the increased line impedance when being refined, which accordingly causes loss in antenna's efficiency. A refined mesh with thin linewidth increases both antenna performance and transparency. Additionally, it is found that the reduction of certain mesh lines increases the optical transparency with minimal hindrance to the antenna's efficiency, leading to further enhancement to the see-through percentage. Although it is possible to refine mesh lines to improve the antenna's efficiency or gain, it is seen that there is a limit for such an optimization method. This limit is closer to the efficiency of a solid patch for a lower transparency, whereas it is lower for increased transparency. Cross polarization level was also examined, and there was no significant effect on such a parameter due to meshing.

The novel design of a T‐coupled circular microstrip antenna with H‐shaped aperture for active reflectantenna application is presented in this paper. The circular patch determines the frequency resonated; the H‐shaped aperture is used to obtain the responses of the desired 2.4–2.48 GHz ISM band and the T‐coupled feed line enhances the response of the band using the impedance‐matching technique. Meanwhile, the dual‐polarized ports of the T‐coupled microstrip antenna are developed for the active reflectantenna and applied to a corner‐wall structure. The antenna is capable of achieving high‐directivity gain, wide bandwidth, high isolation, and low cross‐polarization levels. © 2005 Wiley Periodicals, Inc.
