This paper is aimed at developing a blind hole substrate slotted microstrip patch antenna for x-band applications. The proposed antenna has been designed using Roggers RT5880 (lossy) substrate of dielectric constant of 2.2 sandwiched between copper patch and ground plane. The propounded antenna has been devised and simulated in CST Microwave Studio 2014. This antenna resonates at frequency of 10.45 GHz with the minimal return loss of-55.30 dB, high gain of 8.02 dB and directivity of 8.50 dBi. The proposed antenna works for all frequencies from 8-12 GHz resulting in a huge bandwidth of 1.1 GHz (9.99 GHz-11.09 GHz). Bandwidth enhancement of 50 percent is observed in the proposed antenna as compared to the existing antenna. The proposed antenna provides this huge bandwidth with a compact size. The designed antenna can be suitably employed for all X-Band (8-12 GHz) applications including Radar and satellite communications, weather monitoring, military communications, satellite to earth downlink, earth to satellite uplink, radio determination and ultra-wide band applications.

A compact circularly polarized antenna having x-slot in the parasitic patches have been proposed in this article. Four driven patches which are capacitively loaded with the help of the feeding loop and four parasitic patches which generate circular polarization because of the sequentially rotated structures are noticed in the proposed modal. With combination of the CP mode with the feeding loop we can observe the broadened axial ratio bandwidth. Comparative analysis has been observed for each side facing driven elements and side and edge facing parasitic elements with X-slot have been observed. The proposed antenna works at the bands of 5.04-5.83GHz and 6.34-6. 81GHz which works for WLAN application. The proposed modal and its iterations have been analyzed using ANSYS EM Software. The results show an enhanced impedance bandwidth of 22 percent and axial ratio bandwidth of over 15percent has been noticed in the proposed modal. A constant gain has been noticed all over the analyzed modals.

“…At the moment, the D-band frequency range 141 to 148 GHz is proposed for back-haul point-to-point relay stations and thus, several D-band Grid Array Antennas (GAA) have been developed and characterized for this purpose lately [1][2][3][4][5][6].…”

“…In some cases Liquid Cristal Polymer (LCP) is used [1] and in some cases Low temperature Co-fired Ceramics (LTCC) [2][3][4][5][6]. A cost benchmark on these two antennas has shown that, in small volume production, counting volumes of 500 antennas, the two solutions are very similar in cost.…”

International audienceA medium-gain Grid Array Antenna (GAA) is developed and manufactured in ESL41110, a low εr Low Temperature Co-fired Ceramics (LTCC) from ElectroScience Laboratory. The antenna dimensions are 12 mm × 12 mm × 0.3 mm and it has a measured impedance bandwidth from 135 to 142 GHz, with a boresight maximum gain of 7.96 dBi and vertical beams. In order to realize this antenna, new LTCC fabrication steps had to be developed and qualified in the in-house procedure, including laser ablation of gold in the green state as well as after sintering
