Delivery Medium

In many countries, terrestrial broadcasting is the main delivery medium for television. In this paper, we propose a small-volume practical receiving antenna. Our design consists of a linear array of three vertically placed patch antennas which increase antenna gain. The antenna has a double-dielectric substrate (FR4 + air) in order to increase efficiency and bandwidth. In this paper, we also discuss simulations and practical results, and demonstrate that the proposed double-dielectric microstrip antenna is a viable design choice for digital terrestrial TV (DTT) reception. The designed antenna reached a gain of 10.5 dBi at the desired central frequency of 754 MHz.

Good Agreement

ABSTRACTSemi-insulating (SI) silicon carbide (SiC) was evaluated as a candidate material for dielectric substrate for patch antennas suitable for monolithic antenna integration on a SiC semiconductor chip. Computer simulations of the return loss were conducted to design microstrip patch antennas operating at 10 GHz. The antennas were fabricated using SI 4H-SiC substrates, with Ti-Pt-Au stacks for ground planes and patches. A good agreement between the experimental results and simulation was obtained. The radiation performance of the designed SiC based patch antennas was as good as that normally achieved from antennas fabricated using conventional RF materials such as FR4 and Rogers. The antennas had the gain around 2 dBi at 10 GHz, which is consistent with the conventional antennas of a similar size.

Triangular Patch

Modern Wireless communication Systems need high gain, light-weight and straightforward structure antennas to assure high potency, quality and additional dependableness. A patch antenna is incredibly easy in building, employing the fabrication techniques of standard Microstrip. It consists of a blotch of metal on a grounded dielectric substrate which forms a light-weight antenna best suited for mobile and aerospace applications. Patch antennas have developed significantly throughout preceding years and plenty of their limitations are overcome by changes in its design and fabrication techniques. The conducting patch may well be of any form however rectangular patterned configuration is used foremost. In this study we tend to have an interest not solely in rectangular however comparison of it with circular and triangular patch antenna styles. The objective here is to analyze the results of various patches.
