“…In this section, the proposed antenna structure is compared with other antenna designs recently published. When compared with, this design has a higher relative bandwidth and smaller relative size (the ratio of true size to guided wave length), but the gain is lower. When compared with, the relative size is almost the same, but the gain and relative bandwidth are obviously higher.…”

A novel Antenna‐in‐Package with small size and low profile is designed based on Low Temperature Co‐fired Ceramic technology. In order to realize miniaturization and broadband in antenna part, a novel structure using double fractal antennas and air cavities is applied. A packaging cavity is designed for integrated with usable components and IC chips. The antenna operates at a center frequency of 2.4 GHz and the bandwidth is about 200 MHz. Its maximum gain is 5.6 dBi, and radiation efficiency is above 90% across the frequency passband. By adjusting the dimension parameters, a tradeoff between height and area can be made with its performance parameters constant, therefore the proposed Antenna‐in‐Package can easily adapt to different processes and performance.

“…The design specification and parameters of the antenna is presented in Table I. This antenna design is an improvement from the previous paper in [8] which it used single fractal radiation patch with four parasitic patches. The improvement in this design is to study the effect of array configuration by using stacked patch Minkowski fractal patch antenna.…”

In this paper, a 10.1 GHz fractal patch antenna using Low Temperature Co-Fired Ceramic (LTCC) Technology has been used. A Minkowski first iteration fractal micro strip patch antenna has been used in this design. However, a good agreement in terms of gain still did not achieved for X-band operation. To solve the problem, basic design is then be improve by using array concept to increase the antenna performances in terms of gain and bandwidth. A comparison between two types of antenna array is done between 2 by 1 and 2 by 2 design. A simulated result which is the gain of the antenna is increase from 10.02 dB to 13.51 dB for 2 by 2 antennas by using array concept and bandwidth of 99 MHz. From the result, it is shows that 2 by 2 array antenna design gives wider bandwidth and higher gain as compared with 2 by 1 array antenna.

“…In the same way materials permittivity and the thickness of the substrate will affect the surface wave loss. Therefore, the conductor and dielectric losses can be reduced by choosing the good conductor, substrate materials and hence increasing the antennas gain, the patch antenna gain could be increased additionally through the suppression of surface waves (Chen et al, 2009;Sukaimi et al, 2013;Kumar et al, 2007;Madhav et al, 2013). One of the simple methods is replacing the patch antennas substrate with air whose dielectric constant is equal to 1 or by a less dielectric constant material, which are well known to be suspended patch antennas.…”

Gain is an important parameter of the antenna through which the performance of the antenna is determined. Generally to increase the gain of the antenna, array configuration will be used but the overall size of the antenna will be increased. A method to enhance gain of a fractal antenna is investigated by partially removing the substrate surrounding the patch. The partial substrate removal reduces the losses due to surface waves. The effects of substrate removal in different configurations on the gain of the antenna are studied numerically and simulated. Compared to a conventional patch antenna, the antennas with partial substrate removal can enhance gain, for example, up to 2.7 dB. Furthermore, it is observed that the enhancement of gain is more due to the loss reduction of surface waves and dielectric substrate than increased patch size when the effective dielectric constant of substrate is lowered. Such a technique can be applied on designs, operating at higher frequencies where by surface wave and substrate losses are more significant.
