“…The substrate's Dielectric constant ( ), its operating frequency (𝑓 ), and the height of the substrate (h) from the ground plane are the three design parameters of a microstrip antenna, and they affect the patch's dimensions, radiation pattern, return loss, and other parameters [3]. The problem of effective dielectric constant of multilayer structures for antenna applications has been studied by a number of researchers [4,5,11], to obtain expressions for the effective filing fractions and effective dielectric constant. In this work we have based on Wheeler's [8] transformation from the physical 𝑧 plane to the complex flux-potential 𝑔 plane ( 𝑔 𝑢 𝑗𝑣 ), these areas are depicted in Figure 2.…”

“…The starting of the calculation has been made to have a resonance frequency at 28 GHZ, and for the bottom substrate is rogers RT3003 with 0.5 mm thickness with dielectric constant of 3 and loss tangent equal to 0.001, for this design, the top substrate is made of dielectric foam with a thickness of 0.254 mm and a dielectric constant of (εr=1). For the calculation of the basic antenna elements (width, length, feed line) we have used the formulas that are already published on the work [11].…”

In this paper, we investigate an aperture-stacked patch microstrip antenna with three slots in a circular shape that feeds the antenna in order to have an improvement in its performance. The structure optimized and analyzed in this study has an upper substrate of foam dielectric material with a thickness of 0.254 mm and a dielectric constant of 1, a lower substrate of rogers RT3003 with a thickness of 0.5 mm and a loss tangent of 0.001. A cost-effective technique of improving the front-to-back ratio used in this work is to install a reflector which take shape like an aperture-stacked, printed on a thin dielectric layer (0.254 mm) with a dielectric constant of 4.4 and a loss tangent of 0.025. As a result of using the proposed reflector to increase the directivity, the front-to-back ratio of the proposed antenna improved by about 10 dB. With 7.79 dB and matching S11 -40 dB, the structure provides an intriguing gain value.

This chapiter starts with a general definition of the antennas. The next parts will talk about a microstrip antenna from the side of the double band in order to get an antenna that can do both reception and emission as well as developing the azimuth and angular resolution. This chapter has also introduced an antenna that separates the feeding part from the rayonnant one in an effective way that can enable us to develop the abilities of the radar antenna. Besides, it would also cope with the mechanic relation of the antenna. Another work has been presented to make electronic scanning more effective and faster. This would allow us to get rid of mechanic circulation by using butler matrix. Developing the antenna from the angular resolution has also been presented through widening the bandwidth by DGS technique and widening the reach via using the antenna array. Among the biggest problems are the surface waves and mutual coupling that present significant challenges to the designer because of their graduation of the antenna performance especially in the radar system.
