“…When the AMC structure is located under the incidence of a plane wave, it exhibits a reflection coefficient of +1 at a specified frequency [13]. It means that the phase of the reflected wave is 0 • compared to that of the incident wave, which enables the AMC surface to produce constructive superposition of the incident and reflected waves [14]. The frequency band, in which the reflection phase ranges from −90 • to +90 • , is defined as the in-phase band of the AMC structure [4].…”

A low-profile and broadband slot antenna with artificial magnetic conductor (AMC) surface is designed for X and Ku communications. Loaded with evolved C-shaped branches, the proposed coplanar waveguide (CPW)-fed slot antenna, which consists of two radiating slots, exhibits wide impedance frequency band performance. The presented AMC, the unit cell of which is made up of two central hexagonal circles with six rectangle branches, operates in a wide in-phase reflection frequency band ranging from 6.0 to 13.94 GHz (79.64%) at the reference plane 4 mm above the AMC surface. An AMC surface composed of 8 × 10 AMC unit cells is located under the slot antenna with a distance of approximately 0.107λ (λ denotes the free-space wavelength at 8.0 GHz), which improves the radiation and impedance match properties of the broadband slot antenna while maintaining low profile. A prototype of the proposed slot antenna with AMC surface is fabricated and measured. Measured results show that the composite antenna achieves a wide impedance bandwidth from 7.64 to 14.58 GHz (62.47%). The measured peak gain is up to 10.26 dBi, and the maximum cross-polarization level is −17.5 dB for both E and H planes. Good agreements between the measured and simulated results validate good performance of the presented slot antenna within the desired frequency band.

“…However, AMC suffers from its narrow operating bandwidths. Previous literature report bandwidths of 15.4%, 17.5%, 15%, 7.6%, 24%, 11%,, and 20.7% . These metasurface‐incorporated beam‐reconfigurable antenna from previous works are limited in terms of gain (less than 8 dB) and its maximum tilt angle (less than 45°), especially when implementing PIN diodes …”

“…One of the most recent and effective methods to improve the antenna performance is by incorporating metasurfaces in antennas. 1,[19][20][21] These metasurfaces include electromagnetic band-gap (EBG), 22,23 high impedance surface (HIS), 22 artificial magnetic conductor (AMC), [23][24][25][26][27][28] and reactive impedance substrate. 29 The AMC is a type of periodic structure which has special electromagnetic characteristics and capable to work as a perfect magnetic conductor (PMC) or HIS.…”

A beam‐reconfigurable crescent array antenna with AMC plane is presented for application at 9.41 GHz. The unit cell of the AMC plane is modeled based on a square patch integrated with rectangular ring slot with mirrored C‐shaped structures, placed between two layers of Taconic TLY‐5 substrate and located near to the main radiating element. The presented AMC design is achieved an operating bandwidth of 2.82 GHz (30%) with a center frequency of 9.41 GHz. It is found that the AMC plane can reduce the thickness of the structure in comparison to the use of a conventional ground plane, which leads to the overall compactness size of the proposed antenna of 1.1λ × 2.57λ. Moreover, through the implementation of 12 × 4 AMC unit cell, the proposed antenna improved its performance with a maximum gain and total efficiency of 10.5 dB and 97%, respectively. Meanwhile, the antenna reconfigurability is realized by integrating RF MEMS switches on its right and left arm symmetrically. The presence of a T‐shaped Yagi‐Uda‐like parasitic further widened the beam steering angle to ±63° via mutual coupling. The obtained results demonstrate a good agreement between the simulation and measurement and have a huge potential for development of X‐band radar.

Consistent with the SoP concept, AiP is an antenna that is realized on the package of the driving circuit [2]. There are many advantages of AiP that are beneficial for RF systems, the most prominent being the ability of realizing multilayer (vertically integrated) antennas that reduce the overall size of the system. Further, no separate printed circuit boards (PCB) for antenna realization or connections to an external antenna board are required, increasing compactness and cost savings. Finally, efficient antennas can be realized in low loss packaging technologies, particularly at mmWave bands. These aspects are discussed in detail in the coming sections. Low-temperature co-fired ceramic (LTCC) is one of the mainstream technologies for AiP designs. This chapter focuses on AiP designs in LTCC technology. Before moving on to details of AiP design, LTCC technology is introduced in the next section. Section II LTCC Technology LTCC is a multilayer ceramic tape system, which has recently gained popularity not only as a packaging technology but also as an efficient medium to realize passive components. In this section, we first briefly introduce the LTCC technology and then discuss the advantages and issues related to this technology. Later parts of the chapter focus on the LTCC process flow in detail. Finally, we list the major LTCC material suppliers and worldwide service foundries as a quick reference guide for readers.
