“…In recent several decades, photonic crystals are used in different antennas to enhance performance of bandwidth, gain, radial direction, decoupling, etc. The representative applications include low profile antenna, microstrip antenna, array antenna, slot antenna, high gain antenna and phased-array antenna [3][4][5][6][7][8][9][10]. To realize the special structure of photonic crystal antenna, MEMS is utilized to ensure accurate fabrication.…”

Abstract-An extremely wideband photonic crystal antenna is proposed with a very compact size of 16.6 × 26.6 × 0.9 mm 3 . The double-layer materials of silicon and glass are selected as the antenna substrate. The band gap performance of photonic crystals can decrease electromagnetic wave absorption of silicon substrate, restrain surface wave loss of antenna, and increase electromagnetic wave space radiation. Hence the periodical photonic crystal with square lattices is applied in upper silicon substrate. The glass substrate not only decreases effective dielectric constant of antenna, but also supports silicon substrate with photonic crystal. MEMS processes are used to realize photonic crystal antenna with plenty tiny through-holes. The simulated and measured results demonstrate that photonic crystal can effectively expand the working bandwidth of base antenna.

“…However, these techniques do not allow having a good performance in terms of impedance, directivity, and large wide band, hence the interest in the use of metamaterials [13], [14] to decrease the resonance frequency and maintain the performance of the antenna. Metamaterials, which were propounded by Victor Veselago in 1968, are also called lefthanded materials (LHM) because the vectors E, H, and K form a left-handed system [15], [16].…”

“…However, the antenna gain would decreases obviously. The other way was employing antenna array as the primary feed [10,12], but a complex feeding network would bring in loss and the gain improvement was very limited, especially in millimeter-wave. In [4], Feresidis and Vardaxoglou noted that a wide directivity bandwidth could be obtained if the gradient of reflection phase over the operation band was positive.…”

Abstract-A broadband Fabry-Perot cavity antenna (FPCA) operates at Ka band with high gain and dual-polarization is reported. The proposed antenna employed a double-sided complementary-circular partially reflective surface (PRS) to enhance the directivity bandwidth. A square patch coupled by two orthogonal slots and fed by two microstrip lines was applied as the primary feed to achieve dualpolarization operation. To further improve the impedance bandwidth and directivity, a series of metal vias were suggested to surround the primary patch. This FPCA design was verified by the measurements. The experimental results show that the common impedance bandwidth of the two ports for the reflection coefficient (S 11 ) below −10 dB is 2.5 GHz from 34 GHz to 36.5 GHz (7.1%), which covers the common 3 dB gain bandwidth of the two ports. At the center frequency of 35 GHz, the measured peak gains at the two orthogonal ports are 16.1 dBi and 15.1 dBi, respectively. The isolation between the two ports is higher than 30 dB within the bandwidth.
