|A novel compact composite right/left-handed (CRLH) substrate integrated waveguide (SIW) based leaky wave antenna (LWA) is proposed. Mushroom-inspired unit cell is utilized to achieve CRLH transmission property as well as energy leakage. Periodically loaded metallic vias, which act as an internal 1 : 2 power divider, are along the center line of the SIW structure, leading to a compact antenna size. The LWA can be regarded as an antenna array whose two elements are excited by two newly produced quasi-TE 10 modes, respectively, and therefore, the antenna peak gain is enhanced. Good agreements are obtained between the simulated and measured results. Continuous beam scanning feature indicates that the proposed design is a balanced frequency scanning work operating in Ku-band.

|An ultra-compact band-pass (cid:12)lter is presented in this paper. The (cid:12)lter is designed to operate in the medical implants communication service (MICS) band ranging from 401 MHz to 406 MHz. The (cid:12)lter is designed on a Rogers RT/duroid substrate with " r = 2 : 94 and tan (cid:14) = 0 : 0012. The overall size of the proposed (cid:12)lter is only 30 : 6 mm (cid:2) 18 : 5 mm (0.058 (cid:21) g (cid:2) 0 : 035 (cid:21) g ), making it suitable for compact, portable devices. An equivalent circuit model is also proposed for the analysis of the (cid:12)lter geometry. From the circuit model, it can be concluded that the (cid:12)lter exhibits the characteristics of a dual-composite right left-handed (D-CRLH) transmission line. This is also con(cid:12)rmed from the dispersion characteristics. The salient features of the proposed (cid:12)lter include ultra-compactness at low operating frequency, harmonic suppression of 3.7 times of the passband frequency, fractional bandwidth of 4.45%, and good roll-off rate of 297.6 dB/GHz in the lower stopband and 116.4 dB/GHz in the upper stopband.

|A new miniaturized patch antenna based on a metal strip is proposed in this paper. The antenna is designed by adding a middle metal strip layer to the substrate of a traditional rectangular patch antenna. By increasing the length of the metal strip, the working frequency of the patch antenna can be continuously reduced without signi(cid:12)cantly impacting the radiation pattern. The simulation results indicate that as the metal strip length increases from 5 mm to 25 mm, the working frequency of the patch antenna decreases from 2.39 GHz to 1.84 GHz, and its gain decreases from 6.72 dBi to 5.4 dBi. Two antenna samples with metal strip lengths of 5 mm and 20 mm are fabricated. The experimental results indicate that their working frequencies are 2.64 GHz and 2.43 GHz, respectively. And the radiation patterns of two antennas are consistent with the simulated results. All results con(cid:12)rm the effectiveness of the proposed miniaturization method.

|In this paper, we investigate the propagation behavior of electromagnetic waves through coaxial optical (cid:12)ber bounded with DB-boundaries. For this purpose, an eigenvalue equation is derived by using suitable DB-boundary conditions to determine the allowed values of propagation constant (cid:12) for each propagating mode. Moreover, we have analyzed the electric (cid:12)eld and power distribution patterns through coaxial optical (cid:12)ber for different propagating modes and dimensions, respectively. Our results show that small dimensional guide con(cid:12)nement remains maximum close to the lower interface of the guide, whereas, for larger dimensions, it shifts toward the upper interface. Investigations show that high power is con(cid:12)ned by H 12 mode compared to H 11 mode, and, therefore, shows contrary behavior compared to commonly used (cid:12)bers.

|In this article, a 15 (cid:2) 20 mm 2 arbitrary-shaped antenna is built. The same is extended to a 2 (cid:2) 2 MIMO antenna with size 32 (cid:2) 20 mm 2 . It covers two bands. Band-1 covers 3{4.44 GHz, and band-2 covers 5.32{11.1 GHz. In this case, a circular neutralization structure is used to lessen the mutual coupling between the two ports. The ECC, DG, CCL, and radiation pattern are used to demonstrate how well the MIMO antenna performs. Also, it has been noted that there is good agreement between simulated and measured outcomes.

|This paper presents a coplanar waveguide (CPW)-fed tri-mode hybrid antenna that is suitable for quad-band applications. The antenna design is compact, measuring only 30 (cid:2) 30 mm 2 , and consists of a zeroth-order resonator (ZOR) antenna, a torch-shaped monopole antenna, and a T-shaped slot antenna. The most signi(cid:12)cant feature of this design is its ability to provide three independent working modes, making it a hybrid antenna. By incorporating a Composite Right/Left-Handed Transmission Line (CRLH-TL) unit cell, the (cid:12)rst mode is excited as a ZOR antenna, corresponding to the lowest resonance at around 1.57 GHz. The second mode relies on the torch-shaped monopole antenna with two resonances at about 2.5 GHz and 3.5 GHz. The third mode employs the T-shaped slot antenna with a resonance at around 5.5 GHz. Experimental results demonstrate that the proposed antenna exhibits a wide and multi-band behavior with impedance bandwidths of 60 MHz (1.56{1.62 GHz), 210 MHz (2.30{2.51 GHz), 370 MHz (3.40{3.77 GHz), and 1100 MHz (5.05{6.15 GHz). This antenna can not only support the current GPS/WLAN/WiMAX systems but can also be considered as one element of a multiple-input-multiple-output (MIMO) antenna array for the (cid:12)fth-generation (5G) mobile communication in the sub-6 GHz frequency range.
