|This letter presents a compact ultra-wideband circularly polarized (CP) crossed-dipole antenna with enhanced axial-ratio beamwidth (ARBW) and half-power beamwidth (HPBW). It consists of four modi(cid:12)ed arms which are fed by vacant-quarter phase delay rings to excite CP radiation. Four parasitic elements are utilized rotationally between the dipoles and the re(cid:13)ector. Not only does inducing vertical currents on the parasitic patches excite additional impedance resonance to realize an ultra-wideband operating, but also reinforced radiation is obtained to improve the ARBW and HPBW. The experimental results show that the proposed antenna realizes a (cid:0) 10 dB impedance bandwidth of 134.3% and a 3 dB axial-ratio (AR) bandwidth of 115.0%, while holding a compact volume of 0.25 (cid:21) L (cid:2) 0 : 25 (cid:21) L (cid:2) 0 : 09 (cid:21) L ( (cid:21) L : wavelength at the lowest operating frequency). Furthermore, an HPBW and ARBW of more than 110 ◦ and 160 ◦ are realized within a broad operating band of 67.5% and 55.0%, respectively.
本文提出了一种具有增强轴比波束宽度(ARBW)和半功率波束宽度(HPBW)的紧凑型超宽带圆极化交叉偶极子天线。它由四个模臂(cid:12)组成，由空四分之一相位延迟环馈送以激发CP辐射。四个寄生元件在偶极子和re(cid:13)矢量之间旋转利用。在寄生片上诱导垂直电流，激发附加阻抗共振，实现超宽带工作，并获得增强辐射，提高ARBW和HPBW。实验结果表明，该天线实现了(cid:0) 10db阻抗带宽为134.3%，3db轴向比(AR)带宽为115.0%，同时保持了0.25 (cid:21) L (cid:2) 0: 25 (cid:21) L (cid:2) 0: 09 (cid:21) L ((cid:21) L:最低工作频率波长)的紧凑体积。此外，HPBW和ARBW分别在67.5%和55.0%的宽工作频带内实现了110°和160°以上。

|In this paper, a wide harmonic suppression (cid:12)ltering antenna with high selectivity is designed. The (cid:12)ltering antenna adopts dual-layer structures. By introducing four parasitic patches around the top driven patch, the impedance bandwidth is widened. Moreover, the current directions on the driven patch and parasitic patches are opposite in some frequency, so that radiation null is introduced. In addition, a rectangular split ring DGS is etched in the middle of the ground plane, a lower sideband radiation null is introduced. Two sets of dumbbell-shaped defected ground structures are etched on the ground plane of the intermediate layer. The high-order harmonics are suppressed, and another radiation null is introduced. The experimental results show that the antenna operates at 2.46{2.66 GHz; the relative bandwidth is 7.8%; the peak gain is 3.8 dBi; and the S 11 is more than (cid:0) 3 dB at 3{13 GHz.

|A (cid:12)ltering dielectric resonator antenna (FDRA) using an inductive CPW (coplanar waveguide) feed structure is proposed. Simultaneously, a pair of slotline stubs are respectively loaded on the signal line and ground of the CPW feed structure, which is used to generate radiation nulls near the edges of the passband. Furthermore, the two radiation nulls can be controlled independently by adjusting the length of the loaded two pairs of slotline stubs. In addition, it is interesting that TE 111 mode is split due to the different loading effects of slotline stubs in feed network, thereby three resonances in the passband are formed. Finally, an FDRA with quasi-elliptic function response is realized without additional (cid:12)ltering circuit. The prototype of the FDRA operating at 3.53 GHz was fabricated and measured to verify the design validity. The measured results show that the impedance bandwidth is 13.6% (3.29{3.77 GHz); the gain is basically stable at 5.7 dBi within the passband; and the two radiation nulls are located at 3.05 GHz and 3.88 GHz, respectively.

|Crosstalk between interconnected lines is considered from two perspectives in this study. From a physical space perspective, the four transmission lines are reduced to two transmission lines. Meanwhile, the replacement of signal transmission of four-channels 2PAM (Pulse Amplitude Modulation) with signal transmission of two-channels 4PAM can reduce the quantity of transmission line and increase the space between the transmission lines. Thus, it can reduce the crosstalk. Under the same signal-to-noise ratio (SNR), the change in symbol error rate (SER) after signals of four-channels 2PAM are changed to those of two-channels 4PAM is given. Results show that the latter has an advantage in anti-crosstalk compared with the former in terms of the in(cid:13)uence of crosstalk on SER. From the signal space perspective, applying signal linear combination transformation can convert the multiplexing signals in the interconnects into orthogonal mode. This process can cancel the crosstalk. In this study, the two methods are combined to save wiring while reducing crosstalk. ADS simulation results show that the eye pattern of 4 PAM signal recovers well by saving half the number of transmission lines.

This paper proposes a new method to produce and reconfigure transmission zero(s) (TZ(s)). The TZs are constructed by using lumped elements in series with dielectric resonators, which is different from conventional methods such as introducing a cross coupling between nonadjacent resonators and mixed coupling between adjacent resonators. The proposed filter consists of two dielectric resonators, a capacitor, an inductor, two PIN diodes, etc. Two PIN diodes are used as switches to realize reconfigurable TZ(s). The mechanism is analyzed theoretically. An equivalent schematic diagram is simulated by using ADS software. The simulated results show that the structure can realize four response states, i.e., no TZ in the stopband, one TZ in the lower stopband, one TZ in the upper stopband, and two TZs in both sides of the stopband of the filter, respectively. The dielectric resonators (DRs) were made of dielectric ceramics with high dielectric constant of about 92. The filter was fabricated on a dielectric substrate and measured by using a vector network analyzer and double regulated DC power supply.
