“…This topology is expected to be very suitable in view of the specific features needed for the patch current amplitude and phase distributions: when the E-vector of the excitation field is parallel to the slotted side of the patch, the radiation field has predominantly a linear polarization. It is worth mentioning that, to the knowledge of the authors, no slotted strip-frame patches of this kind have ever been used in printed planar or cylindrical antennas [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. It is clearly shown in this paper that slotted strip-frame patches are effective for cylindrical microstrip antenna arrays (CMAAs) fed by a cylindrical microstrip line.…”

Abstract-A cylindrical microstrip array antenna with 5 pairs of coupled slotted strip framed patches is analyzed. The patches are proximity-fed by a cylindrical microstrip line. In order to extract the reflection coefficient from the standing wave pattern on the microstrip line, its length is about 5 wavelengths. To the best of the authors' knowledge proximity-fed cylindrical arrays have not been analyzed before using a rigorous MOM model that takes into account all electromagnetic couplings between patches and feeding line. The paper consists of three parts. The first part describes a plane wave excitation of the cylindrical microstrip structure. It introduces some innovating theoretical developments, like the improvement of the asymptote for the spectral Green's function and the explicit surface wave contribution. The second part calculates the radar cross section of the cylindrical microstrip structure with single and coupled slotted strip framed patches. The resonant frequencies, and the amplitude and phase of the current distribution are analysed. The third part describes a design for a proximity-fed array of 5 coupled slotted strip framed patches. It gives the reflection coefficient, current distribution on the patches, and radiation pattern. A very low level of cross polarization (< −40 dB) is achieved. It is shown that the resonant frequencies of the cylindrical array and its planar analogue lie very close to each other. This is due to the common nature of the low frequency slot resonance for the slotted strip framed patch.

“…For example, many researches are placed on UE antenna designs and realizations which lead to multiband antennas [2][3][4][5][6][7][8][9][10][11], miniaturized antennas with low return loss [12][13][14][15][16] are successful developed, yet these antennas are all designed without considering the isolation between them. Papers [17][18][19][20] analyze the dual-mode interference between UWB and cellular systems, and the multi-mode co-existence between cellular systems is also included in [21][22][23][24][25], but problems exist that the interference scenarios they researched are all single-mode single-link for each UE.…”

Abstract-This paper investigates the performance of DCS1800/CD-MA-EVDO dual-mode dual-link (DM-DL) UE and presents an effective solution which is based on our designed high isolation antenna for the UE local electromagnetic interference (EMI). To this end, a DCS1800/CDMA-EVDO DM-DL UE model is firstly brought out, together with its system model, interference analysis and performance evaluation. Simulated results show that the DCS1800 (CDMA-EVDO) local interference will cause a sharp deterioration of the CDMA-EVDO (DCS1800) receiving sensitivity. To solve this problem, then, a compact and high isolation double-band handset antenna is given with its structure designed and performance validated by measurement. On the basis of this antenna and existing UE bandpass filter, we introduce a solution called "passive isolation" to eliminate the local interference. Finally, the performance of DCS1800/CDMA-EVDO DM-DL UE is researched again by our solution, simulated results indicate that the isolation effect is quite good and the DM-DL UE can work normally.

Abstract-The fine-grained parallel micro-genetic algorithm (FGP-MGA) is developed to solve antenna design problems. The synthesis of uniformly exited unequally spaced array is presented. Comparison with the micro-genetic algorithm (MGA) has been carried out. It is seen that the FGPMGA significantly outperforms MGA, in terms of both the convergence rate and exploration ability. The FGPMGA can also reduce the optimization time. Then the FGPMGA and the body of revolution finite-difference time-domain (BOR-FDTD) are combined to achieve an automated design process for conical corrugated-horn antenna. Numerical simulation results show that the horn antenna has good impedance matching (the VSWR is less than 1.5), stable beamwidth and gain, as well as good rotation symmetry patterns over the whole band 8∼13 GHz.
