In this paper, a new design of high gain and wide bandwidth microstrip patch antenna array containing double meander dipole structure is proposed. Two in-phase resonant frequencies in the Ku-band (12–18 GHz) could be achieved in the double meander dipole array structure, which lead to enhance impedance bandwidth without costing extra design section. Besides, further enhanced gain of 2 dBi of the array over the entire operating frequency range has been achieved by introducing a double-layer substrate technique. The proposed antenna has been fabricated using the E33 model LPKF prototyping PCB machine. The measurement results have been performed, and they are in very good agreement with the simulation results. The measured –10 dB impedance bandwidth indicates that the array provides a very wide bandwidth which is around 30% at the center frequency of 15.5 GHz. A stable gain with a peak value of 10 dBi is achieved over the operating frequency range. The E- and H-plane radiation patterns are simulated, and a very low sidelobe level is predicted. The proposed antenna is simple and has relatively low-profile, and it could be a good candidate for millimeter wave communications.

Based on the traditional dielectric microstrip balun, a new-type coupling balun is presented in this study. The front side of this balun is composed of an open stub and two rectangular patches. One end of the rectangular patches is opencircuited, and the other end connects with the dipole. On the back side, there are two other rectangular patches with one end grounded and the other end open-circuited. When using such balun for feeding, one can still get a wide bandwidth, and more importantly, obtain higher port isolation. Compared with the dipole fed by the traditional balun, the maximum/average port isolation of the dipole fed by the new-type one is increased by 10.8 dB/7.9 dB.The new-type balun has a good application prospect in dual-polarized antenna.

“…To solve the above issue, some sequential rotating array antennas based on a sequential-phase (SP) feeding network were proposed in. [8][9][10][11][12][13] Typically, a coaxially fed unidirectional CP array antenna, which consists two substrates and an air band gap, carried out a 70% impedance bandwidth and a 55% AR bandwidth 9 ; a stacked array antenna, which is composed by some double-layer patches, obtained a 43.2% impedance bandwidth and a 23.5% AR bandwidth. 14 However, these antenna arrays are highly profiled because of their noncoplanar feeds or multilayer structures.…”

Grooving or subtracting a projection of the antenna on the ground is one of the effective methods to both improve the axial-ratio (AR) bandwidth and impedance bandwidth of a circularly polarized (CP) antenna. A bidirectional radiation, meanwhile, can be produced. Unfortunately, these methods will result in a decrease in the gain of the antenna due to a reduction of its ground size. To solve this issue, a conductive plane or a cavity is usually introduced at the antenna's bottom, but it will lead to a high profile and destroy the bidirectional radiation of the design. In this article, a CP array antenna based on a sequential-phase (SP) feeding network is taken as an example. Only the projection of the feeding network is preserved, while other conductors on the ground are subtracted. The simulated peak gain of this design is only 5.04 dBic. In order to obtain an ultra-wideband, a wide AR bandwidth, a moderate gain and a low profile of the antenna, a method of etching a circle of ground around the edge of the substrate is presented to expand the ground into a large irregular area. The measured results show that the proposed design can exhibit a 90.9% 10-dB impedance bandwidth, a 42.4% (5.2-8 GHz) 3-dB AR bandwidth, a 7.17 dBic peak gain, and a very low profile of 0.006λ L . This method is very simple to implement and does not need to modify the original antenna structure.It may be applied to conveniently improve the performance of the bidirectional radiation CP antenna.
