Abstract
A co-linearly polarized wideband microstrip antenna with a single shared patch feeding by two parallel L-probes is proposed in this letter. The shared patch introduces a new coupling path for the L-probes. The coupling coefficients of the two L-probes, as well as the L-probe and the patch, are quantitatively derived based on the coupled resonators theory. It is proved that by adjusting the geometries and dimensions of the two L-probes and the patch, a natural wideband high isolation can be obtained. A demonstration example is designed and measured to validate the feasibility of the proposed scheme. The results show that the proposed antenna can achieve impedance matching of −10 dB and high isolation of 20 dB in the frequency range from 3.2 GHz to 4 GHz. Besides, the measured efficiency ranges from 91% to 99% with an average realized gain of 7.4 dB. Furthermore, another example with a lower height is also designed to justify the practical usefulness, showing 19.8% decoupling bandwidth.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
