This is the inaugural Special Issue covering the Loughborough Antennas & Propagation Conference (LAPC), an international conference that has been held every year since 2005 at Loughborough University in the United Kingdom. The Special Issue focuses on the 2015 Loughborough Antennas & Propagation Conference held on 2-3 November 2015 at Burleigh Court Conference Centre within Loughborough University. The conference program for 2015 included 12 distinguished invited speakers who delivered talks on the four main themes of the conference: Reconfigurable Antennas, Biomedical Applications (including wearable), Space and Industrial Applications, and Smart Materials for EM. A total of 174 submissions from 41 different countries were reviewed by a dedicated panel of 74 reviewers, and 153 papers were selected to be included in the conference proceedings. In keeping with the single-track format of the conference, all of the regular papers were presented in open poster sessions. Based on the reviewer scores, a selection of the best papers that were presented at the conference were invited by the Chairs to submit extended versions of their papers to be included in this Special Issue. After extensive peer review, the following 12 papers were accepted for publication, several of which received prizes in the IET Best Student Paper and the Best Non-Student Paper categories at the conference. P. Callaghan, R. Huelin and M.H. Sagor, “An Investigation into use of Double Layer Grid Structures for Building FSS” I. Issa, K.L. Ford, M. Rao and J. Wild, “The Enhancement of Radio Frequency Magnetic Field for a 1.5 Tesla Magnetic Resonance System Using a High Impedance Surface” S.S. Bukhari, W.G. Whittow, J.C. Vardaxoglou and S. Maci, “Dipole-slot-dipole Metasurfaces” K. Yang, X. Bao, P. McEvoy and M.J. Ammann, “A Back-to-Back Beam Switching Microstrip Patch Antenna” S. Zhang, A. Paraskevopoulos, C. Luxey, J. Pinto and W. Whittow, “Broadband Embroidered Spiral Antenna for Off-body Communications” S.S. Zhekov, A. Tatomirescu, E. Foroozanfard and G.F. Pedersen, “Experimental Investigation on the Effect of User's Hand Proximity on a Compact Ultrawideband MIMO Antenna Array” S. Zhang, R.K. Arya, S. Pandey, Y. Vardaxoglou, W. Whittow and R. Mittra, “3D-Printed Flat Lenses for Microwave Applications” W. Wei, K. Mahdjoubi, C. Brousseau and O. Emile, “Horn Antennas for Generating Radio Waves Bearing Orbital Angular Momentum (OAM) by Using Dielectric Lenses” S. Ulaganathan, S. Koziel, A. Bekasiewicz, I. Couckuyt, E. Laermans and T. Dhaene, “Data-Driven Model Based Design And Analysis Of Antenna Structures” F. Sheikh, Fawad, N. Zarifeh and T. Kaiser, “Terahertz Band: Channel Modelling for Short-Range Wireless Communications in the Spectral Windows” C. Gennarelli, F. D'Agostino, F. Ferrara, R. Guerriero and M. Migliozzi, “Optimal Sampling Interpolation over a Plane from Transient Bi-Polar Near-Field Data” F. D'Agostino, F. Ferrara, C. Gennarelli, R. Guerriero and M. Migliozzi, “Two Efficient Procedures to Correct the Positioning Errors in the Plane-Polar Scanning” We believe that the selected papers provide a representative sample of the latest developments in antennas and propagation. They combine technical insights from both industry and academia, something which is characteristic of the overall work presented at the conference. We sincerely hope that you enjoy reading these latest developments. We would like to thank the authors for their excellent contributions and to thank all the reviewers for the time and effort that they dedicated to improve the quality of the papers. We would also like to thank the Editorial Board of IET Microwaves, Antennas and Propagation for their assistance and guidance in the preparation of this Special Issue, especially the Editor-in-Chief Dr. Stavros Iezekiel and the IET Editorial Office. Finally, we gratefully acknowledge the support of The IET for the sponsorship of the IET Best Student Paper prize at LAPC.
