Abstract-We investigate the efficiency of a metasurface supporting spoof plasmons to control the electromagnetic emission of a radiating element. The three-dimensional metasurface is made of an array of metallic grounded rods, and it is used as the substrate of a printed antenna. Such a substrate provides a transmission band at low frequencies, corresponding to spoof plasmon propagation, and a total electromagnetic band gap above the cut-off frequency. We show how an efficient and directive emission with low side-lobe levels and backward radiation can be obtained when the operating frequency of the antenna is considered in the band gap. The role of the spoof plasmons is further demonstrated by tuning the transmission band at the operating frequency. The proposed meta-substrate is an original and efficient alternative to reshape the emission of electromagnetic sources.

Problem statemet: Wideband compact antenna is highly demandable due to the dynamic development in the wireless technology. Approach: A simple, compact EBG microstrip antenna is proposed in this study that covers a wideband of 250 GHz and the design is conformal with the 2.45 GHz ISM band (WLAN, IEEE 802.11b and g)/Bluetooth/RFID applications. Results: A 6×6 array of square unit cell formed the EBG structure which is incorporated with the radiating patch to enhance the antenna performances. This design achieved an impedance bandwidth of 10.14% (2.34-2.59 GHz) at -10 dB return loss and VSWR ≤ 2. Simulated radiation pattern is almost omnideirectional. Conclusion/Recommendations: The simulated results prove the compatibility of the EBG antenna with the 2.45 GHz ISM band applications. Further enhancement of the antenna performance with improved design is under consideration.

Abstract-For the application of K connector (K103F) at Ka-band, many problems exist, due to the complex method of installation. In this paper, the test fixture is simplified, and the performance of this section is improved with the Electromagnetic bandgap (EBG) structure. Simulation results are presented for the connection structure with EBG; plots of the input reflection of geometrical and physical parameters are reported and commented on.
