“…Inorder to decrease the coupling, the ground guard fence was used between the microstrip lines and the disadvantage in using the ground guard fence is that, it increases the size of the printed circuit board. It is common to introduce slots in the reference plane to provide the DC isolation [6]. An asymmetrical grounded resonators technique was proposed to reduce the EMI for slot crossing differential signals.…”

Now-a-days, the usage for the high speed printed circuit boards are increased. Inorder to satisfy the high demand of low cost and size reduction, chips must be integrated in a same package in which the signal integrity issues may occur. One of the major issues is radiated emission. The common mode and differential mode radiation occur when the differential signal crosses the splitted reference plane. In this paper, to reduce the common mode radiation, asymmetric resonators with the interdigital capacitors on the splitted ground plane with shorting vias is implemented. The physical dimensions for the stub and the interdigital capacitors are determined by using the design theory of transmission line model. The insertion loss, return loss and the field pattern are determined using the Ansoft HFSS Tool.

A microstrip-line-fed Isosceles Trapezoidal Dielectric Resonator Antenna (ITDRA) with a parasitic strip and modified ground plane is introduced. It is proved by simulation and experiment that the antenna's resonant frequency can be lowered and the bandwidth can be increased considerably by introducing a slot and optimizing its position and dimensions in the ground plane. The proposed antenna is a wide band antenna with a 2 : 1 VSWR bandwidth of 21.5% centered at 2.51 GHz and exhibits good radiation characteristics and moderate gain in the entire operating band. The antenna covers important application bands viz. ISM: Bluetooth/WLAN 2.4/Wibree (802.11 b/g/n)/ZigBee, WiBro and DMB. The wideband response in the relatively lower frequency range which includes the above mentioned application bands are not much seen anywhere in literature. Details of the design along with experimental and simulation results are presented and discussed.
