Recently PGB (photonic band gap) filters show a great
development. Here we will present two different PGB filters with
lattice etched in the ground plane. The rejection band characteristic
is function of the number and shape of elements etched. Th
ese
filters are modelling by the FWCIP method.
This research present a novel reconfigurable patch antenna
to support 5G and previous generations frequency bands ,at this
proposed method multi slots have been made in microstrip patch
antenna and three PIN diode at ground The Reconfigurability i
s
done by changing the status (ON - OFF) of the PIN diode on ground
substrate to get butter current distribution on the surface which
led to multiple BW .
.In this paper we present a new method to improve microstrip
patch antenna bandwidth to support 5Generatiton and previous
generations frequency bands ,at our proposed method multi slots
have been made in microstrip patch antenna to get the
maximu
m current distribution on the surface & get desired
improvements.
In this research, tri-band microstrip band pass filter (BPF) has
been designed at frequencies (2.37,3.32 ,5.2)GHz which are
located at the domain of WiMAX and WLAN systems’
application by using tri-section stepped impedance resonators
TSSIRs with
open stub and zero feed line. By changing ratios
of impedance of stepped impedance resonator.

Novel rejected and passed band devices are obtained using
techniques in two dimensional Photonic Band Gap microstrip
structures. The microstrip is engraved in a PBG dielectric
constituted of a via holes array and enclosed in a metallic box. The
b
oundary element method (BEM) and the fast wave concept
iterative process (FWCIP) are combined to evaluate the
characteristic of this structure.
