Fig. 1 IEEE 802.11 WLAN frequency allocations. t Due to the rapidly growing demand for broadband wireless communication, the operating frequency is moving toward the 5 GHz U-NII band. With a maximum data rate of 54 Mb/s, the IEEE 802.11a wireless LAN (WLAN) standard specifies 300 MHz allocation of...

Defected ground structures (DGS) etched in the metallic ground plane of microstrip lines, also known as photonic bandgap (PBG) structures, are attractive to obtain unwanted frequency rejection and circuit size reduction. Research on the PBG was originally carried out in the optical regime 1,2 and has recently started with...

Microwave thermal noise has long been employed for built-in test (BIT) of receivers and radiometers. Today’s compact solid-state noise sources are broadband and extremely stable making them very useful signal sources for a variety of tests. What is not commonly known is how many different types of BIT systems...
