This paper presents a miniaturized triple band multi frequency antenna. The proposed antenna can generate two separate impedance bandwidths to cover all the 2. 4/5. 2/5. 8-GHz WLAN operating bands and the 2. 5//5. 5-GHz WiMAX bands. The proposed microstrip-fed antenna mainly consists of a circular ring, U-shape-like slots on substrate, and a defected ground(More)
We consider a distributed multiple access system (MAC) with bursty arrivals. The transmissions are grouped into slots and the users are frame-synchronized. At the start of each time slot, variable sized packets independently arrive at each of the transmitting terminals. The packets are to be delivered to a common receiver within a certain number of slots(More)
