Often amateurs are faced with limitations placed on the space available and the length of wire or number of wires that may be possible in a operational antenna at the shack. There is a particular class of homeowner that does not want to see a web of wires suspended between trees or supporting structures in neighboring property, or an unsightly tower adorned with multiple beam antennas in the ai...

This paper describes the application of genetic programming to synthesize a small form factor, 2 dimensional wire antenna for a 5.2 GHz 802.11a wireless LAN application. Utilizing basic genetic programming techniques and using a novel approach to discretizing the search space leads to a more simple problem representation and implementation. The paper presents simulation results exceeding expect...

Abstract Antenna problem is a phenomenon of plasma induced gate oxide degradation. It directly affects manufacturability of VLSI circuits, especially in deep-submicron technology using high density plasma. Diode insertion is a very effective way to solve this problem. Ideally diodes are inserted directly under the wires that violate antenna rules. But in today’s high-density VLSI layouts, there...

We are presenting by this paper on helical antennas which find important applications in communication systems, primarily because of their circular polarization and wide bandwidth. The helical antenna, first introduced by Kraus in 1946, The geometry of larger helical shape type antenna, which is a doubly helical structure, is fully described by five independent parameters, with the including tw...

Wire bonds are one of the most common interconnects used in microelectronics; however, their application to millimeter wave monolithic microwave integrated circuits (MMICs) may severely decrease overall system performance due transmission loss, radiation and impedance mismatch. The goal this work was optimize a wire-bonded patch antenna minimize losses maximize gain frequency range from 81 83 G...
