A Compact Electronically Reconfigurable Dual Frequency Microstrip Antenna for L-Band Applications

Frequency Reconfigurable Antenna for Multistandard Applications

A reconfigurable yagi uda shaped microstrip antenna with switchable frequency is proposed. The proposed antenna has a simple structure, consisting of a square radiating patch and parasitic conductors of rectangular shape. This antenna is designed for multiband like WIMAX, GSM, GPS, FDMA and PCS. PIN diodes are used to switch frequencies between different bands depending on the state of the PIN ...

Pattern Reconfigurable Circular Patch Antenna for Mimo Communications

This paper presents a reconfigurable two-port circular patch antenna that improves the performance of a MIMO wireless communications system through pattern diversity. Different modes of the circular patch antenna can be excited by varying its radius with PIN diode switches. Based on this antenna architecture a practical algorithm that exploits the wireless channel spatial selectivity to select ...

Reconfigurable microstrip patch antenna for WLAN Software Defined Radio applications

A reconfigurable microstrip patch antenna with RF pin diode switches is implemented for dual band of 2.4 GHz and 5.6 GHz WLAN Software Defined Radio (SDR) applications. For the dual band SDR system, the use of a single antenna with a wide bandwidth to cover both of the bands can be limiting for low power level signal applications due to wideband noise as well as changing radiation pattern at di...
