Electronically Reconfigurable WLAN Band-Notched MIMO Antenna for Ultra-wideband Applications
─ A low-profile electronically reconfigurable WLAN band-notched dual port multiple-input multipleoutput (MIMO) antenna design for ultra-wideband applications has been presented. Antenna elements exhibit good impedance match (S11 ≤ -10 dB) over entire ultrawideband (3.1 to 10.6 GHz) spectrum. The decoupling structure is used to improve isolation (S12/S21) above 20 dB over entire UWB band. Moreover, reconfigurable band-notching is achieved by inserting PIN diodes along the inverted L-shaped slots, in each radiator. Notch at WLAN (5.5 GHz) frequency band is achieved by switching the PIN diode to ‘OFF’ state. The antenna design is fabricated as well as measured, and the results suggests that the proposed design with switchable WLAN band-notch characteristics is suitable candidate for ultra-wideband applications. Index Terms ─ Isolation, multiple-input multiple-output (MIMO), PIN diodes, reconfigurable, ultra-wideband (UWB), WLAN band-notch.
期刊介绍：
The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study.
The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed.
A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected.
The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
