Title: A reconfiguration dual-frequency slot-loaded microstrip antenna controlled by pin diodes
Author: Shynu, S V; Gijo,Augustin; Aanandan,C K; Mohanan,P; Vasudevan, K
Abstract: A novel reconfigurable, single feed, dual frequency, dualpolarized operation of a hexagonal slot-loaded square mwrostrip antenna is presented in this paper. A pin diode incorporated in the slot is used to switch the two operating frequencies considerably, without significantly affecting the radiation characteristics and gain. The proposed antenna provides a size reduction up to 61% and 26% Jor the two resonating frequencies, compared to standard rectangular patches. This design also gives considerable bandwidth up to 3.3% and 4.27%, for the two frequencies with a low operating frequency ratio
