Investigating the effects of control lines on a frequency reconfigurable patch antenna
The objective of the paper is to investigate the effects
of metallic control lines on a frequency reconfigurable patch
antenna. The designed antenna resonates at 3 different
frequencies in range of 3-4GHz. Simulation and measurement
results of return loss with and without control lines are
presented. We have also discussed the challenges of
implementing the bias lines
A miniature reconfigurable printed monopole antenna for WLAN/WiMAX and LTE communication bands
A reconfigurable printed monopole antenna covering WLAN, LTE, WiMAX and HiperLAN communication bands is presented in this paper. The antenna operates between these frequencies with activation of 2 switches. The proposed antenna is a low profile, miniaturised design and occupies a volume of 20 × 25 × 0.5(25mm 3 ) which makes it an ideal candidate to slot into compact and portable devices. Initial results including antenna design, S-Parameters, Radiation Characteristics and Peak gain at different frequencies is presented and discussed

Analysis of techniques to minimise the interference effects of metallic control lines on reconfigurable microstrip antennas
An analysis of techniques used to minimise the adverse effects of metallic control lines on reconfigurable antenna performance is presented in this paper. The paper addresses the impact of control lines and possible ways to incorporate them into radiating structures with minimal effects on the radiation characteristics of reconfigurable antennas. This is aided by a study performed on a simple reconfigurable printed dipole antenna operating between 1 and 3 GHz. Parametric studies were performed on the length and location of control lines printed on the substrate. Simulation results for different control line configurations are presented and discussed
