A reconfigurable dual-frequency rectangular slot antenna using MEMS technology is presented. In this structure, a rectangular slot antenna is integrated with MEMS cantilever type capacitors. Simulation results show that the structure has a dual frequency behavior where both of the resonant frequencies can be reconfigured dynamically. By the actuation of MEMS cantilevers, the lower resonant frequency shifts 1.2 GHz, whereas the higher resonant frequency has a shift of 330 MHz without any distortion of the radiation pattern. The structure is currently in fabrication.

This paper presents a reconfigurable dual-frequency rectangular slot antenna using MEMS technology. MEMS fixed-fixed beam type capacitors loading the antenna are actuated electrostatically to change the equivalent capacitance of the antenna which provides shift in the resonant frequencies. The measurement results show very good agreement with the simulation results and the resonant frequencies are shifted 1 GHz and 350 MHz continuously at around 8.5 GHz and 10.5 GHz, respectively.
Design of a Re-configurable dual frequency microstrip antenna with integrated RF MEMS switches
Onat, Sinon; Ünlü, Mehmet; Alatan, Lale; Demir, Şimşek; Akın, Tayfun (2005-07-08)
The complete design of a re-configurable dual frequency antenna structure, including its integrated RF MEMS switches and their actuation lines together with a CPW feed, is introduced. The number of switches used in the inset is decreased compared to the hybrid design we presented previously (Onat, S. et al., IEEE Int. Antennas and Propag. Symp., vol.2, p.1812-15, 2004). Instead of utilizing available RF MEMS switches, new switches suitable for this application are designed. Two different switch configuratio...
Wideband omnidirectional and sector coverage antenna arrays for base stations
Alatan, Lale (2018-01-01)
By using parallel strip line fed printed dipole antennas as array elements, an omnidirectional antenna array and a wide angle sector coverage array operating in octave band are designed. A maximum deviation of ±1.25 dB from the omnidirectional pattern is achieved for the omnidirectional array, and the average gain of the antenna was measured as being 5 dB in the 1.35–2.7GHz band. For the sector coverage array, a special reflector design is utilized to maintain a half power beam width of around 115◦ with a s...
Reconfigurable antenna structure for RFID system applications using varactor-loading technique
Sevinç, Yusuf; Kaya, Adnan (2012-01-01)
A novel method is presented for electrically tuning the frequency of a compact radio-frequency identification (RFID) tag antenna. A tuning circuit, comprising a radio frequency (RF) switch and discrete passive components, was completely integrated into the antenna element, which is thus free of DC wires. The low-profile printed antennas were fabricated together with the layouts of the DC control circuits and other RF/baseband circuit footprints. A surface-mounted varactor was applied as a frequency-tuning e...

Ergül, Özgür Salih (2006-11-10)
Circular arrays of log-periodic (LP) antennas are designed for broadband applications. A sophisticated electromagnetic simulation environment involving integral equations and fast solvers is developed to analyze the LP arrays both accurately and efficienuy. The resulting matrix equation obtained by the discretization of the electric field integral equation is solved iteratively via the multilevel fast multipole algorithm (MLFMA). Genetic algorithms interacting with MLFMA is employed to optimize the excitati...
