This paper proposes a reconfigurable microstrip patch antenna design for wireless ISM band applications. The antenna simultaneously uses PIN Diodes to switch between linear and circular polarization at 2.45 GHz and uses Varactor Diode to continuously tune the operating frequency from 1.73 GHz to 2.45 GHz. The antenna performance is characterized as a combination of ON/OFF state of PIN Diode and a bias voltage of Varactor Diode varying from 0.8V to 10V. A good agreement between simulation and measurement is obtained which validates the proposed method. The proposed frequency/polarization reconfigurable antenna is promising for various applications in wireless ISM band such as DCS (1710 – 1880 MHz), PCS (1850 – 1990 MHz), GSM 1800, GSM 1900, UMTS (1920 – 2170 MHz) and WiFi/Bluetooth (2.4 – 2.5 GHz).

A high-directivity patch antenna with broadside directivity is appealing, since a constrict beam can be obtained without the need of using an array of antennas. Hence, the solution becomes barer as there is no need for a complicated feeding network. In this senate, this paper presents a novel patch antenna design with high directivity in the broadside direction by using HFSS. The proposed finite element method is employed to design the rectangular microstrip patch antenna. The patch is divided into symmetrical rectangular pieces and has a small overlap area among them. This averts optimized geometries where rectangular pieces have only an infinitesimal connection. Hence, the proposed method is robust for manufacturing. The antenna functions in a higher order mode at 8.40 GHz, 16.5 GHz and the geometry fits inside a patch of 41mm £ 26mm on a substrate with a relative permittivity of 2.1 and a thickness of 1.75mm resulting in a gain of 9.94 dBi. The strength of this design is the use of FEM to select the optimized shape and the feeding place instead of a known shape and a fixed feeding place. The antenna has been fabricated and the simulation results are in good agreement with the measurements. These results in a less complicated design of a single high-directivity patch and enhance the gain and improve bandwidth.

A design approach for a microstrip patch antenna to achieve the reconfigurable dual-band operation with a tunable device is presented in this work. The approach uses a BB833 varactor diode in the middle of a slotted patch antenna which which is able to produce dual-band resonant frequencies. The reconfigurable antenna is designed and simulated in CST Microwave Studio® software and is later, fabricated on a FR-4 substrate with a dielectric constant,  of 4.5, loss tangent, tan δ of 0.019 and thickness, h of 1.6 mm. By changing the DC voltages of the varactor diode, different capacitance values of the varactor diode are obtained which dictate the specific resonant frequencies. From the simulation results, the capacitance value of 0.5 pF with a bias voltage of 2.0 V is chosen as it produces the required dual-band resonant frequencies at 3.38 GHz and 5.37 GHz for desired applications in the m-WiMAX and WLAN bands.

Multiband reconfigurable patch antenna plays a vital role in wireless communication applications. By changing the current path on the patch a multiband reconfigurable antenna can be achieved. A simple multiband frequency reconfigurable microstrip patch antenna is presented in this paper. The proposed antenna structure is simulated in CST microwave studio. This antenna operates between 1.3 to 5.6 GHz with more than fifteen different frequencies. The antenna is analyzed for four different configurations. The designed antenna is resonating at five different frequencies (1.45 GHz, 2.36 GHz, 3.09 GHz, 3.6 GHz and 5.45 GHz) when both PIN diodes are ON. When PIN diode D1 is ON and D2 is OFF the antenna is resonating at 1.4 GHz, 2.22 GHz, 2.5 GHz, 3.08 GHz and 3.59 GHz. When D1 is OFF and D2 is ON the antenna is resonating at 2.34 GHz, 3.2 GHz, 3.62 GHz and 5.38 GHz frequencies. The slotted antenna or when both PIN diodes are in OFF condition antenna is resonating at 2.22 GHz, 2.49 GHz, 3.21 GHz, 3.6 GHz and 5.42 GHz. For each configuration the antenna parameters like gain, VSWR, directivity and radiation patterns are analyzed.
