چکیده
Fig. 1 Geometry of the proposed antenna (a) topview and sideview. (b) overall figure (c) picture of antenna A planar inverted-F antenna type tunable antenna with Ushaped slot is proposed. Two Varactor diodes are integrated between the slot and bias feeding strip line for tuning the operating frequency. This antenna covers from 1.64GHz to 2.05 GHz refer to the dc bias voltage from 0V to 20V. The frequency tuning range is about 410 MHz bandwidth which covers several mobile communication bands of DCS(1710~1880MHz), PCS(1750~1870MHz) and PCS(USA)(1850~1990MHz). This antenna occupies a compact volume of 40 x 15 x 8 . The simulation result is based on the Finite Integral Method. 3 mm

Modified U-Slot Stacked Micro-Strip Patch Antenna for Ultra-Wideband Applications in S Band, C Band and X Band
The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...
متن کاملA Dual-Band U-Slot PIFA Antenna with Ground Slit for RFID Applications
In this paper, a Planar Inverted-F Antenna (PIFA) with U-Slot (U-PIFA) and slit in ground is introduced. The proposed PIFA is compact with single coaxial feed, single short strip, and single short pin. The main achievement of this research was the design of ISM Microwave bands 2.45/5.8 GHz dual band PIFA antenna by using slit in ground to control the selection of lower resonance frequency witho...
متن کاملA Frequency Tunable PIFA Design for Handset Applications
A frequency tunable planar inverted F antenna (PIFA) is presented for use in the following bands: DCS, PCS, and UMTS. Initially, the tuning was achieved by placing a lumped capacitor, with values in the range of 1.5 to 4 pF, along the slot of the radiator. The final tuning circuit uses a varactor diode, and discrete lumped elements are fully integrated with the antenna. The antenna prototype is...
متن کاملWideband Tunable PIFA Antenna with Loaded Slot Structure for Mobile Handset and LTE Applications
A compact planar inverted F antenna (PIFA) with a tunable frequency response is presented. Tuning of the resonant frequency is realized by loading a varactor on an embedded slot of the proposed antenna structure without further optimizing other antenna geometry parameters. The antenna exhibits a wide frequency range from 1570 to 2600 MHz with a good impedance matching (S11 ≤ -10dB) covering the...
متن کاملChannel capacity of dual-element modified PIFA array on small mobile terminal
A study on the MIMO channel capacity of a modified dual-element planar inverted-F antenna (PIFA) array is presented. The dual-element PIFA array consists of two modified PIFAs which are mounted on a small mobile terminal operating at 2.5 GHz. The relationship between mutual coupling and channel capacity is analysed by comparing the modified dual-element PIFA array with a conventional dual-eleme...
