Hybrid Design of a Fractal-Shaped GSM/UMTS Antenna

Multiband Fractal Planar Inverted F An- Tenna (f-pifa) for Mobile Phone Application

The design of a novel Fractal planar inverted F antenna (F-PIFA) based on the self affinity property is presented in this paper. The procedure for designing a Fractal Planar Inverted F Antenna is explained and three different iterations are designed for use in cellular phones. The F-PIFA has a total dimension of 27mm× 27mm and has been optimized to be operational at GSM (Global System for Mobil...

Innovative Design of a Planar Fractal-Shaped GPS / GSM / Wi-Fi Antenna

طراحی و ساخت آنتن مایکرواستریپ سه بانده و دوپلاریزه برای BTS

In this paper, a simple dual-band dual-polarized aperture stacked patch antenna with double sided notch is presented. This antenna is suitable for operation in telecommunication base stations. One of the bands covers the GSM band, while the other covers both DCS and UMTS bands. The proposed antenna shows good port decoupling of less than -30dB for dual linear polarization over its operating ban...

A compact stacked Quasi-fractal microstrip antenna for RFID applications

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
