Triple-band microstrip patch antenna element for GSM1800, UMTS and HiperLAN2

Abstract

A new small triple-band microstrip patch antenna element is presented. It has been developed to be used in handsets of future multi-standard (GSM1800, UMTS and HiperLAN2) mobile communication systems. A prototype has been designed, fabricated and tested. Good agreement has been obtained between numerical simulations and experimental results.

Two Novel Compact Triple-Band Microstrip Annular-Ring Slot Antenna for PCS-1900 and Wlan Applications

“…In the second design we have tried to make this antenna more compact and efficient by utilizing circular PBG structures. The very similar co-polarization radiation patterns differs our proposed antennas from previously presented multi-band antenna [12][13][14][15][16][17][18]. Also, the E-plane cross-polarization level of the second design is reduced by about 5.5 dB, 0.3 dB and 4 dB in the three resonant bands compared with the first design.…”

“…As shown in Figures 5 and 6, the patterns for both antennas have very low cross-polarization (the co-and cross-polarized fields correspond to E θ and E φ , respectively) levels and the three frequencies have the very same polarization planes that differ our presented antennas from latest developed multi-band antennas [12][13][14][15][16][17][18].…”

“…Also, it is highly desirable to integrate several RF modules for different frequencies into one piece of equipment. Hence, multi-band antennas that can be used simultaneously in different standards have been in the focus points of many research projects [1,[12][13][14][15][16][17][18][19]. Among these standards, the following frequency bands can be mentioned: Microstrip antennas are very attractive because of their low profile, low weight, conformal to the surface of objects and easy production.…”

Miniaturized Balanced Antenna with Integrated Balun for Practical LTE Applications

“…As a result, several works have recently been dedicated to internal multiband antennas in mobile handset applications. The planar Inverted-F antennas (PIFA) [2], [3], microstrip patch antennas [4], [5] and monopole printed structures [6], [7] have been considered as the most common internal mobile phone antennas. In particular, with the advancement of the LTE technology, smart phones are now broadly used, thus designing new antennas for legacy and future release of the LTE standard, catering for carrier aggregation and multiple wideband frequency bands are now of much interest in the research community.…”
