Study on a broadband quasi-Yagi antenna for mobile base station

A Broadband CPW-to-Waveguide Transition Using Quasi-Yagi Antenna

A novel CPW-to-waveguide transition utilizing a uniplanar quasi-Yagi antenna is presented. The X-band back-to-back transition demonstrates 33% bandwidth with return loss better than -10dB. This transition should find a wide variety of applications due to its high MIC/MMIC compatibility and low cost.

A Broadband Planar Quasi-Yagi Antenna with a Modified Bow-Tie Driver for Multi-Band 3G/4G Applications

This paper presents a broadband and compact planar quasi-Yagi antenna for multi-band 3G/4G applications. The proposed quasi-Yagi antenna consists of a modified bow-tie driver to increase the bandwidth, a passive reflector and two passive directors to enhance the directivity at the lower and higher ends of the operating band, respectively. A microstrip-to-slotline transition feed is used to achi...

Performance of a Base Station Feedback-Type Adaptive Array Antenna with Mobile Station Diversity Reception

In this paper, Bit Error Rate (BER) performance of Feedback-type Adaptive Array Antenna (AAA) in Frequency Division Duplex/Direct Sequence Code Division Multiple Access system (FDD/DS-CDMA) with Mobile Station (MS) reception diversity will be investigated. The results include the effects of maximum Doppler frequencies (fd) and antenna element spacing at Base Station (BS) under flat fading and f...

Yagi Microstrip Patch Antenna for GPS and Mobile Communication

This paper presents a Wide Bandwidth Microstrip Yagi antenna with very good performance at two operating frequencies (1.128GHz and 1.986GHz).This microstrip antenna works on two band of frequencies .The first band lies between 1.06 GHz to 1.196 GHz and it resonates at 1.128 GHz frequency then its calculated bandwidth is 12.05% and the second band is lies between 1.621GHz to 2.351GHz and it reso...
