Abstract: A small slot-loaded patch antenna design developed for receiving both L1 and L2 bands GPS signals is discussed. The dual band coverage is achieved by using a patch mode at L2 band and a slot mode at L1 band. High dielectric material and meandered slot line are employed to reduce the antenna size down to 25.4 mm in diameter. A DUAL-BAND CIRCULARLY POLARIZED STUB LOADED MICROSTRIP ... can be fabricated easily in practice. Therefore, slot loaded patch antenna with a coaxial feed was considered as a base structure. 2.1. Basic Antenna Structure Dual frequency operation of the slot loaded patch antenna was investigated in [13]. When two narrow slots are etched close to the radiating edges, the TM100 mode is perturbed a little ...

INTRODUCTION Microstrip antenna inherently has a low bandwidth that limits its application in practice. Several approaches have been made to improve the bandwidth of the single layer patch antenna, such as use of a thick or foam substrate [1-2]. A Review on Slot Loaded Rectangular Patch Antenna for Dual ...
In this paper, a design to obtain dual band performance in square microstrip patch antenna has been proposed. This high directive probe feed antenna has only 30 mm 30 mm patch. It provides dual-band operation by means of three narrow slots close and parallel to the patch radiating edges.

Dual-band slot-loaded patch antenna Abstract: A new patch antenna is analysed which provides dual-frequency operation by means of two narrow slots close to the patch radiating edges. The two modes of operations show similar radiating properties. The ratio between the two frequencies can be well controlled within a range varying from 1.6 to 2 ...
