“…For l 1 = 1.38 cm and w = 0.05 cm, rectangular slot cut dual band RMSA operates at dual frequencies of 3640 and 4080 MHz, with VSWR BW of 2.8 and 2.45%, respectively, as shown in Fig. 1(a, b) [12]. The dual band response is reported due to the excitation of additional mode near the TM 11 mode frequency of the equivalent RMSA.…”

“…The loop is formed due to the close proximity of TM 11 and TM 02 modes. In [12] it is reported that circular polarization is realized at the frequencies where loop is present. However simulated axial ratio in broadside as well as end-fire direction was found to be more than 20 dB.…”

“…In most of the reported and studied slot (rectangular slot or U-slot) cut configurations, broadband or dual band response was realized with respect to fundamental patch mode. Recently by cutting rectangular slot or plus shaped slot on one of the edges of rectangular MSA (RMSA), a dual band or broadband RMSA has been realized [12]. The said configurations were reported to be functioning around TM 11 mode frequency of equivalent RMSA and slots are reported to introduce a mode near TM 11 mode frequency.…”

The more frequently used technique to realize broadband and dual band microstrip antenna is by cutting the slot at an appropriate position inside the patch. In this paper, an in-depth analysis of dual band rectangular slot cut rectangular microstrip antenna and plus shaped slot cut broadband rectangular microstrip antenna is presented. The dual band slot cut antenna is reported to be resonant at 3640 and 4080 MHz. Through the analysis it was observed that the slot modifies the resonance frequencies of TM 11 and TM 02 mode of the rectangular patch and optimizes the impedance at them to realize dual frequency response. Further when an additional horizontal slot is cut inside the above rectangular slot which realizes plus shaped slot, it further reduces TM 02 mode resonance frequency and along with the TM 11 patch mode, yields broadband response. The proposed analysis gives an insight into the functioning of the slot cut patch antennas operating at higher order modes as well as it will help them in designing them in given frequency band.

Rectangular Microstrip Patch Antenna with Double L-Shaped Slots for Enhanced Bandwidth

Rectangular microstrip patch antennas, although having many advantages, usually suffer from having narrow bandwidth. Changing the feed point, or adding slots to the patch or to the ground plane or the addition of resonant circuits to the structure are different methods that can be applied for enhancing the bandwidth. Slots are usually added for creating multiple band operations. In this work, design and implementation of a rectangular microstrip patch antenna with double L-Shaped slots is proposed for enhanced bandwidth. Design is done with simulation verification of the problem and testing of two prototype circuits. Simulated and measured responses for both of the antenna circuits are demonstrated. One circuit indicated about 600MHz bandwidth at 2.6GHz center frequency and the other one about 1GHz bandwith with center frequency being around 2.4GHz. 
